Answer:
identity property
Step-by-step explanation:
8x+ 18 + 3x-3 = 180 straight line
combine like terms
11x+15 = 180
subtract 15 from each side
11x = 165
divide by 11
x = 15
<rsu = 8x+18
= 8*15+18 = 138
< ust = 3x-3
= 3*15-3 = 42
Each bag has 3.5 pounds
they sell 45 bags a day
in one day the sell 45 x 3.5 = 157,5 pounds of apples
in one week (7 days) they sell 7 x 157,5 = 1102,5 pounds of apples
Step-by-step explanation:
Let m = man's age right now
d = daughter's age right now
m-2 = 6(d-2) => m = 6d -12 +2 = 6d-10
m+18 = 2(d+18) => m = 2d+36-18 = 2d+18
6d-10 = 2d+18
4d = 28
d = 7
m = 32
