Answer:

Hi!

Alrighty here we go:

2(9+x)=-5(4-x)

18+2x=-20+5x

Now combine like terms

+20+18+2x=-20+20+5x

38+2x=5x

38+2x-2x=5x-2x

38=3x

x= 38/3

Hope this helped!

Maria and victor each play a video game. The ratio of the number of points Maria scores to the number of points victor scores is
zvonat [6]

Answer:

Step-by-step explanation:

I don't know what a tape diagram is but I can give you the equation and the answer.

Let Victor have x points

Let Maria have y points

y = x + 424

y/x = 5/3                     Cross multiply

3y = 5x                       Divide by 3

y = 5x/3                      I Could have just multiplied by x

y = x + 424

5x/3 = x + 424           Multiply both sides by 3

5x = 3x + 1272           Subtract 3x from both sides.

5x-3x = 1272              Combine the left.

2x = 1272                    Divide by 2

2x/2 = 1272/2

x = 636

Victor Scored 636 points

Maria Scored 636 + 424 = 1060

Heather drove 265 miles using 10 gallons of gas. At this rate, how many gallons of gas would she need to drive 424 miles?
slava [35]

Answer:

Step-by-step explanation:

Next bit of info that we have is 424 miles. Miles go on the numerator, and gallons, which we will call "x" will go on the denominator. It should be set up like this: 265/10 = 424/x Once you cross multiply you should get 265x=4240. Divide 265 by both sides and the answer is 16 gallons.  Sorry if its wrong
