To solve this problem, you have to use a proportion:
7/20 = x/100
After setting up the proportion, you have to cross multiply:
20x=700
Now, solve the equation by dividing by 20 on both sides:
x=35
So Charles has 35 laps left.
Answer:
480
Step-by-step explanation:
1/5 of 400 = 1/5 * 400 = 80
increase 400 by 80 = 480
The first one is 0.27, Second one is 0.12, third one is 2 times people live per year, and the last one is 0.02
F(4) = -4(4) - 3 = -16 - 3 = -19
answer
f(4) = -19
g(-4) = 2(-4)^2 - 3(-4) = 2(16) + 12 = 32 + 12 = 44
answer
g(-4) = 44
