The answer is 1/9:
.9*10=9
9^-1=1/9
So the answer might be 61.0 because if you subtract (-)63.5 with 2.5 it would 61.0 so i dont know ..but good luck and if i fail you im so sorry
Answer:
x=5
y=7
Step-by-step explanation:
y = x+2 so plug that in the next equation as y
so it be --> 5x+(-4)(x+2)= -3 now use distributive property
(-4 times x)+(-4 times 2)= -4x+-8 replug that back in
5x-4x+-8 = -3 subtract your x
1x = x so ---> x+-8 = -3 now to get rid of -8 we have to add 8 to it
x= -3 but whatever you do to one side u do to the other so u have to add 8 to -3---> so it be x=5
now take that x=5 and plug it in to your first eqaiuton to get y
y=5+2 ---> y =7
The student got 32 questions correct.
