If 2x + 5 = 8x, then 12x = ?A.5B.10C.15D.20

butalik [34]

<h2>Answer:</h2> $10.\text{ Option B is correct}$

<h2>Explanation:</h2>

Given the equation expressed as:

$2x+5=8x$

First, we need to calculate the value of "x" from the given expression.

Step 1: Given the equation 2x + 5 = 8x

Step 2: Subtract 5 from both sides:

$\begin{gathered} 2x+5-5=8x-5 \\ 2x+\cancel{5}-\cancel{5}=8x-5 \\ 2x=8x-5 \end{gathered}$

Step 3: Subtract 8x from both sides

$\begin{gathered} 2x-8x=8x-8x-5 \\ -6x=\cancel{8x}-\cancel{8x}-5 \\ -6x=-5 \end{gathered}$

Step 4: Divide both sides by -6

$\begin{gathered} \frac{-6x}{-6}=\frac{-5}{-6} \\ x=\frac{5}{6} \end{gathered}$

Step 5: Get the value of 12x. Substitute x = 5/6 into the expression to have:

$\begin{gathered} 12x=12(\frac{5}{6}) \\ 12x=\cancel{12}^2(\frac{5}{\cancel{6}^1}) \\ 12x=2\times5 \\ 12x=10 \end{gathered}$

Therefore the value of 12x is 10

What is -7 2/3 + (-5 1/2) + 8 3/4

Veseljchak [2.6K]

Hey there :)

$-7 \frac{2}{3} = - \frac{23}{3}$
$-5 \frac{1}{2} = -\frac{11}{2}$
$8 \frac{3}{4} = \frac{35}{4}$

$- \frac{23}{3} - \frac{11}{2} + \frac{35}{4}$

We need to change all fractions to have a common denominator

Lets see:
Multiples of 2: 2 , 4 , 6 , 8 , 10 , 12
Multiplies of 3: 3 , 6 , 9 , 12
Multiplies of 4: 4 , 8, 12

The common denominator is 12
2 x 6 = 12
3 x 4 = 12
4 x 3 = 12

= $-\frac{23(4)}{3(4)} - \frac{11(6)}{2(6)} + \frac{35(3)}{4(3)}$
= $- \frac{92}{12} - \frac{66}{12} + \frac{105}{12}$

We need to add the numerators while keeping the same denominator
= $- \frac{53}{12}$
= $-4 \frac{5}{12}$
