Answer:
15
Step-by-step explanation:
You have to find the total number of crayons whcih will be 21.
Then you do 21-6 ( red pencil) to get 15
15 pencil not read.
Answer:
7w - 3(4w + 8) = 11
Distribute.
-5w-24=11 Combine like terms on the left side.
-5w=11%2B24 Add 24 to both sides.
-5w=35 Combine like terms on the right side.
w=%2835%29%2F%28-5%29 Divide both sides by -5 to isolate w.
w=-7 Reduce.
Positive × Positive = Positive
3 × 2 = 6
m × n = mn
Positive × Negative = Negative
8 × -4 = -32
m × -n = -mn
Negative × Negative = Positive
-5 × -4 = 20
-m × -n = mn
(-x) × (-x) = x²
The same rules apply for division as multiplication.
