We know that ∠1 equals ∠3, from that we can find x:

$10x = 100 \\ x = 10$

The sum of ∠1 and ∠2 must equal 180°:

$10x + 10y + 20 = 180$

Since we already know x, we can solve for y:

$10 \times 10 + 10y + 20 = 180 \\ 10y + 120 = 180 \\ 10y = 60 \\ y = 6$

Result: x=10, y=6

The number of gallons g of fuel used on a trip

Margaret [11]

17.78 gallons are required for a trip of 400 miles.

<u>Solution:</u>

Given, the number of gallons g of fuel used on a trip varies directly with the number of miles m traveled.

A trip of 270 miles required 12 gallons of fuel,

We have to find how many gallons are required for a trip of 400 miles?

now, according to given information,

270 miles ⇒ 12 gallons

400 miles ⇒ "g" gallons

So, by chris cross method

$\mathrm{g} \times 270=400 \times 12 \rightarrow \mathrm{g}=\frac{400 \times 12}{270} \rightarrow \mathrm{g}=\frac{400 \times 4}{90} \rightarrow \mathrm{g}=\frac{40 \times 4}{9} \rightarrow \mathrm{g}=\frac{160}{9}$

= 17.77 ≈ 17.8

Hence, 17.8 gallons are required for 400 miles.
