So perimeter is equal to 2 lengths and 2 width so the equation would be P=2L+2W. you know width so you plug in 5 for W then solve for L and you should get L=3
Answer:
49x+36
Step-by-step explanation:
Hey There!
for this question they would like you to simplify the expression using distributive property
To do this the first step is to distribute the 9 in to everything that is in the parenthesis
9x5x=45x
9x4=36
so now we have
45x+36+4x
the next step is to combine like terms
the only like terms in the expression are 45x and 4x so we just add the two together
45x+4x=49x
so now we have 49x+36
In conclusions the simplified version of that expression is 49x+36
Answer:
The price of having her car detailed before tax = $55
Step-by-step explanation:
She pays the cashier with a $100 bill and gets $40.60 in change.
She paid = $100 - $40.60
= $59.40
Sales tax = 8%
what was the price of having her car detailed before tax?
Let x= price of having her car detailed before tax
8% of x + x = $59.40
(0.08 * x) + x = $59.40
0.08x + x = 59.40
1.08x = 59.40
Divide both sides by 1.08
x = 59.40 / 1.08
x = $55
Therefore, the price of having her car detailed before tax is $55
Check:
8% of $55
= 0.08*55
= $4.40
Tax + price before tax
$4.40 + $55
= $59.40
