Answer:
x = 5 
Step-by-step explanation:
Hi there!
So, to answer this problem, I'll use the reverse method.
31 - 4 = 27,
So how many times, can 5 go into 27?
The closest factor of 5 to 27 is 25.
5 can go in to 27, 5 times.
Continuing on, there is a 2 left over, so the answer to your question is
x = 5
5 · 5 - 4 = 31
Let me know if I am incorrect and I will attempt to find the right answer for you.

Answer:
150/250
Step-by-step explanation:
24/42, 75/135, 150/250, and 75/150 I believe is what you're asking. We know 75/135 is better than 75/150 so 75/150 is out of the equation. If we multiple 75/135 by 2 we get 150/270 which is more than 150/250, so 75/135 is out of the equation. Now to compare 24/42 and 150/250 we can divide their fractions, if we divide 24/42 we get 0.57, so 57%. If we did 150/250 we get 0.6 or 60%. So 150/250 is the best score.
We are given with
a1 = 2
r = 4
These are components of a geometric series. The first term is 2 and the common ratio is 4. To get the first six terms, we use the formula:
an = a1 r^(n-1)
a1 = 2 (4)^(1-1) = 2
a2 = 2 (4)^(2-1) = 8
a3 = 2 (4)^(3-1) = 32
a4 = 2 (4)^(4-1) = 128
a5 = 2 (4)^(5-1) = 512
a6 = 2 (4)^(6-1) = 2048
