Answer:

x = 50, y = 140

Step-by-step explanation:

The angles x, 40 and 90 lie on a straight line and sum to 180° , that is

x + 40 + 90 = 180

x + 130 = 180 ( subtract 130 from both sides )

x = 50

The angle vertically opposite x is congruent to x , that is 50°

y = 90 + 50 = 140

Julio has 5 more dollars than Dan. Altogether, Julio and Dan have $19. Write and solve an equation to represent the situation. H
cluponka [151]

Answer:

Dan has $7 and Julio has $12

Step-by-step explanation:

Julio = x

Dan = y

They both have a total of $19:

x + y = 19

Julio has 5 more dollars than Dan:

(Therefore Dan would need 5 more dollars to catch up to what Julio has)

y + 5 = x

We now plug in one equation into the other and get:

y + (y+5) = 19

2y+5 = 19

2y = 14

y = 7

Plug in Dan's amount into the initial equation and we get:

7+5 = x

x =12
