X+4y=30 system by substitution <br><br> X-2y=0
Dmitry [639]

Answer:

x=10, y=5

Step-by-step explanation:

For substitution, you always want to get the variable alone. The second equation (x-2y=0) will be easier to substitute into the first equation.

x-2y=0

x=2y

You can substitute 2y as x on the first equation (x+4y=30).

2y+4y=30

6y=30

y=5

Plug y=5 into any equation.

x+4(5)=30

x+20=30

x=10

GEOMETRY
ira [324]

Answer:

Its like how much you multiply the original shape by, to the new one.

For example, if your new shape is double the size of the original shape, then the scale factor is 2, because you would multiply the original by 2, to get the size of the new.

However, if your new shape is half the size, then the scale factor is 1/2, as you multiply the original by half to get the new shape.

Hope this cleared things up, lmk down below if you any further questions.
