meriva
If you put them into fractions you get 4/3 and 3/2

Now let's give them the same denominator.

3*2=6 and vice versa

So let's multiply the numerators by the same numbers

4/3= 8/6

And 3/2 = 9/6

The second fraction has more parts cranberry so....
She you should ask for 3 cranberry cubes and 2 Apple cubes!

-5x - 2y = 13<br> -4x + y = 0<br> Solve by substation
kotegsom [21]

Answer:

(x,y)=(-1,-4)

Step-by-step explanation:

-4x + y = 0

+4x         +4x

y=4x

-5x - 2y = 13

+5x          +5x

-2y = 5x+13

-2(4x) = 5x+13

-8x=5x+13

-5x -5x

-13x/-13=13/-13

x=-1

Thus:

y=4x

y=4(-1)

y=-4

Solve the following equation by using the addition principle. Check the solution.
omeli [17]

Answer:

y = 11/20

Step-by-step explanation:

-4/5 + y = -1/4

Add 4/5 to each side

-4/5  +4/5 + y = -1/4+4/5

y = -1/4 + 4/5

Get a common denominator

y = -1/4 *5/5   + 4/5 *4/4

y = -5/20 + 16/20

y = 11/20

Check

-4/5 +11/20 = -1/4

Get a common denominator

-4/5*4/4 + 11/20 = -1/4*5/5

-16/20 +11/20 = -5/20

-5/20 = - 5/20

Check
