Mathematics
1 answer:
Alchen [17]3 years ago
5 0

Answer:

x = 10, y = 5

Step-by-step explanation:

Substitute the second equation into the x value of the first equation.

-4x + 11y = 15

-4(2y) + 11y = 15

-8y + 11y = 15

3y = 15

y = 5

Now substitute the y value into an original equation.

x = 2y

x = 2(5)

x = 10

Are the ratios 3:5 and 2:4 equivalent?<br> yes or no
jeyben [28]

Answer:

No, they are not.

Step-by-step explanation:

A ratio can be written as a fraction. So 3:5 is the same as 3/5 and 2:4 is the same as 2/4.

3/5 = 2/4

0.6 = 0.5 INCORRECT

As you can see, the both don't equal the same numbers, so they aren't equivalent.
