X/5-4
The quotient of a number x and 5 is x/5.
Four less means you will subtract 4 from it.
Answer: Subtraction property of equality.
Step-by-step explanation:
n + 9 = -3
You are trying to move 9 from one side to the other. To do that, you have to do the <em>inverse operation</em> and <u>subtract</u> nine from both sides. Your result would be n = -12.
Answer:
7 Rows with one row having 6 Chairs. The other 6 Rows will have 8 chairs each.
6x8 = 48 chairs + 1x6 = 54 chairs.
Step-by-step explanation:
1 Row = 8 Chairs [1Row/8Chairs]
(1Row/8Chairs)*(54Chairs) = (54/8) Rows = 6.75 Rows
The manager needs 7 rows, one row will have only 6 chairs [(0.75 Rows)*(8Chairs/1Row) = 6 Chairs
-3(2^2) - 3(-1) + 3(3^2) - 2(-1^3)
-3(4) - 3(-1) + 3(9) - 2(-1)
-12 + 3 + 27 + 2
-9 + 27 + 2
18 + 2
20
