Seven less than the product of 8 and a number equals 4
Answer:
11/8 or 1 3/8 or 1.375
Step-by-step explanation:
From the information given by the question, we can form an equation:
Let us call the number 'n'
8 × n - 7 = 4
We then move the 7 to the other side, changing it from minus to plus:
8 × n = 4 + 7
So,
8 × n = 11
We divide both sides by 8, to leave n on one side of the equation.
n = 11/8
Therefore, n = 11/8 or 1 3/8 or 1.375
Find the distance between the two points. Round to the nearest tenth. (-1, 4) and (1, -1)
Step-by-step explanation:
The distance between two point (x_1, y_1) and (x_2, y_2) is
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Therefore, the distance between (-1,4) and (1,-1) is
[tex]d=\sqrt{(1-(-1))^2+(-1-4)^2}=\sqrt{4+25}=\sqrt{29}=5.4[/tex]
there are 16 marbles in a bag 12 of them are blue and 4 are yellow. what is the probability of picking a blue marble then a yellow marble without replacing the first one
11/20
3/7
1/5
Answer:
1/5
Step-by-step explanation:
the prob that you will pick a blue marble would be 12/16, easy.
then the prob of picking a yellow marble after that would be 4/15 since one marble is already missing. multiply the numerator and denominator of each fraction. so 12 x 4 and 16 x 15 to get 48/240. then divide each by 48 to get 1/5.
the answer is 1/5

Find the Midpoint of (2,8) and (-2,0)
if you could show your work that'd be great
Answer:
Midpoint= (0, 4)
Step-by-step explanation:
[tex]\boxed{midpoint = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2}) }[/tex]
Using the formula above,
midpoint
[tex] = ( \frac{2 - 2}{2} , \frac{8 + 0}{2}) [/tex]
[tex] = (0, \frac{8}{2} )[/tex]
[tex] = (0,4)[/tex]

Add a positive number to a number by counting up from that number, and add a negative number to a.number by counting down from that number.An integer plus its opposite sum to zero.The opposite of a number is called the additive inverse because the two numbers' sum is zero.After making several scale drawings Joseph decides on the best placement for a new grillon deck He uses a scale of 2 cm for every 5 in What is the actual area of the space for Joseph's new square inches ?
Answer:
2250
Step-by-step explanation:
The actual areas is 1125 in²
A scale drawing can be described as a drawing of an original image that is reduced by a constant proportion to the original image.
scale of the drawing = original dimensions / dimensions of the scale drawing
The scale used by Joseph = 2 cm : 5 inches
This can be simplified further by dividing by 2
1 cm : 2.5 inches
Based on the image, the dimensions of the grill are 10 cm x 18cm
The length of the actual grill = 18 x 2.5 = 45 inches
The width of the actual grill = 10 x 2.5 = 25 inches
Area of a rectangle = length x width
Area of the actual space for the grill = 25 x 45 = 1125 in²

Hi ;-)
[tex]-28=2x+8-5x\\\\2x+8-5x=-28\\\\2x-5x=-28-8\\\\-3x=-36 \ \ /:(-3)\\\\\huge\boxed{x=12}[/tex]
Answer:
x=12
Step-by-step explanation:
-28=2x+8-5x
-28=-3x+8
Add 3x on both sides:
3x-28=-3x+8+3x
3x-28=8
Add 28 on both sides:
3x-28+28=8+28
3x=36
Divide 3 on both sides:
3x/3=36/3
x=12

Hi! I'm happy to help! (sorry for the wait, my computer crashed)
A linear function is where one variable is independent (x), and another is dependent. This means that we use x to solve for y, y depends on x to be found.
To solve this, we use an equation call slope intercept form, which states that y=mx+b.
There is only 1 solution line. (to solve for how to find y, you only have to have two verifications)
For our first table, we have x as 1, 2, 3,and 4. y is 3, 6, 12, and 24.
For our first set, with x is one and y is 3, there are infinite solutions, so we have to test and see if it matches the second set of x is 2 and y is 6.
How I like to check for what m will be, I check the first two y values. The first two are 3 and 6. They have an increase of 3, so m will be 3. (this only works when x increases by 1)
With m being 3, we can solve for b, to complete the equation:
3=(3(1))+b
3=3+b
With this, b must equal 0
3=3+0
Now, we just have to check if this equation matches all of the other x values:
6=(3(2))+0
6=6+0
__________________________________
12=(3(3))+0
12=9+0
12≠9
This equation doesn't seem to work, so this is not a linear function.
For our next table, our first two y values are 2 and 5, which have a increase of 3, so our m will be 3 again.
Now, let's solve for b:
2=(3(1))+b
2=3+b
In this case, b will be -1 because 2=3-1
Now, let's check if this matches up with our other values:
5=((3)2)-1
5=6-1
_______________________________
9=((3(3)-1
9=9-1
9≠8
This equation doesn't work, so it is not a linear function.
For our next table, we have our first two y values as -3, and -5. This has a decrease of 2, so our m will be -2.
Now, let's solve for b:
-3=((-2)1)+b
-3=-2+b
In this equation, b will be -1 because -3=-2-1.
Now, let's check our other values:
-5=(-2(2))-1
-5=-4-1
___________________________________________
-7=(-2(3))-1
-7=-6-1
______________________________________________
-9=(-2(4)-1
-9=-8-1
All of these values match, so this is a linear function.
If you wanted to (you don't have to, but if you needed verification) you could check the fourth problem.
Has a decrease of 2, so m would be -2. Plug it in:
-2=(-2(1))+b
-2=-2+b
b would be 0.
Check it on the second problem:
-4=(-2(2))+0
-4=-4+0
Check the third:
-2=(-2(3))+0
-2=-6+0
-2≠-6
The fourth table doesn't match either, so it is not a linear function.
You should choose option 3 because it is a linear function.
I hope this was helpful, keep learning! :D

