Answer:
Step-by-step explanation:
-9x + 1 = -x + 17
-8x + 1 = -17
-8x = -16
x = 2
Answer:
899 + 66 = 3*X, X being the wholesale price.
965 = 3*x -> x = 965/3 -> x = 321.66 (and 2/3 of a cent)
Step-by-step explanation:
You could say that you spent (purchased) 85% of the money that you had.
You spent a total of $85.
If you create the fraction 85/100, that is the same as saying you spent 85% of the money.
2(
x + 4) = 
x + 4 which is the second option is the equivalent expression.
Explanation:
First, we need to calculate the value of two-fifths of x. It means 2 portions out of the five portions of x which equates to x.
Now we calculate the values of the two expresssions on the LHS.
1) 2 (two-fifths x + 2) = 2 (x + 2) = x + 4.
2) (two-fifths x + 4) = 2(x + 4) = x + 8.
Now we determine values of the four expressions on the RHS.
1) Two and two-fifths x + 1 = 2x + 1
2) Four-fifths x + 4 = x + 4
3) Four-fifths x + 2 = x + 2
4) Two and two-fifths x + 8 = 2x + 8.
Out of the various LHS and RHS values, the 
LHS value and 
RHS value is the same. So option 2 is the answer.
Answer:
x = 47
Step-by-step explanation:
Every triangle's interior angles add up to 180°.
Let's make an equation.
x + 102 + 31 = 180
x + 133 = 180
x = 47
