Given : Andre drove 200 Miles using 9 Gallons of Gas

⇒ Andre drives 1 Mile using $[\frac{9}{200}]\;Gallons\;of\;Gas$

⇒ Andre drives (420 × 1 Mile) using $[\frac{420\times9}{200}]\;Gallons\;of\;Gas$

⇒ Andre drives 420 Miles using 18.9 Gallons of Gas

If a rectangle has a length of 5in, a width of 4in, and a height of 8in.Evaluate the volume using the formula: V=LWH 20 inches c

ozzi

Substitute the numbers in the equation:

$V=LWH$

Since L=5in, W=4in and H=8in:

$\begin{gathered} V=(5in)(4in)(8in) \\ =160in^3 \end{gathered}$

Therefore, the volume is equal to 160 inches cubed.

Choose the missing step in the given solution to the inequality −x − 10 > 14 + 2x. −x − 10 > 14 + 2x −3x − 10 > 14 ____

Svet_ta [14]

Answer: $-3x> 24$

Step-by-step explanation:

Given the inequality $-x - 10 > 14 + 2x$ , we need to solve for "x".

We can subtract $-2x$ to both sides:

$-2x-x - 10 > 14 + 2x-2x$

$-3x- 10 > 14$ (This step is shown in the exercise)

Now, we can add 10 to both sides:

$-3x- 10 +10> 14+10$

$-3x> 24$ (This step is not shown in the exercise)

And finally, divide both sides by -3:

$\frac{-3x}{-3}>\frac{24}{-3}$

$x< -8$ (This is shown in the exercise)

Therefore, the missing step is:

$-3x> 24$

stealth61 [152]

We can factor <span>4x^2-25 into (2x +5) * (2x -5) and
dividing by (2x -5)
yields (2x +5)

That neatened up pretty nicely.</span>
