The answer would be c. because 2-1= 1 and 3/5x - 1/5x= 2/5x. All adding up to 1+2/5x.
Answer:
26/5 or 5 1/5
Step-by-step explanation:
First convert 2 3/5 into an improper fraction: 13/5.
Then multiply this result by 2: 2(13/5) = 26/5. This is the answer as an improper fraction.
26/5 as a mixed number would be 5 1/5.
-x + 5y = 8
multiply this equation by 3
-3x + 15y = 24
now add it to the other equation ( elimination)
-3x + 15y = 24
3x + 7y = -2
-----------------------
0x + 22 y = 22
divide each side by 22
y =1
substitute into -x + 5y =8 to find x
-x + 5(1) = 8
-x + 5 = 8
-x =3
divide by -1
x =-3
Answer (-3,1)
Choice A
1/9 - 5/6
Convert both of them into denominators of 18.
2/18 - 15/18
Subtract the numerators and keep the denominator:
