Answer:
a = 5
Step-by-step explanation:
3(a+3)+6=30
Subtract 6 from each side
3(a+3)+6-6=30-6
3(a+3) = 24
Divide by 3
3/3(a+3) = 24/3
a+3 = 8
Subtract 3 from each side
a+3-3 = 8-3
a = 5
Answer:
a = 5
Step-by-step explanation:
Apply the distributed property, so it now looks like this: 3a + 9 + 6 = 30Simplify: 3a + 15 = 30Subtract 15 from each side, so it now looks like this: 3a = 15Divide each side by 3 to cancel out the 3 next to a. It should now look like this: a = 5I hope this helps!

Solve for the value of m
Answer:
m = 7
Step-by-step explanation:
The 3 given angles lie on a straight line, thus sum to 180° , then
8m - 4 + 90 + 5m + 3 = 180, that is
13m + 89 = 180 ( subtract 89 from both sides )
13m = 91 ( divide both sides by 13 )
m = 7
find the value of x. PLEASE HELP
I need to show my work.
THANK YOU!!!
==========================================
Work Shown:
The given angles are a linear pair, so they are supplementary.
(1+5x)+(3+3x) = 180
1+5x+3+3x = 180
(5x+3x)+(1+3) = 180
8x+4 = 180
8x+4-4 = 180-4 .... subtract 4 from both sides
8x = 176
8x/8 = 176/8 ..... divide both sides by 8
x = 22
------------
Extra info:
1+5x = 1+5*22 = 1+110 = 111
3+3x = 3+3*22 = 3+66 = 69
111+69 = 180, which helps confirm the answer.

Dan had $10. He bought x pencils, each costing y cents .How much money did Dan have left?
Answer: Unknown...Well, just simplify.
Step-by-step explanation:
Since it says x and y, that is NOT a number. So the real question is, how can we solve the problem without numbers? Well that's pretty simple and easy. Since we don't know the number, we will just have to simplify. With no actual number, simplifying is basically the answer. Unless, you can find out the answer.
Dan has the amount of money left would be 10 - xy which is the form of an expression.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
We have to determine the amount of money Dan has left.
We must only generalize since we don't know the exact quantity. Having no method of solving,
Dan had $10. He bought x pencils, each costing y cents which are given in the question.
quantity of pencils = x and cost of pencil = y
As per the given condition, the required solution would be:
⇒ remaining amount = 10 - quantity of pencils × cost of pencil
⇒ remaining amount = 10 - (x) × (y)
⇒ remaining amount = 10 - xy
Therefore, Dan has the amount of money left would be 10 - xy which is the form of an expression.

Answer:
7.2 pints
Step-by-step explanation:
a) 1 bowl --- 0.3 pints of soup
Since he has 24 bowls,
total amount of soup in the bowls
= 24(0.3)
= 7.2 pints
Thus, Martin put 7.2 pints of soup into the bowls.
At the movies, Hunter bought 3 popcorn and 5 drinks. Each popcorn
costs $0.40 less than a drink. If he spent a total of $24.00, what was the
cost of each popcorn?
Step by step explanation pls!!!!
Answer:
P= $2.75
Step-by-step explanation:
So first we need to create our system of equations
since each popcorn is 0.40 less than each drink we can make the equation:
D - 0.40 = P we can rewrite that as P + 0.40 = D so that we have D by its self.
Next, we create the overall equation:
$24.00 = 3P + 5D
Now plug in D from the first equation into the second equation:
$24.00 = 3P + 5( P + 0.40)
Distribute the five and solve for P:
$24.00 = 3P + 5P + 2
$22.00 = 8P
P = $2.75
Now add 0.40 which would be $3.15 and plug it into the first equation just to make sure that the answer is correct.

Each day for two workweeks (10 days total), George weighs 4 bags from that day’s production. If the average of the means is 14 oz. and the average range is 0.4 oz., what is the lower control limit for an x-bar chart for this process?
a. 13.7084 oz.
b. 13.8768 oz.
c. 14.2916 oz.
d. 12.8000 oz.
e. 13.5908 oz.
Answer:
a. 13.7084 oz.
Step-by-step explanation:
Formula for Lower Control Limit =
(LCL = x-bar - A²R-bar)
x - bar = 14 oz
A2 = 0.729
R - bar = 0.4 oz
= 14 - 0.729 × 0.4
= 14 - 0.2916
= 13.7084oz

Answer:
34
Step-by-step explanation:
10+2=12
12 on both sides=24
5 on both sides=10
10+24=34
The perimeter of the rectangle is 34 for the given sides.
What is the perimeter of the rectangle?The rectangle is defined as a quadrilateral having four sides and the angle suspended by all the sides is equal to 360 degrees. The perimeter is the sum of all the sides of the rectangle.
Given that the two sides of the rectangle are 5 and x + 2. The value of x is 10.
The perimeter of the rectangle will be calculated as:-
L = 10+2=12
12 on both sides=24
5 on both sides=10
Perimeter = 10+24=34

Answer:
Let x=the smaller integer.
Let x+1+ the larger integer.

(x+x)+1=173
2x+1=173
2x+1-1=173-1 (substract 1 from both sides)

A cylinder has a base diameter of 4 centimeters and a height of 4 centimeters. What is its volume in cubic centimeters, to the nearest tenths place
Answer:
50.3 cm³
Step-by-step explanation:
Use the cylinder volume formula:
V = [tex]\pi[/tex]r²h, where r is the radius and h is the height.
Since the radius is half of the diameter, and the cylinder has a diameter of 4 cm, this means the radius is 2 cm.
Plug in the radius and height into the equation:
V = [tex]\pi[/tex]r²h
V = [tex]\pi[/tex](2²)(4)
V = 16[tex]\pi[/tex]
V = 50.3 cm³
Answer:
50.3 cm³
Step-by-step explanation:
Use the cylinder volume formula:
V = r²h, where r is the radius and h is the height.
Since the radius is half of the diameter, and the cylinder has a diameter of 4 cm, this means the radius is 2 cm.
Plug in the radius and height into the equation:
V = r²h
V = (2²)(4)
V = 16
V = 50.3 cm³

A scientist needs 10 liters of a 20% acid solution for an experiment, but she has only a 5% solution and a 40% solution. To the nearest tenth of a liter, about how many liters of the 5% and the 40% solutions should she mix to get the solution she needs? Write and slove an equation to match the situation. :
Equation:________________________
Solution:____ liters of 5% and _____ liters of 40%
Answer:
Equation: X × 0.4 + (10 - X)×0.05 = 10 × 0.2
Solution: 5.71 liters of 5% and 4.29 liters 40%
Step-by-step explanation:
The volume of the 20% acid solution the scientist needs = 10 liters
The concentration of the solution she has = 5% and 40%
Therefore, we have;
X volume of the 40% solution is mixed with 10 - X volume of the 5% solution, to obtain 10 liters of the 20% solution
Therefore, we have;
Equation: X × 0.4 + (10 - X)×0.05 = 10 × 0.2
0.4·X + 0.5 - 0.05·X = 2
0.35·X = 2 - 0.5 = 1.5
X = 1.5/0.35 = 30/7
∴ The volume of the 40% solution = 30/7 liters ≈ 4.29 liters
The volume of the 5% solution = 10 - X = 10 - 30/7 = 40/7 liters ≈ 5.71 liters
Therefore, we have;
5.71 liters of 5% solution and 4.29 liters 40% solution.
