Answer:

(1,4)

Step-by-step explanation:

2x-3y=-10

y=4x

Since the y is already isolated, you can use substitution to find the answer to this equation. Simply replace any y values in the first equation with 4x:

2x-3(4x)=-10

2x-12x=-10

-10x=-10

x=1

y=4(1)=4

Hope this helps!

The answer is 280 because you multiply 7cm x 2cm , then 2cm x 14cm, then you multiply is 14cm x 7cm . Then 7x2=14 , 2x14=18 ,then 14x7=98. So multiply 28,96, and 14 by 2 to get 196 ,56, and 28. Then your total will come up to 280

Answer:

137°

Step-by-step explanation:

Basically, its the reverse of question 1.

With angle x, you can find out that the opposite angle is 360 - 106 = 254°

the angle is twice the size of angle y as said in the corcle theorems.

254 divided by 2 = 137°