What is the measure of B?
Select the best answer from the choices provided.
A.33°
B. 57
C. 770
D.123
Answer:
B =57
Step-by-step explanation:
The sum of the angles of a triangle is 180
A+B+C = 180
58+B+65 = 180
123+B = 180
B = 180-123
B =57
The angle sum property of a triangle:
The total measure of the three angles of a triangle is 180°∠A + ∠B + ∠C = 180°
∠A = 58° ∠B = 65° ∠C = x⇛58° + 65° + x = 180°
⇛123° + x = 180°
⇛x = 180° - 123°
⇛x = 57°
Option B is the correct answer

Answer:
4/25
Step-by-step explanation:
Answer:
16% as a fraction is 4/25
Step-by-step explanation:
Every percentage is over a 100. This means that 16% is the same as 16/100 and simplifying this it will be 4/25 ( dividing both by 4)
3 Sean has 8-inch pieces of toy train track and Ruth has 18-inch pieces of train track. How
many of each piece would each child need to build tracks that are equal in length?
Answer Statements:
Answer:
72
Step-by-step explanation:
The smallest number that is divisible by two given numbers is called the Least Common Multiple (LCM) of those numbers.
What's the smallest number that is a multiple of 8 and also a multiple of 18?
One way to find out is to start making lists of multiples:
Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, and so on,
Multiples of 18: 18, 36, 54, 72, 90, 108, and so on.
This method can be a bit tedious, but in this case, it's clear that 72 is the LCM of 8 and 18.
Another method is to use the prime factorization of the two numbers.
Write 8 and 18 as the product of prime numbers; each number has a unique prime factorization.
8 = 2 x 2 x 2 = 2^3
18 = 2 x 3 x 3 = 2^1 x 3^2
To form the LCM, build a product of primes using the highest exponent in either of the two numbers.
LCM = 2^3 x 3^2 = 8 x 9 = 72.

Answer: 36/a^2b
Step-by-step explanation:
Starting with the question 4a^3b^-2*9a^-5b
Since we have multiplication we multiply our numbers and add exponents
So
4*9=36
and exponents
3+-5=-2
-2+1=-1
So 36a^-2b^-1
BUTTT because we absolutely CANNOT have negative exponents we put them in the denominator to make them positive so our final answer is
[tex]\frac{36}{a^2b}[/tex]

Factor by grouping. m²s−m²t − ns + nt
Answer:
m²s − m²t − ns + nt = m²(s - t) - n(s - t) =(m² - n)(s - t)A sphere with surface area of 154cm² is fit exactly in cubical box, Use π 22/7
what is the volume of the box A.147
B.154
C.216
D.343
Answer:
Answer :-Surface area of sphere = 4 π r²
154 = 4 × 22/7 × r²
154 = 88/7 × r²
154 × 7/88 = r²
12.25 = r²
3.5 = r
Now
Volume of sphere = 4/3 × π r³
Volume = 4/3 × 22/7 × (3.5)³
Volume = 88/21 × 42.875
Volume = 154 cm³
Volume of sphere = Volume of cube
Volume of cube = 154 cm³

Find the value of x from the given figure:
Answer:
60°
Step-by-step explanation:
2x and x are linear pair,
=> 2x + x = 180
=> 3x = 180
=> x = 180/3
=> x = 60°
=>2x =120°
Answer:
x = 60
Step-by-step explanation:
x + 2x = 180 {linear pair}
Combine like terms
3x = 180
Divide both sides by 3
x = 180/3
x = 60
