Answer:
let W and R represent white toothpaste and red toothpaste represently
n(W)=143
n(R)=135
n(WnR)=70
n( WuR)=?
Now,
n(WuR)=n(W)+n(R)_n(WnR)
=143+135_70
=208
that's all don't forget to write therefore.
Answer:

Explanation:
Volume = 1/3(area of base) times height. 1/3(PI X R(squared)) X height. 1/3 x 3.14 x 25 x 6 = 157

Answer:
y = 18.38 + 0.0634x
Step-by-step explanation:
Given,
Monthly base charge = $18.38,
Also, the cost of each kilowatt-hours = 6.34 cents = $ 0.0634
( 1 cents = 0.01 dollars ),
So, the cost of x kilowatt-hours = 0.0634x,
If y represents the total monthly charge ( in dollars ) for x kilowatt-hours,
Thus, the total monthly charge for x kilowatt-hours = base charge + cost of x kilowatt-hours,
⇒ y = 18.38 + 0.0634x
Which is the required equation.
