-79 = 7w + 3(4w – 1)
how do i solve this ?

-4 = w OR w = -4

Step-by-step explanation: For this given equation you will have to solve for the variable w. In order to do this you must isolate the variable w.

Step 1: Use the distributive property: -79=7w+3(4w-1)  ( 3 x 4w = 12w and 3 x -1 = -3.

Step 2: Add like terms and whole numbers: -79=7w+12w-3 (  7w + 12w = 19w

Step 3: Use the Addition Property of Equality:3 + -79=19w-3+3 ( 3 + -79 = -76 and -3 + 3 =0

Step 4: Use the division Property of Equality: -76=19w -76 divided by 19 is -4 and 19w divided by 19 is w

Step 5: The -4=w

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50
