Solve the equation.

Sphinxa [80]

Answer:

$x=-5$

Step-by-step explanation:

$4-2(x+7)=3(x+5)$

Distribute:

$4-2*(x)-2*(7)=3*(x)3*(5)$

Simplify

$4-2x-14=3x+15$

Simplify each side by combining like terms

$-2x-10=3x+15$

Add 10 to both sides

$-2x-10+10=3x+15+10\\-2x=3x+25$

Subtract 3x from both sides

$-2x-3x=3x-3x+25\\-5x=25$

Divide both sides by -5

$\frac{-5x}{-5} =\frac{25}{-5} \\x=-5$

Done

What is the solution to this system of equations?

Answer:

Step-by-step explanation:

There's no solution because they are not touching each other. If they intersected at one point there would b one solution and if one is exactly on top of another there's infinity solutions which looks like only one line.

A garden is in the shape of a square with a perimeter of

ElenaW [278]

The perimeter of a square is the sum of its sides and they are all equal, so to obtain the length of each of them we divide the perimeter of the first fence between 4:

P1= 64 feet/4 sides

P1= 16 feet

Then, the length of each side of the second fence will increase 2 feet at each end, as shown in the figure. We have then that the perimeter of the second fence is:

P2 = 20 feet x 4 sides

P2 = 80 feet

The sum of the perimeters of both fences is:

PT = P1 + P2

PT = 64 feet + 80 feet

PT = 144 feet

Total cost = 1.17 $ x 144 feet

Total cost = 168.48 $

The total cost of the fences was $ 168.48
