I think it’s 2x-15, sorry if I’m wrong
So "one fourth of her number" basically means 1/4 of an unknown number, x. So 1/4x. then susan subtracts 11. So its 1/4x - 11 = 11 (because she gets 11)
Answer:
the answer is C
Step-by-step explanation:
i just went over this question like just now
If you want to find by how much percent something increased, take the final value and divide it by the initial value. When you divide 50 by 30, you get 5/3, which can be written as 1.666(repeating). Then, you subtract 1 from the answer and multiply by 100. So, the population of APES students grew by 66.66%
Answer:
x=-17
y=-2 2/3
Step-by-step explanation:
start with the second one and do substitution
x -6y=-1 add the -6y over to get x alone
x=6y-1 put this into first equation
2(6y-1)-15y=6 distribute
12y-2-15y=6 add like terms
-3y-2=6 add the -2 over
-3y=8 divide by -3
y=-2 2/3 put this back into the first equation that was solved for x
x=6(-2 2/3)-1 distribute
x=-17
