Step-by-step explanation:
3 - 2(b - 2) = 2 - 7b
To solve this first distribute -2 to (b - 2)
3 + (-2b + (-2) x -2) = 2 - 7b
when we simplify this it becomes:
3 + (-2b + 4) = 2 - 7b
We take (-2b + 4) out of the parenthesis:
3 - 2b + 4 = 2 - 7b
Now simplify again.
7 - 2b = 2 - 7b
Now send all the b's to one side and constants on the other.
7 - 2 = -7b +2b
5 = 5b
b = 1
Answer:
choice b
Step-by-step explanation:
3.49
____ = 0.1396 ≈ 0.14 or 14 cents per ounce
25
4.79
____ = 0.10644444 ≈ 0.11 or 11 cents per ounce
45
35% of 120 is 42. (42/32 then multiply that by 100)
92% of 125 is 115. (115/92 then multiply that by 100)
12/36 = x/100
Then cross multiply
1200 = 36x
Divide by 36
x = 33.33
Can’t sell 0.33 of an appliance, so your answer is 33.
