Jacqueline has two part-time jobs. She earns $15 per hour, l, working as a lab assistant, and $12 per hour, s, working as a cashier. This is modeled by 15l + 12s. Evaluate for l=5 and s=7 to find how much money Jacqueline will earn at her two jobs this week. (1 point)

To find how much money Jacqueline will earn at her two jobs this week, we substitute l=5 and s=7 into the expression 15l + 12s.
15(5) + 12(7)
= 75 + 84
= 159
Therefore, Jacqueline will earn $159 at her two jobs this week.
15(5) + 12(7)
= 75 + 84
= 159
Therefore, Jacqueline will earn $159 at her two jobs this week.

To simplify the expression 5a - 8c + b + 3c - 9a + 6b, we can combine like terms.
Combining the terms with the same variables:
(5a - 9a) + (-8c + 3c) + (b + 6b)
Simplifying:
-4a - 5c + 7b
Therefore, the simplified form of the expression 5a - 8c + b + 3c - 9a + 6b is -4a - 5c + 7b.

To simplify the expression -3/4 + 3 - 5/6r - 6, we can combine like terms.
First, let's rewrite -3/4 as an equivalent fraction with a common denominator of 12:
-3/4 = -9/12
Now rewrite -5/6r as an equivalent fraction with a common denominator of 12:
-5/6r = -10/12r
Combining the terms:
-9/12 + 3 - 10/12r - 6
Now, let's simplify further by combining the like terms:
-9/12 - 10/12r + 3 - 6
-19/12 - 10/12r - 3
Now, let's combine the numerical terms and keep the variable term separate:
-22/12 - 10/12r
We can simplify this fraction by dividing the numerator and the denominator by the greatest common divisor, which in this case is 2:
-11/6 - 5/6r
Therefore, the simplified form of the expression -3/4 + 3 - 5/6r - 6 is -11/6 - 5/6r.
