Let x be the no. of seconds it takes for the balloons to be at the same height.
7+3x = 12+2x
Deduct both sides by 2x.
7+x = 12
Deduct both sides by 7.
x = 5
Ans: It will take 5 seconds for the balloons to be at the same height.
I think it's C, I could be wrong though
Answer: 2
Steps:
f(-2) = 1/2x^2
f(-2) = 1/2(-2)^2
f(-2) = 1/2(4)
f(-2) = 2
well, what is 9,744/2,280? take that and move the decimal point two places to the right to find the answer.
Do you mean how you can get 16 in a multiplication problem? Then the answer would be 2 times 8 which would equal 16. Hope this helped.
