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.
Answer:
70 meters
Step-by-step explanation:
Find length of right triangle: 16^2+x^2=65^2
256+x^2=4225
x^2=3969
x=63
63+7=70
Answer:
last one
Step-by-step explanation:
u can do it
B. $256.50
1) $400 x .25 = $100 --> $400 - $100= $300
2) $300 x .10 = $30 --> $300 - $30 = $270
3) $270 x .05 = $13.5 --> $270 - $13.5 = $256.50
