Answer:
3
Step-by-step explanation:
Let's say x was the original price:
3x will be 300% of x.
B-2.5mph You divide 10 (how far you went) by 4 (the amount of time it took you) which gives you 2.5 (the amount of time it takes you to walk 1 mile) To check: It takes you 2.5 hours to walk 1 mile so multipling 2.5 by 4 tells you how far you walked in 4 hours
The answer is 9:16 just add 9+7=16 and then we know out of the 16 nine were dogs so 9:16
Answer:
D
Step-by-step explanation:
Given
(x + y + 2)(y + 1)
Each term in the second factor is multiplied by each term in the first factor, that is
x(y + 1) + y(y + 1) + 2(y + 1) ← distribute parenthesis
= xy + x + y² + y + 2y + 2 ← collect like terms
= y² + xy + x + 3y + 2 → D
