Find the value of x that makes lines u and v parallel.

the answer is x=10

Step-by-step explanation:

10*10=100

100-10=90

the red square means 90°

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
