Carmen has a piece of wood that measures 8 1/2 inches in length. Lucia has a piece of wood that is 1 5/8 longer than Carmens. How long is Lucias piece of wood?

13 13/16 inches

the length of Lucia's piece of wood is 10 1/8 inches

Step-by-step explanation:

Carmen has a piece of wood that measures 8 1/2 inches in length. Converting 8 1/2 inches to improper fraction, it becomes 17/2 inches.

Lucia has a piece of wood that is 1 5/8 longer than Carmens. Converting 1 5/8 inches to improper fraction, it becomes 13/8 inches. This means that the length of Lucia's piece of wood would be

17/2 + 13/8 = (68 + 13)/8 = 81/8 inches.

Converting to mixed fraction, it becomes

10 1/8 inches

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
