I believe ur answer is estimate
1. First you multiply by 10 to get rid of the decimals
3x - 5y = 12 and 7x - 2y = -1
2. Since we need to solve by elimation, we want to elimanate a variable. To do that multiple the first equation by 2 and the second equation by -5
6x - 10y = 24
-35x +10y = 5
3. Add the equations downwards
-29x = 29
4. Divide both side by -29
x= -1
5. Solve for y by putting -1 in for x into any of the equations. I'll use 3x- 5y=12
3(-1) -5y = 12
-3-5y=12
-5y =15
y= -3
If your question is "How many gallons of paint will he have left after painting the mural gallon", the answer is:
(11/4+11/3+7/8) * (1 - 3/4) = 175/96 gal ≈1,82 gal

Answer:
938 feet
Step-by-step explanation:
The diagonal is the hypotenuse of a right triangle with side lengths 900 ft and 264 ft. The Pythagorean theorem tells you how to compute its length.
d² = 900² +264² = 879,696
d = √879,696 ≈ 937.92 . . . . feet
They would walk about 938 feet.
