(8+ 14x) +( 6x+12) = 180 same-side exterior angles are supplementary
combine like terms
20 + 20x = 180
subtract 20 from each side
20 -20+ 20x = 180-20
20x = 160
divide by 20
20x/20 = 160/20
x = 8
Answer: x=8
-5+8y=8
8y= 8+5
8y=13
y= 13/8
So the line would be straight, horizontal, and it will pass through the y axis at y=13/8.
It would have an infinite amount of solutions.
Change each equation into y=mx+b form and then do system of equations.
Answer:
-27
Step-by-step explanation:
I believe it's -27, because 12+15 =27. I made it negative because the temperature is decreasing, not increasing.
Distribute (16x + 20n + 16 * 18)
Simplify 16 * 20n to 320n (320n + 16 * 18)
Simplify 16 * 18 to 288
Therefore in conclusion the answer would be 320n + 288.
