What is the value of 2x in this equation 5x - 2(2x - 1) = 2(3x - 4)

KiRa [710]

Answer:

Step-by-step explanation:

Step 1: Write equation

5x - 2(2x - 1) = 2(3x - 4)

Step 2: Solve for x

Distribute: 5x - 4x + 2 = 6x - 8
Combine like terms: x + 2 = 6x - 8
Subtract x on both sides: 2 = 5x - 8
Add 8 to both sides: 10 = 5x
Divide both sides by 5: 2 = x
Rewrite x = 2

Step 3: Check

Plug in x to verify it's a solution.

5(2) - 2(2(2) - 1) = 2(3(2) - 4)

10 - 2(4 - 1) = 2(6 - 4)

10 - 2(3) = 2(2)

10 - 6 = 4

4 = 4

Here we see that x = 2 is indeed a solution

Step 4: Find 2x

2(2) = 4

Solve the 2x^2 - 5 = 13

DochEvi [55]

Answer:

x=3

x=−3

Step-by-step explanation:

2x^2 - 5 = 13

Subtract 13 from both sides.

2x^2 - 5 - 13 = 0

Subtract 13 from −5 to get −18.

2x^2 - 18 = 0

Divide both sides by 2.

x^2 - 9 = 0

Consider x^2−9. Rewrite x^2−9 as x^2−3^2. The difference of squares can be factored using the rule: a^2−b^2=(a−b)(a+b).

(x−3)(x+3)=0

To find equation solutions, solve x−3=0 and x+3=0.

Job A -Sales- offers a base salary of $1,000 per week plus 3% commission on all sales above $3000. Job B -Sales- offers a base s

Ivahew [28]

Answer:

Job A pay $25 than Job B.

Step-by-step explanation:

Given:

Job A -Sales- offers a base salary of $1,000 per week plus 3% commission on all sales above $3000.

Job B -Sales- offers a base salary of $1,100 per week plus 2.5% commission on all sales above $3000.

The total sales for the week equal $25,000.

Now, to find how much more money Job A pay than Job B.

Total sales = $25,000.

Job A pay:

Base salary = $1,000.

Base salary plus 3% commission on $25000.

$1000 + 3% of $25000.

= $1000+\frac{3}{100}\times 25000$

$=1000+0.03\times 25000$

$=1000+750$

$=1750.$

Job A pay = $1750.

Now,

Job B pay:

Base salary = $1,100.

Base salary plus 2.5% commission on $25000.

$1,100 + 2.5% of $25,000.

$=1100+\frac{2.5}{100}\times 25000$

$=1100+0.025\times 25000$

$=1100+625$

$=1725$

Job B pay = $1725

So, by deducting the salary of Job B from Job A we get the more amount:

$1750-1725\\=25$

Therefore, Job A pay $25 than Job B.
