What value of x makes the equation -6x-20=-2x+4 (1-3×) true​

Mathematics
1 answer:
dmitriy555 [2]3 years ago
4 0

Answer:

x = 3

Step-by-step explanation:

-6x - 20 = -2x + 4 (1 - 3x)

Distributive property

-6x - 20 = -2x + 4  - 12x

Combine like terms

-6x - 20 = -14x + 4  

Add 14x to both sides

-6x - 20 + 14x = -14x + 4  + 14x

Simplifying

8x - 20 = 4

Add 20 to both sides

8x = 24

Divide both sides by 8

x = 3

A car dealership buys a car for $12,500. They sell the car for $15,750. What is the percent markup?
Elodia [21]

Answer: 26%

Step-by-step explanation:

The formula to calculate the percentage markup is given as:

= Selling price - Cost / Cost price × 100

where selling price = $15750

Cost price = $12500

Percentage markup = ($15750 - $12500) / $12500 × 100

= $3250/$12500 × 100

= 26%
