Answer:

x = -5

Step-by-step explanation:

3(1 + x) = 2(x + -1)

(1 * 3 + x * 3) = 2(x + -1)

(3 + 3x) = 2(x + -1)

Reorder the terms:

3 + 3x = 2(-1 + x)

3 + 3x = (-1 * 2 + x * 2)

3 + 3x = (-2 + 2x)

Solving :the equation

3 + 3x = -2 + 2x

add '-2x' to each side of the equation.

3 + 3x + -2x = -2 + 2x + -2x  

Combine like terms: 3x + -2x = x

3 + x = -2 + 2x + -2x

combine like terms: 2x + -2x = 0

3 + x = -2 + 0

3 + x = -2

Add '-3' to each side of the equation.

3 + -3 + x = -2 + -3

Combine like terms: 3 + -3 = 0

0 + x = -2 + -3

x = -2 + -3  

Combine like terms: -2 + -3 = -5

x = -5  

divide each side by '1'.

x = -5

3. The pay rate for employee C is less than the pay rate for employee B
mel-nik [20]

Answer:

y = xc

Step-by-step explanation:

Let the pay rate for employee C per hour is $c and the pay rate for employee B per hour is $b and the pay rate for employee A per hour is $a.

Now, it is given that b > c > a.

Now, the equation for the possible pay y in dollars per day that C earns working x hours per day will be y = xc.

Therefore, the equation for possible pay to employee C is y = xc. (Answer)

Evaluate (-2 4/5)-(-1 5/6)​
iragen [17]

Answer:

(-29)/30

Step-by-step explanation:

Simplify the following:

-(2 + 4/5) + (1 + 5/6)

Put 2 + 4/5 over the common denominator 5. 2 + 4/5 = (5×2)/5 + 4/5:

-(5×2)/5 + 4/5 + 1 + 5/6

5×2 = 10:

-(10/5 + 4/5) + 1 + 5/6

10/5 + 4/5 = (10 + 4)/5:

-(10 + 4)/5 + 1 + 5/6

10 + 4 = 14:

-14/5 + 1 + 5/6

Put (-14)/5 + 1 + 5/6 over the common denominator 30. (-14)/5 + 1 + 5/6 = (6 (-14))/30 + 30/30 + (5×5)/30:

(6 (-14))/30 + 30/30 + (5×5)/30

6 (-14) = -84:

(-84)/30 + 30/30 + (5×5)/30

5×5 = 25:

(-84)/30 + 30/30 + 25/30

-84/30 + 30/30 + 25/30 = (-84 + 30 + 25)/30:

(-84 + 30 + 25)/30
