Answer:
166 marbles
Step-by-step explanation:
83 multiplied by 2 is 166
30 = 60% of x
x being our variable, we need to figure out what x equals. Use the formula I put in the attachment. Multiply 30 by 60, and then divide the product by 100. That will give you the answer :)
Answer:
x=9
Step-by-step explanation:
2(x + 6) = 3(x + 1)
2x+12=3x+3
2x+12-12=3x+3-12
2x=3x-9
2x-3x=-9
-1x=-9
-1x÷-1=-9÷-1
x=9
Answer:
4x^2 -8
Step-by-step explanation:
f(x)=3x^2-9
g(x)=x^2+1
(f+g)(x)=3x^2-9 +x^2+1
Combine like terms
= 4x^2 -8
F(n-1) = f(n) - 5, based off of the first one
