Step-by-step explanation:
Ellen, Joe, Steve, Patty
Answer:
If, a = 2 and b = 3
It's not equivalent.
It's equivalent.
The correct equation is 4a + 9b.
16:12
(4+12)=16
16/4 = 4
4x3=12
Another method:
4---------3
16-------x
Cross multiplication
4x=16x3
4x=48
x=12
Work done = Force × displacement
= 350 × 40
=14000J
if its 3 - 4/7 then it = 2 3/7
if its 3*-4/7 then it = -12/7 = - 1 5/7
