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

Researchers collected data from 100 randomly chosen counties in Texas on pollution levels and asthma rates. Pollution levels wer

lesya692 [45]

Answer:

The answer is "3.14".

Step-by-step explanation:

The coefficient of pollution level is "b" and "a" intercept

$\to y=a+bx\\\\$

We must verify it.

$H_0 :\beta = 0\\\\H_a : \beta \neq 0\\\\$

$Beta \to b=1.76, SE=0.56 \ Estimate$

The statistics on tets are now provided

$\to t=\frac{b}{SE}=\frac{1.76}{0.56}=3.14$

Because statistics will be more than critical $(1.984)$ values, we thus reject $H_0$

Which of the following are solutions to the equation below?

anastassius [24]

Answer:

C and F

Step-by-step explanation:

Given

(3x - 5)² = 19 ( take the square root of both sides )

3x - 5 = ± $\sqrt{19}$ ← note plus or minus

Add 5 to both sides

3x = ± $\sqrt{19}$ + 5 ( divide both sides by 3 )

x = ± $\frac{\sqrt{\sqrt{19}+5 } }{3}$

Separating the solutions

x = $\frac{\sqrt{19}+5 }{3}$ → C

x = $\frac{-\sqrt{19}+5 }{3}$ → F
