Answer:
C. 244
Step-by-step explanation:
It costs 79 dollars a month = 79x
It costs 0.15 dollars for every text message over 1000 = 0.15y
The equation is:
79x + 0.15y = z
X = months
Y = Each text message over 1000
Z = the total amount spent
Let's plug in our values
79(1) + 0.15(1100) = z
79 * 1 = 79
0.15 * 1100 = 165
79 + 165 = z
79 + 165 = 244
z = 244

20 * 4 = 80 = perimeter of the square 24*2 = 48, the length of two sides of the rectangle. Deducting from 80 we are left with 32 and dividing by 2 we know the rectangle is 24 x 16 Area = L * W, so you can calculate the area of the rectangle.

Answer:
x = -10
Step-by-step explanation:
Step 1: Write equation
180 + 8x = 160 + 6x
Step 2: Solve for <em>x</em>
- Subtract 6x on both sides: 180 + 2x = 160
- Subtract 180 on both sides: 2x = -20
- Divide both sides by 2: x = -10
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
180 + 8(-10) = 160 + 6(-10)
180 - 80 = 160 - 60
100 = 100
