Ernie worked at his job on Saturday and Sunday last weekend, earning $14 per hour. His sister, Perla, also worked on the weekend and earned a total of $126.
If Ernie and Perla earned the same amount of money at their jobs last weekend, how many
hours did Ernie work?

9 hours

Step-by-step explanation:

126 divided by 14 = 9

You can check your answer by 9 times 14 which would give you 126.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

answer: answer is b.

[m < b = 120º]
