Answer
42
Step-by-step explanation:
Let x be Chris's age before, x+35 be Chris's age now.
2(x+35) = 35+7x
2x+70 = 35 +7x
35=5x
7=x
7+35=42

Answer:
2640 feet
Step-by-step explanation:
Let's make a proportion using this:
feet/seconds=feet/seconds
We know the car travels 88 feet in 2 seconds.
88/2=feet/seconds
We don't know how many feet the car can travel in 1 minute (which is equal to 60 seconds).So, the car travels x feet in 60 seconds.
88/2=x/60
We want to solve for x. To do this, we have to get x by itself. x is being divided by 60. Multiply both sides by 60, because multiplication is the opposite of division.
60*88/2=x/60*60
The 60s on the right will cancel, so we are left with
60*88/2=x
60*44=x
2640=x
The car can travel 2640 feet in 1 minute.
2 X { 6 + [ 12 divided ( 3 + 1 ) ] } - 1
3 + 1 = 4
12 divided by 4 is 3
2 X { 6 + [ 3 ] } - 1
6 + 3 = 9
2 X { 9 } - 1
9 X 2 = 18
18 - 1 = 17!
17 is the answer
