-6(x+6)-10=-2(5+4x)

1 answer:

3 0

Assuming you need to solve for x:

-6(x + 6) - 10 = -2(5 + 4x)

start by distributing your numbers outside the front of your parentheses:

-6x - 36 - 10 = -10 - 8x

then combine like terms:

-6x - 46 = -10 - 8x ... add 10 to both sides (which technically could have cancelled out in the step prior, but regardless)
-6x - 36 = -8x ... add 6x to both sides
-36 = -2x ... divide both sides by -2
x = 18

How do i find the value of a variable?

photoshop1234 [79]

To find the value of a variable you must know the basics of pre-Algebra.

Example:

2x+9=39

To find he answer of this you must subtract 9 from both sides

Then you are left with…

2x=30

Since 2x=30 means 2 times x equals 30

You can divide 2 from both sides to find the answer

Which is…

x=15

The store bought the bike at a wholesale price. The bike store marked up the wholesale cost of the bike by 60%. What was the who

marin [14]

Answer: The wholesale cost of the bike = $100

Step-by-step explanation:

Let x = wholesale cost of the bike

As per given,

Selling price = cost price + (Mark up percent) x ( cost price) (i)

Selling price of bike = $160

Mark up percent = 60% =0.60

Substitute values in (i) , we get

$160= x+0.6x\\\\\Rightarrow\ 160=1.6x\\\\\Rightarrow\ x=\dfrac{160}{1.6}\\\\\Rightarrow\ x= 100$

Hence, the wholesale cost of the bike = $100
