Set up the equation 64.8 = .36x
Divide by .36 on both sides.
You get 180 = x.
36% of 180 is 64.8
Multiply .36 by 180 to double check.
Hope this helps
Answer:
84cm^2
Step-by-step explanation:
P=2l+2w
We are given,
P=40cm
l=2w+2
Plug these into the first formula and solve for the dimensions,
length and width, of the rectangle:
40=2(2w+2)+2w Simplify
40=4w+4+2w
40=6w+4
36=6w
6=w OR the width is 6cm, therefore,
the length is
l=2(6)+2
l=14cm
To calculate the area of a rectangle, A=lw,
plug the length,14cm, and the width, 6cm, into this formula
A=(14)(6)
A=84cm2 OR the area of the rectangle is 84cm^2
Option B:
Solution:
Take LCM of the denominators and Make the denominators same.
LCM of 16, 320, 1 = 320
All the denominators are same, so you can write in one fraction.
Do cross multiplication.
Add 9280 on both sides of the equation.
Subtract 20x on both sides of the equation.
Let y = f(x).
Hence Option B is the correct answer.
6 1/3 My bad, didn't realise it lol.
