Answer is c.
t = 0.5(d+h)
multiply both sides by 2 to cancel out the 0.5.
2t = d+h
2t - d = h
12/3 = x/8
Cross multiply
3x = 96
Eliminate
3x/3 = 96/3
x = 32
Answer: B.
Step-by-step explanation:
the sum of 5 x 10 with exponent 4 would be 50,000.
multiply that by 12 and it would be 600,000, which is also equal to
6 x 10 with exponent 5.
hope this helps :)
