Whatever the answer to.
-7y=28

y=-24

Step-by-step explanation:

y = -4

Step-by-step explanation:

to find that you have to isolate the variable, y

and since -7 is being multiplied to the y you have to get rid of it by doing the opposite, dividing

and whatever you do to one side of the equal sign you MUST do it to the other

so

-7y = 28

/-7     /-7

y = -4

and there's your answer

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
