Answer:

a = 25 , b = 14

Step-by-step explanation:

For A

a/5 + 3 = 8

a/5 = 8 - 3

a/5 = 5

Cross multiply

a = 5 * 5

a = 25

For B

3b/7 - 1 = 5

3b/7 = 5 + 1

3b/7 = 6

Cross multiply

3b = 42

b = 42 / 3

b = 14

−2 1/4=r−4/5<br><br> What is r?
dmitriy555 [2]

Answer:

r = -29/20 or r = -1.45

Step-by-step explanation:

I believe you are saying that the equation is -2 1/4 = r - 4/5. If so, then I would solve it in this way:

-2 1/4 = r - 4/5

-9/4 = r - 4/5

-9/4 (20) = r (20) - 4/5 (20)

-45 = 20r - 16

20r = -29

r = -29/20

r = -1.45

Check:

-2 1/4 = r - 4/5

-9/4 = r - 4/5

-2.25 = r - 0.8

-2.25 = -1.45 - 0.8

-2.25 = -2.25

-9/4 = -9/4

in February Frank spent 49 hours watching Netflix in March he only spent 36.26 hours watching what was the percent decrease in t
Lisa [10]

Answer:

26

Step-by-step explanation:

Okay so first, let's write out an equation:

36.26/49 = x/100

Then, multiply both sides by 100 to get the x isolated.

x = 74

100-74 = 26

So the percent decrease is 26
