Answer:
c = (b+3a)/2
Step-by-step explanation:
<u>Solve for c:</u>
<u>Multiply both sides by abc:</u>
- abc/ac = 2abc/ab - 3abc/bc
- b = 2c - 3a
- b + 3a = 2c
- 2c = b + 3a
- c = (b + 3a)/2
Answer:
1. if x + 5 = 12, then x = 7
:Subtraction property of equality
2. If x + y = 20, and y = 5, then x + 5 = 20.
<u>:Substitution property of equality</u>
3. If 2x3 = 11, then 11 = 2x - 3.
<u>:Symmetric property of equality</u>
Answer: x=8
for every 5 there is 2
so for x=8
there are four 5's in 20
I hope this is good enough:
142475.748 is the answer.
Answer:
