The Middle Grades Math Club needs to raise money for its spring trip to Washington, D.C., and for its Valentine’s Day dance. The
Elena L [17]

A.

Cars            Amount

0 cars          $-117.50

1 car             $-113.50

2 cars          $-109.50

3 cars           $-106.50

4 cars           $-102.50

10 cars          $-77.50

50 cars         $82.50

100 cars        $282.50

I do not know what graph you have but, you can see how much money you will make because it will form a straight line on the graph. As long as you continue the line, you will be able to see how many cars you have to clean to make a certain amount of money. Same is for the table.

B.

The change in the amount of money earned with each car is $4.00

The change on the graph is shown by the increasing slope.

C.

The number of cars that need to be washed can be seen by using the formula y=4x-117.5

The information from part a and b is used to show that there is a constant change (slope) and that more money is made by washing more cars.

3. The members need to wash 30 cars (rounded up from 29.375) to break even.

4.  The members would have to wash 249 cars (rounded from 248.125) to fund their Washington trip.

The members would have to wash 117 cars (116.875) to fund their Valentine's Day Dance.

5. They would have to wash 366 cars.

Realistic

This can be realistic if there are a lot of members in the Math Club and if they set up in a good location. It will be successful.

Not Realistic

This is not realistic because there are many other factors that need to be taken into consideration. There might not be enough cars or people that are willing to get their car cleaned by these students. There are other supplies that they might need to buy and more.

I need help, please. PLEASE, I NEED IT FAST.
Amiraneli [1.4K]

Answer:

Hint: x is a negative number.

Step-by-step explanation:

The equation is x + 12 = -6 and you are trying to find x. The easiest way to solve this equation is by first subtracting 12 from both sides. It would look like x + 12 - 12 = -6 - 12. Since positive 12 and negative 12 are opposite and equal, they cancel each other out. This can be drawn as well into circles and crossed out for every positive circle with a negative circle. As for -6 and -12, you can use the same method of drawing circles, (trust me they can be very helpful, especially for people like me who need to see it visually before getting a hang of it). Since both are negatives, you would have to add them together and that would give you x.

(Please reply if you still have questions. :) Have a wonderful day)

Molodets [167]

The baby Komodo dragon = 1 3/4 feet.

The adult Komodo is 7 times longer than the baby dragon.

Multiply the two numbers together

7 x 1 3/4 = 7 x 1.75 = 12.25

12.25 is how long the adult Komodo dragon, or 12 1/4

hope this helps

What is s squared +2x-35 factor
Evgen [1.6K]
X^2 + 2x - 35

(a x b) = -35
(a + b) = 2

(7 x -5) = -35
(7 + -5) = 2

Plug them in: 

x^2 - 5x + 7x -35
x(x - 5) + 7(x - 5)

Therefore, you can conclude that our final answer is...

(x + 7)(x - 5)

If you have any questions or do not understand, comment below my answer. :)
