You have a summer job detailing cars. You charge $5 to wash a car, $25 to wax a car, and $2 to vacuum a car. What algebraic expression models the total amount you can earn? If you wash 8 cars, wax 2 cars, and vacuum 6 cars, how much will you earn in all?
5x+25x+2x, $102
Step-by-step explanation:
5x+25x+2x
5(8)=40
25(2)=50
2(6)=12
add what's behind the equal signs to get $102 in all
I need help with part 2 please
Answer:
$65
Step-by-step explanation:
So we already determined that the total cost C to drive m miles is:
[tex]C=0.25m+40[/tex]
And we want to find the total cost of driving 100 miles.
So, substitute 100 for m and solve for C:
[tex]C=0.25(100)+40[/tex]
Multiply:
[tex]C=25+40[/tex]
Add:
[tex]C=\$ 65[/tex]
Therefore, it will cost $65 to drive 100 miles.
Find the value of x.
Answer:
x=20°
Step-by-step explanation:
This is actually simpler than it seems. Try redrawing (or maybe just imagine) that the only inscribed angle is x with the two lines going to the 40°. If we let 40°=θ, then: x=θ/2
This is actually true for any situation with inscribed angles, so you could use this to find w, y, and z as well.
Anyways x=(40°)/2=20°, so x=20°
please help :) Find the unknown length y in the following pair of similar triangles. y= ?
Answer:
Y should equal to 4.5
Step-by-step explanation:
Since they are similar triangles and each of the measurements on the second triangle are divided by two you would do the same for y
Solve 20 - x/3 = x/2 , put the number only in the box.
Answer:
x = 24Step-by-step explanation:
[tex]20 - \frac{x}{3} = \frac{x}{2} [/tex]
Multiply through by the LCM that's 6 in order to eliminate the fraction
That's
[tex]6 \times 20 - 6 \times \frac{x}{3} = 6 \times \frac{x}{2} \\ 120 - 2x = 3x[/tex]
Using the addition property add 2x to both sides of the equation
That's
[tex]3x + 2x = 120 + 2x - 2x \\ 5x = 120[/tex]
Divide both sides by 5
[tex] \frac{5x}{5} = \frac{120}{5} [/tex]
We have the final answer as
x = 24Hope this helps you
Answer:
X=24
Step-by-step explanation:
20=x/2+x/3
20=1/2x +1/3x
20=5/6x
20÷5/6=x
X=24
A school bus requires 40 liters of fuel per week. If your school district runs 5,000 school buses, how many liters of fuel will the buses consume in 52 weeks? A. 15 million liters B. 10 million liters C. 10.4 million liters D. 200 million liters
Answer:
C. 10.4 million liters.
Step-by-step explanation:
1. First, you want to create an equation to help you solve this. You know that there are 5,000 school buses and they use 40 liters of fuel per week. So, you know that 5,000 · 40x would be the amount of fuel for x weeks (where x is the number of weeks).
2. To figure out how many liters would be used in 52 weeks, simply put 52 in for x. So, the expression is 5,000·40(52).
3. Multiply 40(52) to get 2,080. Your expression now looks like this: 5,000·2,080
4. Multiply 5,000(2,080) to get your answer of 10,400,000 liters.

insert two numbers between 54 and 2 so that the four numbers are in geometric sequence.
Answer:
2,6,18,54
How I got this answer:
Each term after the first is found by multiplying by a fixed, non-zero number called a common ratio.
step by step:
2×3=6
6×3=18
18×3=54
The common ratio is 3.
Find the probability for one roll of a number cube.
P(number greater than or equal to 7)
A. 1/7
B. 0
C. 1/6
D. 1
The only possible outcomes on a standard number cube (aka a die or dice) are {1,2,3,4,5,6}
It is not possible to roll a 7 or larger, so we say the probability is 0. A probability of 0 means "impossible".
The measure of an angle is 89 times the measure of its supplementary angle. What is the measure of each angle
Answer:
2 and 178
Step-by-step explanation:
If we take an instance of a number 'x', according to the question we find that x+x*89=180(Because they are complementary)
We get, = 89x+x=180
=> 90x=180
=> x=180/90
=> x =2
So, we found that x=2 , hence the other angle is going to be 2*89=178
This is correct as 2+178=180(as they are supplementary to each other)
Hope this answer helps, Please mark me as brainliest, Thank you!
Two points (p, q) on a linear supply function are ($2.55, 98,000) and ($6, 195,500).
⦁ Determine the supply function q = f(p).
⦁ What price would result in supplier offering 145,000 units for sale?
⦁ Interpret the slope of the function.
⦁ Determine the p intercept.
⦁ Sketch f(p)
Answer:
q ≈ 28270p +25935$4.21 will give a supply of 145,000slope is the supply increase per dollar of pricep-intercept is about -$0.92a graph is attachedStep-by-step explanation:
The two-point form of the equation of a line is useful for this.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
q = (195500 -98000)/(6.00 -2.55)(p -2.55) +98000
q = 97500/3.45(p -2.55) +98000
q ≈ 28269.9p +25934.8
__
For a supply of 145000, the price would need to be ...
145000 = 28269.9p +25934.8
119065 = 28270p
119065/28270 = p = 4.21
A price of $4.21 will result in a supply of $145,000.
__
The slope is the additional amount supplied for each dollar increase in price.
__
The price value that results in a supply of zero is ...
0 = 28270p +25935
-25935 = 28270p
-25935/28270 = p ≈ -0.92
The p-intercept is about -$0.92.

if f(x)=2x-1 and g(x)=x^2-3x-2, find (f+g)(x)
Answer: (f+g)(x)=x²-x-3
Step-by-step explanation:
(f+g)(x) means f(x)+g(x). Since we are given f(x) and g(x), we can add them together.
(f+g)(x)=2x-1+x²-3x-2 [combine like terms]
(f+g)(x)=x²-x-3
Now, we know that (f+g)(x)=x²-x-3.
