Answer:
false
Step-by-step explanation:
you can use whatever letters you want to represent things. x and y make sense that you would use just them for graphing, but if it is a word problem you could have like c for cost or t for time or something
Answer:
3x - 8 = 2x + 12
(vertical angles)
x = 20
A straight line = 180 degrees,
so 3(20)-8=52
52+128 = 180
so y is 128.
D + 5 >= 17
We can subtract 5 from each side:
d >= 12
To get 20 on the right, we have to add 8 to each side (20-12=8).
d + 8 >= 20
To get d - 5 from the first expression (d + 5 >= 17) we have to subtract ten from each side (5-10=-5) and we get:
d - 5 >= 7
