Rewrite the equation below so that it does not have fractions. 3/4x+2=5/6 do not use decimals in your answer.

mafiozo [28]

Answer:

18x + 48 = 20

Step-by-step explanation:

Rewrite the equation below so that it does not have fractions. 3/4x+2=5/6 do not use decimals in your answer.

We are given the expression:

3/4x + 2=5/6

= 3x/4 + 2 = 5/6

Rewriting the Equation so that it does not have fraction is, we Multiply both sides by the 24

= 3x/4 × 24 + 2 × 24 = 5/6 × 24

= 3x/4 × 24 + 48 = 5 × 4

= 3x × 6 + 48 = 20

= 18x + 48 = 20

Therefore, the Equation without fractions = 18x + 48 = 20

7x – 5x – 3 = x + 4.

Sophie [7]

What you need to do is cancel everything to the left of the equal sign. Solve that problem.. The answer to that is 0. So what, plus 4 equals 0? -4

two coplanar lines that are perpendicular to the same line are parallel. a) always b) sometimes c) never

sergeinik [125]

<u>Answer:</u>

Two co planar lines that are perpendicular to the same line are always PARALLEL. So option A is correct.

<u>Explanation:</u>

Given:

Two lines are coplanar.

They are perpendicular to the same line

To find:

whether they are parallel or not and choose the correct option from the given options.

Solution:

Now, we know that, slopes of perpendicular lines is -1

Then, $\text{{slope of 1st line}}\times \text{{slope of perpendicular line}} = -1$

$\text{{slope of perpendicular line}} =\frac{- 1}{\text{{1st line slope}}}$

similarly

$\text{{slope of 2st line}}\times \text{{slope of perpendicular line}} = -1$

$\text{{slope of perpendicular line}} =\frac{- 1}{\text{{2st line slope}}}$

Now, as both lines are perpendicular to same line, then, we have to equate above both of them.

Then, $\frac{- 1}{\text{{1st line slope}}}= \frac{-1 }{\text{{2nd line slope}}}$

1st line slope = 2nd line slope

Here, slopes of two lines are equal.

Hence, Two coplanar lines that are perpendicular to the same line are always parallel. So option A is correct.
