this is not the case in -22.96 as the decimal 0.96 constitutes the faction component of the number

Multistep Alex needs to varnish the top and the bottom of a dozen rectangular wooden planks. The planks are 8 feet long and 3 feet wide. Each pint of varnish covers about 125 square feet and costs $3.50. a. What is the total area that Alex needs to varnish? b. How much will it cost Alex to varnish all the wooden planks?

Answers

top and bottom
find area of each plank top and m ultiply by 2 then by number of planks
8*3*2*12 (dozen=12)
576

he needs to varnish 576 ft^2
how many 125's are at least 576 (round up since he can't buy fractios of a pint probably)

125x>576
dividee both sides by 125
x>4.608
x=5

5 times 3.5=17.5

a. 576 ft^2
b. $17.5

Use addition to solve the linear system of equations. Include all of your work in your final answer. x-y=6 y=x-4

Answers

Answer:

no solutions

Step-by-step explanation:

x-y=6

y=x-4

Subtract x from each side

-x+y = x-4-x

-x+y = -4

Add this to the first equation

x-y=6

-x+y = -4

---------------

0x + 0y = 2

0=2

This is never true so there are no solutions

Answer:

No solutions.

Step-by-step explanation:

x - y = 6

y = x - 4

Solve for x in the first equation.

x = 6 + y

Put x as 6 + y in the second equation and solve.

y = (6 + y) - 4

y - y = 6 - 4

0 = -2

There are no solutions.
