You’re adding -4 to 68, so the answer would be positive. -4 + 68 = 64.

Positive. When given a scenario like this, try moving the negative number to the other side of the equation. This turns it into a regular subtraction problem.

Erika worked 14 hours last week and 20 hours this week. If she earns $9 per hour, how much did she earn during these two weeks?
ozzi

we know that

Erika earns \$9 per hour

so

By proportion

Find how much she earn during the total hours of two weeks

The total hours of two weeks is equal to

14+20=34\ hours

\frac{9}{1} \frac{\$}{hour} =\frac{x}{34} \frac{\$}{hours} \\ \\x=34*9 \\ \\x=\$306

therefore

<u>the answer is</u>

\$306

Finding angles June 23.2020
finlep [7]

Answer:

angle B is 38 degree

Step-by-step explanation:

In triangle ADC,

finding angle C

angle A + angle C = 110 degree (sum of two interior opposite angles are equal to the exterior angle formed)

46 + angle C = 110

angle C = 110 - 46

angle C = 64 degree

In triangle ABC

finding angle B

angle A + angle B + angle C = 180 degree (sum of interior angles of a triangle)

78 + angle B + 64 = 180

142 + angle B = 180

angle B = 180 - 142

angle B = 38 degree
