Answer:

The value of r is 1.

Step-by-step explanation:

-11r + 88 = 77 Subtract 88 from both sides

-11r = -11 Divide -11 on both sides to isolate the variable, r.

r = 1

You must isolate the variable in order to solve equations with variables.

Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on ONLY one side of the equation.

translate this into an expression: the quotient of a number, x, and 8, could you please explain it to me?

Xelga [282]

Answer:

x/8

Step-by-step explanation:

First, we are given "the quotient of...". This means that we are dividing something/something else. If two numbers are given in the phrase "something and something else", the first number given will be the something, and the second number will be the something else.

The first number listed is x. Therefore, we have

x/something else.

Next, we are given "and 8", so we have x/8 as our expression

Which integer is closest to 0 on the number line?

Elenna [48]

The answer is C, 1.
In a number line, the larger number it gets, the more of the right side they're. The smaller the number, the more left side they get.
So, on a number line, 1 is just at the right side of 0, all the other options are at least one more place away from 0.
