Y = 3x - 7
6x - 2y = 12
6x - 2(3x-7) = 12
6x - 6x -7 = 12
-7 = 12
6x - 2y = 12
6x = 12 + 2y
x = 12/6 + 2y/6
x = 2 + y/3
y = 3x - 7
y = 3(2 + y/3) - 7
y = 6 + 3y/3 - 7
y = 6 + y - 7
y - y = 6-7
0 = -1
B.) THERE IS NO SOLUTION.
Answer:
Step-by-step explanation:
Length of fence = Perimeter of triangle
= 10 + 20 + 15
Length of the fence = 45 m
Cost of fencing per meter = Rs. 25
Cost of fencing 45 m = 25 * 45
= Rs. 1125
<u>Answer:</u>
3 miles 26 yards
<u>Step-by-step explanation:</u>
We are to perform subtraction on the following:
8 mi 133 yd 2 ft – 5 mi 107 yd 2 ft
We have to divide the amount of miles from miles, yards from yards and feet from feet. So a good idea is to write it this way in order to avoid any confusion:
8 mi 133 yd 2 ft
- 5 mi 107 yd 2 ft
_______________
3 mi 26 yd 0 ft
_______________
So we are left with 3 miles 26 yards.
