Answer: AB = 21
Step-by-step explanation:
Find the value of x by setting them equal to each other
x + 5 = 2x - 11
solve like a normal two step equation
x = 16
It's 340. You multiply 400 by .85 to get your answer.
True. If they never intersect then they must have the same slope and are parallel
Answer:
C. 1 and 3
Step-by-step explanation:
You are right, now here's why.
You are looking for two equations that have the same constant of proportionality. That means they behave the same, that if you enter a X value in one, you'll get the same effect as if you enter it in another.
If you look at all four equations, you'll see that 1 and 3 are essentially the same thing, just that the first one is simplified (4y = 3x) while the other isn't (8y = 6x). But for each time you enter a X value, the Y value will be 33% (1/3) bigger.
The answer would be 2.6.
2 3/5 = 2 + 3/5
multiple = 20
3 * 20 over 5 * 20
60/100
0.6
(2.6)
