2x+1 since Sara has twice as many (2x), and one more (+1).

If Sara owns one more than twice as many books that Franks has then she has twice as many plus one more. Say Frank has 12 books, multiply that by 2 and then add 1.

Your equation should look like this: S= 1 + 2x

Convert 2 Liters to gallons. Use the fact that 1 gal.= 3.8L.

iris [78.8K]

we know that

1 gal.= 3.8L

we can also write as

3.8L=1 gal

Firstly, we will find for 1L

so, we can divide both sides by 3.8

$\frac{3.8}{3.8} L=\frac{1}{3.8}gal$

$1 L=\frac{1}{3.8}gal$

now, we will multiply both sides by 22

$22*1 L=22*\frac{1}{3.8}gal$

$22L=5.78947 gal$

$22L=5.8 gal$

so, option-b.............Answer
