Step-by-step explanation:
Answer: Length = 36m
Step-by-step explanation:
P = w * 2 + l * 2
Width = w
Length = w + 5
P = w + w + (w + 5) + (w + 5)
P = 4w + 10
134 = 4w + 10
-10
124 = 4w
/4
31 = w
So, the width is 31m.
Length = 31 + 5
31 + 5 = 36
Therefore, the length is 36m
You can also check this: P = w * 2 + l * 2
31 * 2 = 62
36 * 2 = 72
72 + 62 = 134

Step-by-step explanation:
(10/y + 13) -3
Let y=5
(10/5 + 13) -3
PEMDAS says parentheses first
(2 +13) -3
15 -3

Answer:
$25.
Step-by-step explanation:
Let x be the original price of shorts.
We have been given that a store is having a sale in which all items are reduced 20%. The sales tax is 5%.
The price of shorts after 20% off will be:
Since tax is added after the discount, so the price of shorts after including the tax will be:
We are told that including tax, Jennifer paid $21 for a pair of shorts. So we can set an equation as:
Now let us solve for x.
Therefore, the original price of shorts was $25.
