tatiyna

Answer:

x = -3/10

Step-by-step explanation:

Solve for x by substituting y = 3x into the other equation:

2x - 4y = 3

2x - 4(3x) = 3

Simplify and solve for x:

2x - 12x = 3

-10x = 3

x = -3/10

So, x = -3/10

What is the measure of _RVE?

marysya [2.9K]

Answer:

D. 45

Step-by-step explanation:

All angles have to = 180°

60 + 75 + <RVE = 180°

135 + RVE = 180°

180 - 135 = 45° RVE

RVE = 45°

Another way to check your answer:

Add all of the angles, and it should equal 180°

60 + 75 + 45 = 180°

Correct!

Jonas runs a pet store that sells guinea pigs. He wants to ensure he has more than 1 pound of dry food for every foge guinea pig

Amiraneli [1.4K]

You can do this by converting this into a ratio or a fraction

Ratio:
1 lb for 4 guinea pigs
1:4
If he was 8 lbs for x guinea pigsit would be

1:4
8:x

Multiply the first ration until the one is equal to 8, then whatever the four turns into is x

Fraction: (easier way)

1/4 (1lb for 4 guinea pigs)
8/x (8lb for x guinea pigs)
1/4 = 8/x
Multiply one until it is equal to 8
Correspond that to the 4

1*8 = 8
4*8 = 32

32 guinea pigs
