What is the ratio of 30 inches to 2 feet?

30:24, or 5:4

Step-by-step explanation:

To find this answer, we should convert 2 feet to inches, as it's an easier conversion than 30 inches to feet. There are 12 inches in one foot, so we would multiply 2 by 12 to find our conversion.

So, our ratio would be in its unsimplified form. In order to simplify efficiently, we should find our GCF, or greatest common factor. In this situation, our GCF would be 6, so let's divide both numbers by that.

So, simplified, our ratio would be 5 inches to 4 inches, or 5:4.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
