"of" means to multiply.
20% * 60
= 0.2 * 60 (since % means divide by 100)
= 12
The answer is 2.67 seconds per second when rounded but 2.66666...
4,000,000 is 3,567,194 rounded (-:
2 x length + 2 x width = perimeter.
2(2s-5) + 2(4s-13) = 108
Simplify:
4s-10 + 8s-26 = 108
Combine like terms:
12s - 36 = 108
Add 36 to both sides:
12s = 144
Divide both sides by 12:
s = 144/12
s = 12
Now replace s with 12 in each equation:
2(12) - 5 = 24-5 = 19
4(12) - 13 = 48-13 = 35
The answer is d. 35,35, 19,19
