1128 feet = 1128/5280 miles
it travels at 1128/5280 miles per second
to convert to miles / hour we multiply by 3600
so speed of the bullet = (1128 * 3600) / 5280 = 769.1 mph to nearest tenth.
Answer:
Step-by-step explanation:
answer:
3x - 18 = 2y
5x - 6y = 14
5x - 3*(2y) = 14
5x - 3*(3x - 18) = 14
5x - 9x + 54 = 14
-4x = -40
x = 10
3*10 - 18 = 2y
30 - 18 = 2y
12 = 2y
y = 6
That is the answer. hopefully I can help you.
