Answer:
no solution
Step-by-step explanation:
Suppose the system equations are:
y = (-1/4)x + 2 (1)
3y = (-3/4)x – 6 (2)
If we multiply equation (1) by 3:
3y = (-3/4)x + 6 (1)
3y = (-3/4)x – 6 (2)
then subtract it from equation (2):
0y = 0x – 12
0 = -12
This is not possible, therefore, the system equation has no solution
13.1 7500 divided by 8:3:1 is 31.1

Step-by-step explanation:
Step-by-step explanation:
b^(-2) / ab^(-3)
= 1/a * [b^(-2)/b^(-3)]
= 1/a * b = b/a.

ANSWER:
10
The length of line BC is 10.
EXPLANATION:
Triangle ABC is four times the area of triangle AYX.
Area of triangle ABC = 4 × Area of triangle AYZ
This is as:
30 = 4 × 7.5
THEREFORE:
The length of line BC must be twice of the length of line XY.
BC = 2 × XY
BC = 2 × 5
BC = 10
