I got B but I'll show you how I got that answer.

Let's look at AB and BC. AB = 3 and BC = 4.
3/4 = 0.75

On the triangle, AB = 90. And BC = 10x - 20. We need to solve for x and prove that AB/BC = 0.75.

Let's start with Choice A.

10(11) - 20 = 90.

AB = 90
BC = 90.

90/90 = 1. It doesn't equal 0.75. Meaning this answer is wrong.

Now let's look at Choice B.

10(14) - 20 = 120.

AB = 90
BC = 120

90/120 = 0.75

So, 3:4 = 90:120 making Choice B the correct Answer. Let me know if this is correct

rodney needs $90 to buy a fish tank. he has saved $35 and plans to work as a babysitter to earn $5 per hour. which inequality sh
kykrilka [37]
N = number of hours.

$5 per hour, total = 5*n = $5n

Since $35 has been saved. 

The amount saved plus the amount got from baby sitting should be greater or equal to the $90 cost.

5n + 35 ≥ 90

5n ≥ 90 -35

5n ≥ 55

n ≥ 55/5

n ≥ 11

So Rodney should baby sit for at least 11 hours, that is 11 and above.
