Answer:
35 red marbles
Step-by-step explanation:
So we can put the different color marbles in a ratio. So 7:2:11. If we add all of those up we get 20. We do 100/20 to get 5. Each number in the ratio is equivalent to 5 marbles. Then we do 7*5 to get 35. We can check our work by doing, (7*5) + (2*5) + (11*5) = 100. And it does equal 100 so the answer is correct.
F^1(x)=2x-16 To find the interverse interchange the variable and solve for y
Use proportions and use letters for unknown measurements

2.e
3.8+10(x+3)+x
8+10x+30+x
11x=-30-8
x=38+11x
