2(-2y-4)-3y=13
-4y-8-3y=13
-7y=21
y=-3
x=2
substitute three into one of the original two problems and you get 2!
Hope this helped

Answer:
AC=6
Step-by-step explanation:
You can see that ABC is 4 times bigger that HIJ because of lines AB and HI. HI(with a value of one) had to be multiplied by four to equal AB (a value of 4). Use this same rule to find the side AC.
1.5(the length of HJ) times 4 =6.

Answer:
C. Ф = 4 radians
Step-by-step explanation:
Given,
Radius of the Circle (r) = 3cm
Length of the Arc (S) = 12cm
In any circle of radius r, the arc length S to the circumference equals the ratio of the angle θ subtended by the arc at the centre and the angle in one revolution. Thus, measuring the angles in radians, S=rθ.
Therefore, S = r*Ф
12 = 3*Ф
Hence, Ф = 4 radians
