-18 = -3x

11 answers

To solve for x, we can divide both sides of the equation by -3:

-18 / -3 = -3x / -3

Simplifying gives:

6 = x

Therefore, the solution to the equation -18 = -3x is x = 6.
-35 = u/6
To solve for u, we can multiply both sides of the equation by 6:

-35 * 6 = (u/6) * 6

Simplifying gives:

-210 = u

Therefore, the solution to the equation -35 = u/6 is u = -210.
(x+2)9
To simplify the expression (x + 2) * 9, we can distribute the 9 to both terms inside the parentheses:

9 * x + 9 * 2

Simplifying gives:

9x + 18

Therefore, (x + 2) * 9 simplifies to 9x + 18.
9(6-y)
To simplify the expression 9(6-y), we can distribute the 9 to both terms inside the parentheses:

9 * 6 - 9 * y

Simplifying gives:

54 - 9y

Therefore, 9(6-y) simplifies to 54-9y.
A car corporation produced 1520 fewer cars this month than last. Write a signed number to represent this month's change in production.
To represent this month's change in production, we can write -1520. The negative sign indicates that there were 1520 fewer cars produced compared to the previous month.
9x9x9
To calculate 9x9x9, we can simply multiply these three numbers together:

9 x 9 x 9 = 729

Therefore, 9x9x9 is equal to 729.
