Sara is a librarian and works at least 10 hours per week. If Sara would like to work extra shifts, they are added to her schedule in two-hour increments. Which equation models the number of hours that Sara will work at the library this
week? Assume x is the number of two-hour increments and y is the total number of hours worked.

y = 10 + 2x

or

y = 2x + 10

Step-by-step explanation:

She works a fixed 10 hours each week, so we start with

y = 10

Now she adds 2-hour increments. She can have 0, 1, 2, or another number of increments. x represents the number of increments. Since each increment is 2 hours, 2x represents the number of hours added by the increments. Now we add 2x to the fixed number of hours.

y = 10 + 2x

or

y = 2x + 10

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

answer is 67%
