Solve using double substitution y=x-7 y=-2x+8

Ivenika [448]

Answer:

(5, -2)

Step-by-step explanation:

x - 7 = -2x + 8

add 2x to both sides

x - 7 + 2x = -2x + 8 + 2x

3x - 7 = 8

Add 7 to both sides

3x - 7 + 7 = 8 + 7

3x = 15

x = 5

y = 5 - 7

y = -2

Solution (5, -2)

stiv31 [10]

Answer: $5

Step-by-step explanation:

For every $3 raised by basketball players, football players would raise $2.50.

If basketball players raised $6 therefore, we can use direct proportion to find out what football players raised:

3 : 2.50

6 : x

Cross multiply:

3x = 15

x = 15 / 3

x = 5

Football players raised $5.
