On a science test, students earn 5 points for each correct answer and lose 2 points for each incorrect answer. If there are 56 questions on the test, a student’s score is shown by the expression 5(56−w)−2w, where w represents the number of wrong answers. Pete says that the expression 7(40−w) could also be used. Is Pete correct? Why or why not? Show your work.

You earns $35 for washing 7 cars. How much do you earn for washing 4 cars? *

Answers

The answer is $20.

Lets solve for x,being how much we earned.

x=?

35 divided by 7 is 5.

Now lets multiply by 4.

5x4=20.

35÷7=55×4=20

So your answer is 20

Hope this helps :)

Answer:

You will earn $20 by washing 4 cars.

Step-by-step explanation:

in the question it states the earning by washing seven cars is $35.

So, the earning for washing four cars is given by:

= 4/7  x 45

so we Simplify the above expression.

= 140/7

= $20

so in conclusion we would get $20 for washing four cars.

Seth's father is thinking of buying his son a six-month movie pass for $25. With the pass, movies cost $2
each.
Write a linear equation to represent the total cost spent of Seth seeing movies for the next 6 months.

Answers

Answer:   y = 2x+25

x = number of movies

y = total cost

========================================================

Explanation:

The starting cost is $25, which is the amount spent even if no movies are watched.

Since x is the number of movies, and each costs $2, this means Seth spends an extra 2x dollars more on top of the $25 already spent.

In total, the cost is 2x+25 which leads to y = 2x+25

This linear equation is in slope intercept form y = mx+b

m = 2 = slope

b = 25 = y intercept

Y=2x + 25 is the answer

What is the area of quadrilateral DYES?

Answers

Answer:

16.97

Step-by-step explanation:

you need to find the length of DY (the hypotenuse of one of the triangles), and to do that, you need to find the length of CY, so subtract AB (which is 1) from AY (which is 5) and you are left with 4. then use the Pythagorean theorem to solve for DY. [tex]1^{2}[/tex] + [tex]4^{2}[/tex] = [tex]17^{2}[/tex]. [tex]\sqrt{17}[/tex] = 4.12 (rounded to the nearest hundredth). The last step is to solve for area, or length times height. The quadrilateral has equal side lengths, so the equation is

4.12 × 4.12 which equals 16.97

A row of lockers has a length of 72 inches and a width of 60 inches. Gabrielle made a scale drawing of the row of lockers using a scale of 1/2 centimeters = 6 inches.

Answers

Answer:

Length- 6 centimeters.  Width- 5 centimeters

Step-by-step explanation:

Ok, so 1/2 centimeter = 6 inches

let’s first take the length witch is 72 inches and divide that by 6. Then, since it half a centimeter, divide in half.

72/6 = 12     12/2 = 6 centimeters

Next is the width. Now we the same thing as the length. Take 60 and divide by 6 then divide in half.

69/6 = 10.    10/2 = 5 centimeters

In summary, The scale drawing has length of  6 centimeters and a width of 5 centimeters.

The car can hold up to 4 passengers. Write an inequality for the number of passengers that could be in the car at any given time.

Answers

Answer:

The equation relating the number of cars to the number of passengers is p = 4n

Step-by-step explanation:

Given that certain type of car has room for 4 passengers

To find: write an equation relating the number of cars to the number of passengers

Let "n" be the number of cars

Let "p" be the number of passengers

From given information,

Car has room for 4 passengers. Therefore, we can frame,

number of passengers = 4 ( number of cars )

p = 4 (n)

p = 4n

Thus the equation relating the number of cars to the number of passengers is p = 4n
