Suppose that 15 inches of wire costs 45 cents. At the same rate, how many inches of wire can be bought for 27 cents?

9

Step-by-step explanation:

If 15 inches=45 ..divide 45 by 15 which is equal to 3. So 27 divided by 3 = 9 inches of wire

9 inches

Step-by-step explanation:

1 cent : 45/15 = 3 inches

27 cents : 27/3 = 9 inches

answer: the correct one is a

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
