write an equation with the solution x=20. The equation should have the variable on both sides, a fractional coefficient on the left side, and a fraction anywhere on the right side

Answers

Answer 1

Answer:

Answer:

$(8)/(7)x=(20)/(7)+x$

Step-by-step explanation:

The given equation is

$x=20$

We need to write an equation that should have the variable on both sides, a fractional coefficient on the left side, and a fraction anywhere on the right side.

Multiply both sides by 1/7 in the given equation.

$(1)/(7)* x=(1)/(7)* 20$

$(1)/(7)x=(20)/(7)$

Add x on both sides.

$(1)/(7)x+x=(20)/(7)+x$

$(8)/(7)x=(20)/(7)+x$

This equation have the variable x on both sides, a fractional coefficient 8/7 on the left side, and a fraction 20/7 on the right side.

Therefore the required equation is $(8)/(7)x=(20)/(7)+x$ .

Answer 2

Answer: 1/2x+9=2x/2-1. I hope this meets ur criteria. It works and equals 20.

Given:

A number is selected at random from the numbers 1 to 25.
Each of the given numbers is equally likely to be selected.

To Find:

Probability that the number is not a prime number.

Solution:

Required Sample space of the following event ( Non- prime numbers between 1 to 25 )

$\dashrightarrow$ 1, 4, 6, 8,9 10,12, 14, 15, 16,18, 20, 21, 22, 24, 25

Number of Favourable Outcomes = 16

Total number of outcomes = 25

Now as we know

Probability of an event =

$\star\;\boxed{\sf{\pink{( Favourable\; number\;of\; outcomes)/(Total\; number\;of\; outcomes)}}}$

Probability = 16/25

Hence, probability that the number is not a prime number is 16/25.

Answer:

Favourable outcomes = {1,4,6,8,9,10,12,14,15,16,18,20,21,22,24,25}

Number of favourable outcomes=16

Number of total possible outcomes=25

p(not a prime) = (number of favourable outcomes) / number of total possible outcomes

=16/25

What is the slope of a line parallel to the line y=3x-4=8y+1

Answers

The slope of any line parallel to y = 3x - 4 is also 3.

The given equation is y = 3x - 4 , I will assume you meant to write:

y = 3x - 4

To find the slope of a line parallel to this line, we can observe that parallel lines have the same slope. The equation of the given line is in the slope-intercept form y = mx + b, where "m" represents the slope. In this case, the slope (m) of the line is 3.

So, the slope of any line parallel to y = 3x - 4 is also 3.

Answer: If the original equation is y = 3x -4, the slope is 3.

Any equation of a line parallel to the line y = 3x -4 will have a slope of 3.

Step-by-step explanation:

In slope-intercept form, y =mx + b the coefficient of x, m is the slope.

Here 3 is that value.

It is very unusual to have two equal signs in a question about slope.

I am not sure what to do with the =8y + 1

Is this supposed to be another equation in the system, missing a term?

I dont know how to do this... Please help :)
