Basically what you have to do is substitute the variables for the values
-4+-9+5= -8
-2-3= -5
2= 2
6-4+1= 3
-9(-2+-4--3)= 27
Answer:
The solution of the equation 9x=7(x+2) is:
Option D) 7
Step-by-step explanation:
9x=7(x+2)
Eliminating the parentheses applying distributive property:
9x=7(x)+7(2)
Multiplying:
9x=7x+14
Grouping the x's on the left side of the equation: Subtracting 7x both sides of the equation:
9x-7x=7x+14-7x
Subtracting:
2x=14
Solving for x: Dividing both sides of the equation by 2:
2x/2=14/2
Dividing:
x=7
Solution: x=7 (option D)
7 goes into 357 51 times. First you take 35 and see how many times 7 goes into that and that is 5 than you take 7 and see how many times 7 goes into that and that is 1 time so that you take your to answers and you get 51 as the final answer.
Answer:
see below
Step-by-step explanation:
The first step is to combine like terms
4x -12 + 2x
6x -12
Then determine the number of terms
2 terms so it is a binomial
By looking at the problem, we can tell that 466 dollars is 2/3 of the original price. therefore, 1/3 of it would be 233 so the original price is 699
