Answer:
x must equal 5 and y must equal 2
therefore,
5a + 2b = 23 and
5a - 2b = 7.
I'm gonna take 5a + 2b = 23 and add 7 to each side:
5a + 2b + 7 = 30
and substitute 5a -2b in for 7 on the left side:
5a + 2b + (5a-2b) = 30
10a = 30
a = 3
Now we know a. Now take
5a -2b = 7
and substitute in 3 for a
5*(3) - 2b = 7
15 -2b = 7
8 = 2b
b = 4
a = 3 and b = 4

Answer:
B) F
You put √22 in a calculator and it gives you ≈ 4.69
It would help if you find common denominator... 12
so 1/3 times 4 both the numerator and denominator
4/12
and 3/4 times by 3 both the numerator and denominator
9/12
the recipe calls for 4/12 cup of oil and you have 9/12
two batches would be 8/12 cups of oil, you have 9/12 that is just enough for the recipe for two batches...
now to simplify it again, 1/3 + 1/3 = 2/3 and 2/3 is less than 3/4
the answer would be the upper right
