ANSWER:
Sum of the given two numbers,
57 + 34 = 91
Now, the one's digit is less than 5.
So, Estimated number is 90.
F(g(x))=7g(x)+4
f(g(-3)=7 V(-3+4) + 4= 7*1+4=7+4=11
the answer is 11
Y+9x-2=8
That's the answer because y=-5 as yku said so to make an equation yiu could use that and you already solved it so it's Y plus 9 multiplied by -2 is equal to 8 :)
The answer is one eighth because since a whole is 8 and seven eights is eaten, there is one eighth left.
