find the value of x
The answer is 40.
I need to show my work
Answers
Answer:
(2x+7)° + (5x+4)° + 69° = 360°
=> 2x + 7 + 5x + 4 + 69 = 360
=> 7x + 80 = 360
=> 7x = 360 – 80
=> x = 280/7
=> x = 40
Answer:
x=40
Step-by-step explanation:
(2x+7)*+(5x+4)*+69*=360* (360* because its a circle)
7x+80=360 (combine like terms)
- 80 -80 (minus 80 both sides)
7x=280 (divide 7 both sides)
x=40

Answer:
7) (f+g)(x) = 4^x +5x -5
8) (f-g)(x) = 4^x +x +5
Step-by-step explanation:
7) add the two expressions.
(f+g)(x) = f(x) +g(x) = (4^x +3x) +(2x -5)
(f+g)(x) = 4^x +5x -5
__
8) subtract g(x) from f(x).
(f-g)(x) = f(x) -g(x) = (4^x +3x) -(2x -5) = 4^x +3x -2x +5
(f-g)(x) = 4^x +x +5

Which of these relations is a function?
Answers
Why is this? This is the only relation that passes the vertical line test.
The other choices have situations where we can draw a single straight vertical line through more than one point on the blue curve. That means the graph fails the vertical line test and we do not have a function.
For a function to be possible, any x input must lead to exactly one y output.

B. (4, 8, 12) D. (12, 6, 8)
Answers
Answer: C. (8, 16, 4)
Step-by-step explanation:
Given the following:
Let:
Trucks = T ; Cars = C ; SUVs = S
T =0.5(C + S) - 2 - - - (1)
C = 2T - - - (2)
T + C + S = 28 - - - (3)
T = 0.5(2T + S) - 2
T = T + 0.5S - 2
0 = 0.5S - 2
0.5S = 2
S = 2/0.5
S = 4
From T + C + S = 28
C = 2 T ; S = 4
T + 2T + 4 = 28
3T = 28 - 4
3T = 24
T = 24/3
T = 8
From T + C + S = 28
8 + C + 4 = 28
12 + C = 28
C = 28 - 12
C = 16
Hence, (T, C, S) = (8, 16, 4)

Solve 4x – 2(x + 1) = 3x + 10.
Answers
Answer:
x=-12
Step-by-step explanation:
4x−2(x+1)=3x+10
Step 1: Simplify both sides of the equation.
4x−2(x+1)=3x+10
4x+(−2)(x)+(−2)(1)=3x+10(Distribute)
4x+−2x+−2=3x+10
(4x+−2x)+(−2)=3x+10(Combine Like Terms)
2x+−2=3x+10
2x−2=3x+10
Step 2: Subtract 3x from both sides.
2x−2−3x=3x+10−3x
−x−2=10
Step 3: Add 2 to both sides.
−x−2+2=10+2
−x=12
Step 4: Divide both sides by -1.
−x/−1=12/−1
x=−12
Answer:
x=−12
Answer:
x=-12
Step-by-step explanation:
4x-2x-2=3x+10
2x-2=3x+10
2x-2+2=3x+10+2
2x=3x+12
2x-3x=3x+12-3x
-x=12
-x/-1 = 12/-1

A total of 4500 tickets to a concert were sold and the price for each ticket was either $59 or $85. If the
amount collected was $291, 500, how many tickets were sold at each price?
O (35, 10)
O (3500, 1000)
O (1000, 2200)
O (3000, 1500)
Answers
Answer:
3500 tickets were sold at $59
1000 tickets were sold at $85
(3500, 1000)
Step-by-step explanation:
x + y = 4500
59x + 85y = 291500
x + y = 4500
x = 4500 - y
59(4500 - y) + 85y = 291500
265500 - 59y + 85y = 291500
265500 + 26y = 291500
26y = 26000
y = 1000
x + y = 4500
x + 1000 = 4500
x = 3500
Check:
x + y = 4500
3500 + 1000 = 4500
4500 = 4500
59x + 85y = 291500
59(3500) + 85(1000) = 291500
206500 + 85000 = 291500
291500 = 291500

Two angles are supplementary. If one angle measures twice the other, and the number of degrees in the smaller angle.
Answers
Answer:
60 Degrees
Step-by-step explanation:
Supplementary means it equals 180 together, so you divide it by 3 because the one is twice as big and you take the smaller answer
[tex]\frac{180}{3} =60[/tex]
Small and large angle are 60° and 120°.
Given that;
Angles are supplementary
Computation:
Assume;
Smaller angle = a
So,
Large angle = 2a
So,
In supplementary
a + b = 180
a + 2a = 180
3a = 180
a = 60
Smaller angle = 60°
Large angle = 2(60)
Large angle = 180°

Step-by-step explanation:
Hi there!
You'll notice that this equation is a quadratic. When graphed, this equation looks like a parabola that crosses the x-axis at two points, which can be written as ordered pairs with an x value and a y value.
We know that both of these points will have a y value of 0, but we don't know what the x values of the points are—these are what we want to find.
(Check out the graphing program Desmos—type in your equation and it will graph it out for you.)
Notice that your equation follows this structure:
[tex]ax^2+bx+c=0[/tex]
In our case,
[tex]a=3\\b=-5\\c=-2[/tex]
We can plug our values of a, b, and c into the quadratic equation to find the two x values.
I've attached a picture of my work. At the top is the quadratic equation. I substituted our values in and solved.
You'll notice that the answer I ended up with has a ± symbol. We have to simplify this down two different ways to get our two answers: once using the plus sign, once using the minus sign. This will give us two different values for x.
We'll start with the plus sign:
[tex]\frac{5+7}{6} \\=2[/tex]
So: one of our x values is 2.
Now the minus:
[tex]\frac{5-7}{6} \\=-\frac{1}{3}[/tex]
Our other x value is -1/3.
You can check to make sure these answers work by plugging them back into the original equation for x. If they work, the left side of the equation should boil down to 0.
Let me know if you have any other questions! Best of luck with getting caught up in Algebra!

She can read 216 words per minute, because 72 times One-third is equal to 216.
Answers
Answer:
The answer is
"She can read 216 words per minute because 72 divided by One-third is equal to 216."
Step-by-step explanation:
Given the statement
Susan can read 72 words in One-third of a minute ....pause
Whats is one-third of a minute
it is expressed as 1/3*60=20sec
so Susan can read 72 words in 20 second
this means that in a minute she can read
72+72+72 words= 216 word since 20sec*3 is 1 minute
alternatively
[tex]=\frac{72}{\frac{1}{3} }[/tex]
we then multiply 73 with the inverse of the denominator
