To raise funds for uniforms and travel expenses, the soccer team is holding a car wash in a part of town with a lot of car and truck traffic. The team spent $90 on supplies like sponges and soap.
They plan to charge $10 per car and $20 per truck. Their goal is to raise $460.

How many cars do they have to wash if they washed the following numbers of trucks?
1.4 trucks
2. 15 trucks
3.21 trucks
4. 27 trucks
5. t trucks

1.38 3.16 3.9 4.0

Step-by-step explanation:

Step 1: Take number of truck multiply $20, get answer(s).

Step 2: subtract answer #1 subtract from $460

Step 3. Divide answer step 2 by $10 car

4: your answer

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
