Answer:
x= 9
y=-12.5
Step-by-step explanation:
3x+2y = 2×2
2x+2y =-7×3
6x+4y =4
- 6×+6y =-21
-2y =25
y=-12,5
2x+2(-12,5)= -7
2x+-25= -7
2x= -7+25
2x/2=18/2
x= 9

Answer:
Step-by-step explanation:
Answer:
=11/4 cm
Step-by-step explanation:
We are finding the perimeter
P = 2(l+w)
l = 3/4 cm
w = 5/8 cm
The common denominator is 8
l = 3/4 *2/2 = 6/8
P = 2(6/8+5/8)
=2(11/8)
=22/8
=11/4 cm (2 1/4 cm)
It says an integer or a fraction, not a mixed number
