Gertrude has 83.21 centimeters of wire. She uses 2 pieces of the wire. Each piece she uses is 15.12 centimeters long. What is the length of
the remaining wire, rounded to the nearest tenth of a centimeter?
(Only round your final answer.)

53 centimeters

Step-by-step explanation:

she uses 30.24 wire so subtract that from 83.21 then round that answer which was 52.97 to 53

40 x 50 = 2000

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
