you are given 15l + 12s and the values of l and s
= 15(5) + 12(7)
= 75 + 84
= ....
2. 5a − 8c + b + 3c −9a + 6b
= -4a + 7b - 5c
3. same thing
4. ..... easy
5. -4(6a - 5)
= -24a + 20
6. same thing
These questions are quite trivial. If you are having difficulties
with these, then it looks like you have a lot of studying and practising
ahead of you.

Questions 1 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.
Question 2 Simplify 5a − 8c + b + 3c −9a + 6b.
Questions 3 Simplify −3/4r + 3 − 5/6r − 6
Questions 4
Expand 8(3p + 2).
Questions 5
Expand −4(6a − 5).
Questions 6

Bot is @quinn right
Expand -5/6 (9b-12)
WHO IS RIGHT THEN I AM TRYING TO GET ANSWERS BUT YALL ARE CONFUSING ME!
explain bot who is right?
its ok tho i will take the test and come back
explain bot is right except for 3 & 6
3 is -19/12r - 3
6 is 14h+ 21/4
the rest are correct
7 is -15/2 b+10
8 is 4
9 is 6
10 is 4(2a - 7)
11 is 6 (2y+1)
12 is 0.5k-4.2
13 is -1/4z-1
14 is -9c
15 is 4 + 8(3x - 2) - 7x, distribute 8, rearrange terms using commutative property, and then combine like terms to get the simplified expression -12 + 17x6
3 is -19/12r - 3
6 is 14h+ 21/4
the rest are correct
7 is -15/2 b+10
8 is 4
9 is 6
10 is 4(2a - 7)
11 is 6 (2y+1)
12 is 0.5k-4.2
13 is -1/4z-1
14 is -9c
15 is 4 + 8(3x - 2) - 7x, distribute 8, rearrange terms using commutative property, and then combine like terms to get the simplified expression -12 + 17x6
