Which of these expressions is equal to 0?
a. -24/6 - 4

b. -24/-6 + 4

c. 24/6 + 4

d. -24/-6 - 4

B is the answer

Step-by-step explanation:

Why? It is equal to 0

d. -24/-6 - 4

Step-by-step explanation:

Use order of operation (PEMDAS) to solve.

There are no parentheses.

There are no exponents.

There is multiplication and/or division. Do this first, from left to right.

There is addition and/or subtraction. Do this second, from left to right.

Solve. Remember that a negative times (or divided by) a negative makes a positive.

-24 / -6 = 4

4 - 4 = 0

Check your work. None of the other expressions are equal to 0.

a. -24 / 6 - 4 = -4 - 4 = -8

b. -24 / -6 + 4 = 4 + 4 = 8

c. 24/6 + 4 = 4 + 4 = 8

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
