3(x-1)-2(2x+1)=8(x-1) Distribute 3 to x and -1, -2 to 2x and 1, and 8 to x and -1.
3x-3-4x-2=8x-8 Simplify
-x-5=8x-8 Add x and 8 on both sides.
3=9x Divide by 9
x= \frac{3}{9} = \frac{1}{3}
\frac{1}{3} is your answer

The simplified polynomial that represents how many more economy cars are rented in w weeks than full-size cars is 53 - w.

<h3>Linear equation:</h3>

Linear equation is an equation in which the highest power of the variable is equals to one.

Therefore, the number of economy-size cars rented in w weeks is represented as follows:

  • 152 + 3w

The number of full-size cars rented in w weeks is represented as follows:

  • 99 + 2w

where

w = number of weeks

A  simplified polynomial that represents how many more economy cars are rented in w weeks than full-size cars is as follows:

  • 152 + 3w - (99 + 2w)
  • 152 + 3w - 99 - 2w
  • 53 - w

What is the simplified expression for 4 power 4 multiplied by 4 power 3 over 4 power 5?
Rus_ich [418]
(4^4 * 4^3) / 4^5 = 

when multiplying exponents with the same base, add the exponents
(4^4 * 4^3 = 4^(4 + 3) = 4^7

now we have 4^7 / 4^5

when dividing exponents with the same base, u subtract the exponents.
4^7 / 4^5 = 4^(7-5) = 4^2 <===

One freezer costs $623.95 and uses 90 kilowatt hours (kwh) of electricity each month. A second freezer costs $500 and uses 100 k
lutik1710 [3]

The minimum electric rate in cents per kwh for which the 12-year total cost will be less for the first freezer is 8.61 cents

<h3>How to calculate the rate?</h3>

Let x =  minimum electric rate (Cents/kWh)

Total months in 12 years is 12*12 = 144 m

1st freezer

Total cost over 12 years is

623.95 (cost) + (90 kWh/m)*(144 m)(x/100 $/kWh)

= 623.95 + 129.6x

2nd freezer

Total cost over 12 years is

500 + 100*144*(x/100)

= 500 + 144x

For the 1st freezer to cost less over 12 years,

623.95 + 129.6x < 500 + 144x

123.95 < 14.4x

8.61 < x

The minimum rate is 8.61 cents per kWh
