Step-by-step explanation:
A. 1.13 and B is 1.37
The water bill was 1/5 of the total, so was 0.2*$540 = $108.
Answer:
Step-by-step explanation:
18.4 + 8w = 6(-4.6 + 9w)
18.4 + 8w = (-4.6 * 6 + 9w * 6)
18.4 + 8w = (-27.6 + 54w)
18.4 + 8w + -54w = -27.6 + 54w + -54w
18.4 + -46w = -27.6 + 54w + -54w
18.4 + -18.4 + -46w = -27.6 + -18.4
Combine like terms: 18.4 + -18.4 = 0.0
0.0 + -46w = -27.6 + -18.4
-46w = -27.6 + -18.4
-27.6 + -18.4 = -46
-46w = -46
w = 1
Simplifying
w = 1
Answer:
For this equation to be true, a must = 13 and b must = 10 + 2i.
Step-by-step explanation:
First combine the numerators: 3 + 5 + 2i + 2, or 10 + 2i.
Next, multiply the denominators: 4 + 9 = 13
Then rewrite the original equation as:
10 + 2i a
---------- * ---- = 1
13 b
For this equation to be true, a must = 13 and b must = 10 + 2i.
