Which expression is equivalent to (12x−5y−1)+(17y−4−13x−3y)? which one is it?

1. −4x+12y−5
2. −x+9y−5
3. −x−25y+5
4. 25x−19y+3

The expression that is equivalent to the given expression is -x+9y−5. The correct option is 2. −x+9y−5

From the question,

We are to determine the expression which is equivalent to the given expression.

First, we will simplify the given expression

The given expression is (12x−5y−1)+(17y−4−13x−3y)

The expression can be simplified as shown below

(12x−5y−1)+(17y−4−13x−3y)

12x−5y−1+17y−4−13x−3y

Collect like terms

12x−13x+17y−5y−3y−4−1

This becomes

-x+9y−5

The simplified expression is -x+9y−5

Hence, the expression that is equivalent to the given expression is -x+9y−5. The correct option is 2. −x+9y−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
