Ben and Carla each have $10 to spend. They purchase 6 packs of baseball cards for $0.79 each and two balls that cost $5.95 each.

if they split the cost evenly, how much change will they receive?
Expression: 10 - 6(0.79) + 2(5.95) /2
First step: Multiply the parentheses.
Second step: Rewrite the equation: 10 - 4.47 + 11.90 /2
Third step: Add 4.47 and 11.90. Then rewrite the expression.
Expression: 10 - 16.64/2
Fourth step: Divide 16.64 and 2.
Rewrite the expression: 10 - 8.32.
Ben and Carla will each have $1.68 left in change after their purchase.
Hope I helped!

Find the value of the variable. Then find the angle measures of the polygon.
Anvisha [2.4K]
First set up the equation (sum of the angles is 180)

2x + 2(x-1) + (5x +2) = 180

distribute:
2x + 2x -2 + 5x +2 = 180

combine like terms:
9x = 180
solve for x:

x = 20

SO:

2x° = 2(20) = 40 degrees
2(x-1)° = 2(20) - 2 = 40 - 2 = 38 degrees
5x + 2°= 5(20) + 2 = 100 + 2=102 degrees

check: 40 + 38 + 102 = 180
