Solve this problem on paper using all four steps. Ted weighs twice as much as Julie. Mike weighs three times as much as Julle. Together, Ted, Mike, and Julie weigh 210
lbs. What is the weight of each person?

30

step-by-step explanation:

times by times

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
