Answer:
x = 9
Step-by-step explanation:
You have to use the Secant Segment theorem:
AB * AC = AD * AE
This means that the external piece of the secant times the whole secant for one is equal to the external piece of the secant times the whole secant for the other.
Now, setup an equation:
8(x + 8) = 4(30 + 4)
Simplify:
8x + 64 = 120 + 16
8x = 72
x = 9
Answer:
The correct answer to this problem is the third statement which is "Alexia completed 20 math problems and 10 science problem". The following conditions are stated in the problem:
Alexia can answer 3 minutes on each math problem
Alexia can answer 4 minutes on each science problem
She worked more than 60 minutes
We have the inequality 3x + 4y > 60 where x represents the total number of math problem while y represents the total number of the science problem.
in our answer, we have x=20and y=10
3*20 + 4*10 > 60
60 + 40 > 60
100 > 60
