Can someone please help me? And it says “Solve each equation. Then, prove that your answer solves the original equation?

Mathematics

Viefleur [7K]3 years ago

Step-by-step explanation:

We need to solve each equation.

a. 6c = 30

c = 30/6 = 5

b.

2d-6=12

Adding 6 both sides

2d-6+6=12+6

2d = 18

d = 9

c.

\dfrac{x}{3}+9=2\\\\\dfrac{x}{3}=-7\\\\x=-21

d.

50=14+3m

50-14=3m

36=3m

m = 12

Hence, this is the required solution.

PLEASE HELP
stiv31 [10]

Answer:

I think it would be 34 because I divided 68.2 by 4 and got 17.05, so I multiplied that by 2, and it's closest to 34.

<em>So I think it's A.</em>

But y'all don't be mad if I'm wrong cuz I said I think.

Plz help this is due in 1 hour. 56a = 7/4. What is a?
elena-s [515]
To get a you have to have a on its own side
56a=7/4
divide 56 on both sides
a=56/1 divided by 4/7 (switch 7/4 to 4/7 because you are going from division to multiplication)
a=32
Hope this helped
