If 2/3 of a certain number is subtracted from twice the number, the result is 20. Find the number.

2 answers:

6 0

Answer: 60
Step by Step Explanation:
Let the number be x
So, x-2/3x=20
=> x/1 - 2/3x = 20
=> (3x - 2x)/3 = 20
=> x/3 = 20
=> x= 20*3
=> x=60
Checking if the solution is correct:
So substitute the value of x in x-2/3x=20
As we know x=60
So, => 60 - 2/3*60 = 20
=> 60 - 40 = 20
As 20 = 20
So this answer is correct

Let x be the number.

Set up an equation:

2x - 2/3x = 20

Simplify:

1 1/3x = 20

Divide both sides by 1 1/3

X = 15

The number is 15

(-1,-2) and (3, -162) a. Is there a line th(at goes through these two points? How do you know? If there is one, what is the equa

Answer:

The equation of line for given points is y = - 40 x - 42

Step-by-step explanation:

Given two points as :

( -1 , - 2 ) and ( 3 , - 162 )

Now, Equation of line in points form

y - $y_1$ = m × ( x - $x_1$ )

Where m is the slope of line

And, m = $\frac{y_2 - y_1}{x_2 - x_1}$

or, m = $\frac{ - 162 + 2}{ 3 + 1}$

or, m = $\frac{ - 160}{ 4}$

∴ m = - 40

So, Slope of line for given points is - 40

Now equation of line can be written as

y - ( - 2 ) = ( - 40 ) × ( x - ( - 1 ) )

or, y + 2 = ( - 40 ) × ( x + 1 )

or, y + 2 = - 40 x - 40

or, y = - 40 x - 40 - 2

∴ y = - 40 x - 42

Hence the equation of line for given points is y = - 40 x - 42 Answer

It costs $3.56 to buy a pack of pencils. Which of the following equations shows the amount of money needed, x, to buy k packs of

FrozenT [24]

Well, since we know $3.65 is how much ONE PACK of pencil costs, and k represents the packs of pencils PURCHASED, and x represents the COST per pack, your answer would be A. x = 3.65k. This is because to find out the total cost (x) of k amount of packs, you would multiply the cost (3.65) times k, (known as 3.65k), which would be expressed as x = 3.65k. =)
Hope I helped! ^-^
