Does anyone know what the system of equations for this would be?
1 answer:
A + b = 10 pounds
rewrie as:
a = 10 pounds - b
0.75a + 0.50 b = $6.00
replace a with the above equation:
0.75(10-b) +0.50b = 6.00
distribute the(10-b):
7.50 - 0.75b + 0.50b = 6.00
combine like terms:
7.50-0.25b = 6.00
subtract 7.50 from each side:
-0.25b = -1.50
divide both sides by 0.25 to find b
b = -1.50 / -0.25
b = 6

If it's not clear what I did above, consider the substitution

It’s A because I took this test
(-72×-11) / (-7x-48) =
792 / 336 = 2.36
or the fraction in simplest terms is 33 / 14
You just need to trace it without moving your pencil off the paper
The perimeter of a rectangle is twice the sum of its side lengths.
P=2(L+W), we are told that L=3W and P=176 so
2(3W+W)=176
2(4W)=176
8W=176
W=22 ft, since L=3W
L=66 ft
So the yard is 22 feet wide and 66 feet long.
