Hi there!

Since the total weight the box can hold is 8 pounds, and she filled up 2/4:

8 * 2/4 = 4

There were 4 pounds in the box.

Hope this helps!

Solve: -rt - 80 > 30 for r. show your work!

vaieri [72.5K]

<h2>Steps:</h2>

So to solve for a variable, we must isolate it onto 1 side of the inequality. In this case, we must isolate r. Firstly, add 80 to both sides of the inequality:

$-rt>110$

Next, divide both sides by t:

$-r>\frac{110}{t}$

Next, multiply both sides by -1. Since we are multiplying by a <em>negative</em> number, flip the inequality symbol as well:

$r$

<h2>Answer:</h2>

<u>In short, your final answer is $r$ </u>

Which of the following is an equation of the line that passes through the point (5/3,-6) and has a slope of -3/4

ratelena [41]

Line through (a,b) with slope m is

y - b = m(x -a)

Here that's line through (a,b)=(5/3, -7) with slope m=-3/4

y - -7 = (-3/4) (x - 5/3)

Solve for y,

y + 28/4 = (-3/4) x + 5/4

y = (-3/4) x - 23/4

Look at the choices.

Answer: D
