-x/6 + 6 = 32<br> What is the answer and how do I solve it
masha68 [24]

Answer:

x= -120

Step-by-step explanation:

-x/6+6+6=32

  1. Use -a/b=a/-b= -a/-b to rewrite the fraction.
  2. -x/-6+6+6=32
  3. Add the two 6's then you get 12
  4. -x/-6+12=32
  5. Multiply both sides with the equation by 6
  6. -x+72=192
  7. Move the constant to the right-hand side and change its side
  8. -x=192+72
  9. Subtract the numbers, -x=192-72
  10. -x=120
  11. Change the signs on both sides of the equation
  12. You have your answer it is x= -120

Assoli18 [71]

the percent increase in the price of a gallon of milk from 1985 to 2005 is 59%

Define percent increase

Percent increase can be described as the rise in the value of an item, in this case the value is milk.

Write out the parameters

In 1985 the price of a gallon of milk is $2.20

In 2005 the price is $3.50

Formula for percent increase

new price-old price/new price × 100

Calculate the percent increase

new price= $3.50

old price= $2.20

= 3.50-2.20/2.20

= 1.3/2.20

= 0.59 × 100

= 59%

Hence the percent increase from 1985 t0 2005 is 59%
