Answer:
Step-by-step explanation:
momentum=mv=7.50v=70.4
v=70.4/7.5≈9.39 m/s
multiplication is the answer because if a is 4 and you have 4a then you will mulityply and the answer is 16 I you wanted to know
H= -1/43
4h+12=11-39h
4h+39= -12+11 or 11-12
43h= -1
h= -1/43
The second step would be to find the reciprocal of 5/3. When you divide 4/7 by 5/3, you end up with a double-decker fraction (as my teacher called it) which makes things much more difficult. However, to make things easier, find the reciprocal of 5/3 (which is 3/5) so that you can straight up multiply it across. With this done, you can solve for g:
g=4/7*3/5
g=12/35
