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

Mathematics
1 answer:
Viefleur [7K]3 years ago
4 0

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.

Ming has a goal to jog 4 1/2 mile each day. On Monday she jogged 5 9/16 miles. By how much did she exceed her goal for that day?
Darya [45]

5 9/16 - 4 1/2= 1 1/16

I got this because you have make the fractions denomenators equal to subtract them. Once you find how to make them equal you need to mutiply the top numbers the same as the bottom so you can make the new fractions that are equal to the ones before. Then you subtract them and the wholes as well. LOOK BELOW.....

9 x1 9

_ = _

16 x1 16

1 x8 8

_ = _

2 x8 16

9/16-8/16= 1/16 of extra miles

5-4=1 of extra miles

1 and 1/16 of extra miles on monday
