Answer:
Solve for each for X.
Step-by-step explanation:
A. 7+2ax=13
1a. Subtract 7 from both sides, 2ax=6
2a. Divide both sides by 2, ax=3
3a. Divide both sides by a, x=3/a
B. -ax-20=-14
1b. flip the signs, ax+20=14
2b. subtract 20 on both sides, ax=-6
3b. divide both sides by a, x=-6/a
C. 4= (6/a)x+5
1c. Multiply both sides by a, 4a=6x+5a
2c. Subtract 5a from both sides, -a=6x
3c. Divide both sides by -1, a=-6x
-9x+16
-3x+7+-6x+9=-9x+16
-3-6= (tecnectly adding but put negative sign with ur answer!)
7+9=16
Put together and Done!
Hope helps :D
4 2/3 = 14/3
15 = 15/1
14/3 * 15/1 = 14*15=210, 3*1 = 3
210/3 = 70
answer is 70
75.36 inches
c=2pir or 2(12)pi 24pi=around 75.36
803.8 in
