10x-2-6x=2(2x-1)

10-6x (combine like terms)

2•2x, 2•1 (distribute)

4x-2=4x-2

-4x = -4x

-2 = -2

Answer:

<h2>It's the Identity Equation (x ∈ R). All real numbers.</h2>

Step-by-step explanation:

10x - 2 - 6x = 2(2x - 1)            <em>use the distributive property </em><em>a(b + c) = ab + ac</em>

(10x - 6x) - 2 = (2)(2x) + (2)(-1)

4x - 2 = 4x - 2                 <em>subtract 4x from both sides</em>

-2 = -2             TRUE

<em>Conclusion: It's the Identity Equation (x ∈ R). </em>

OleMash [197]
To find the fee for three weeks, we need to multiply the fee for one week by 3.
7.50 * 3 = 22.5
Subtract:
305 - 22.5 = 282.5
Javier will have $282.50

Please help Which of the following inequalities is graphed on the coordinate plane?
Gekata [30.6K]

Answer:

The inequality which represents the graph is y ≤ -2x + 1 ⇒ A

Step-by-step explanation:

To solve the question you must know some facts about inequalities

  • If the sign of inequality is ≥ or ≤, then it represents graphically by a solid line
  • If the sign of inequality is > or <, then it represents graphically by a dashed line
  • If the sign of inequality is > or ≥, then the area of the solutions should be over the line
  • If the sign of inequality is < or ≤, then the area of the solutions should be below the line

Let us study the graph and find the correct answer

∵ The line represented the inequality is solid

∴ The sign of inequality is ≥ or ≤

→ That means the answer is A or B

∵ The shaded area is the area of the solutions of the inequality

∵ The shaded area is below the line

∴ The sign of inequality must be ≤

→ That means the correct answer is A

∴ The inequality which represents the graph is y ≤ -2x + 1

six men completed a task in 24 hours and 48 minutes. how long would it take four men to complete the same task
Komok [63]

Answer:

37 hours and 12 minutes

Step-by-step explanation:

six men completed a task in 24 hours and 48 minutes which means (24 x 60) + 48 = 1488 minutes

x is the number of minutes it would take 4 men to complete

6(1488) = 4x

8928 = 4x

x = 2232

x = 2220 + 12 or 37 hours and 12 minutes

Erwin earns $ 2 , 100 per month. Her deductions amount to 26 % of her paycheck. How much does Erwin take home each month?
Sergeu [11.5K]

Answer:

Credit ⇒ 45

Debit ⇒ $30

Step-by-step explanation:

Credit = $45

Debit = $30

When an account balance increases it means that it has been credited and when it decreases, it has been debited.

The beginning balance here is $0 and the closing balance is $15.

There were 2 transactions, one credit and one debit.

For the closing balance to be $15, the Credit amount must have been $15 more than the Debit amount.
