X - 6 is th algebraic expession for six lss than a number. x represents the number and you are taking 6 away from it. This is the basis of all algebra
For this case we have the following expression:
((x-4) / (6)) / ((x + 1) / (7))
Rewriting we have:
7 (x-4) / 6 (x + 1)
We observe that the expression is not defined for the values where the denominator is equal to zero.
We have then:
x + 1 = 0
x = -1
Answer:
The excluded value of the rational expression is:
A. -1
9x + 3 = 7x +19
2x + 3 = 19
2x = 16
x = 8
So, x (8) is the number of chairs in each row with these setups.
Plug 8 into one of the equations and you will find how many chairs total there are.
9(8) + 3 = 75
There are 75 chairs total
Answer:
255
Step-by-step explanation:
1200-945 is 255
Answer:
I believe the correct answer would be A: 3/5 = 60
Step-by-step explanation:
Firstly, the second option is wrong because 0.06 would be 6 hundredths, so that is wrong, the third option would be incorrect because 0.002 would equal 2 thousandths so that is also wrong, and the fourth option would be 25% instead of 75%, so your answer should be A.
