Mhanifa, can you answer this question pls? Solve for x.
1. 5(2x +15) = 55
2. 9(6x +4) = 166
3. 3(8x +20) = 356

1. x=-2

2. x=65/27

3. x=37/3

Explanation:

Isolate x

1. Divide by 5: 2x+15=11

2x=11-15

x=-2

2. Distribute: 54x+36=166

54x=166-36

x=130/54

Simplify by dividing by 2: x=65/27

3. Distribute: 24x+60=356

24x=356-60

x=296/24

Simplify by dividing by 8: x=37/3

d.) circle motion requires a force to give it a centripetal acceleration.

i just learnt this recently but i need to look through my notes again
