Okay, so powers are multiplied out of parenthesis.
Every number of a variable has 1 power.
x^2 + 2^2
x^2+4
I hope this helped!

Perimeter of any figure is all its sides summed up
for a rectangle, with two equal pairs, that means, length + length + width + width or 2length + 2width, or 2(length + width)
but we know the length is 7/5 the width
width = w
perimeter = P

and the length is 7/5 of that
First we have to find 18% of $55.82, which we can do by using the equation 55.82 x 0.18
55.82 x 0.18 = 10.05
so the tip = $10.05
now we just add it to the original bill
55.82 + 10.05 = 65.87
so the total cost = $65.87
Answer:
x = 49
Step-by-step explanation:
Given
=
( cross- multiply )
5(x - 16) = 3(x + 6) ← distribute parenthesis on both sides
5x - 80 = 3x + 18 ( subtract 3x from both sides )
2x - 80 = 18 ( add 80 to both sides )
2x = 98 ( divide both sides by 2 )
x = 49
The original price of the surfboard is 150 dollars. Now, it is on sale which is 30% off the original price.The question is: How much is the newly discounted price of the surf board=> Here are the solutions and the answer=> 30 % = 30% / 100% = .30Now, let's multiply this to the original proce=> 150 * .30 = 45 dollarsNext thing to do is to subtract this to the original price since it;s a discount=> 150 - 45 dollars = 105 dollars is the newly discounted price of the surfboard
