Write and solve a proportion to complete the statement. round your answer to the nearest hundredth. 2.5 l ? gal

Step-by-step explanation:

We need to convert 2.5 L to gal.

We know that

1 L = 0.264172 gal

Now,

       .... (1)

Let . So, we get

         ... (2)

On equating both proportions (1) and (2) we get

On cross multiplication we get

We need to round the answer to the nearest hundredth. It means we need to round the answer to two decimal places.

Therefore, .

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
