X-6y=-30...equatn 1
-2x-5y=-25....equatn 2
multiply eqn 1 and 2 with 5 and 6 respectively
5x-30y=-150
-12x-30y=-150
subtract to eliminate y
17x=0
x=0
substitute x=0 into any of the equations
0-6y=-30
-6y=-30
y=-30/-6
y=5
x=0;y=5
You will find the ratio of the perimeters by writing the length of 28 yards over 8 yards and simplifying it.
28/8 = 7/2
To find the ratio of the areas, you will multiply this by itself because there are two dimensions in an area.
7/2 x 7/2 = 49/4
The second choice is correct.
Answer: D
Step-by-step explanation:
(5) = 4(6) - 19
5= 24-19
5= 5
TRUE
(5) = -3(6) + 23
5 = -18 + 23
5=5
TRUE
