Answer:
<em>We</em><em> </em><em>can</em><em> </em><em>say</em><em> </em><em>that</em>
<em> </em>3x + x + 8 = 32
<em>So</em><em>:</em><em> </em>
3x + x + 8 = 32
4x = 32 - 8
4x = 24
x = 24/4
<em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>6</u></em>
Answer:
D. 360 in.²
Step-by-step explanation:
<em>Since all the answers are labeled as in.², we know that we have to find the area of the rectangular prism. The formula for area of a rectangular prism is: </em><em>lwh </em><em>(length x width x height).</em>
<em>l = 12</em>
<em>w = 6</em>
<em>h = 5</em>
12 x 6 x 5 = 360
Answer:
3 3/5 minutes
Step-by-step explanation:
Let one measure of volume be 5/9 of a tank, or (5/9)(tank).
We're interested in filling the whole tank, which we represent by (1)(tank) or (9/9)(tank.
Write and solve an equation of ratios:
(5/9) (tank) 2 minutes
------------------- = ----------------
(9/9) (tank) x
Solve for x, which represents the number of minutes required to fill the whole tank:
(5/9)(x) = (9/9)(2), or (after simplifying) 5x = 18, or x = 18/5 (3 3/5 minutes)
The whole tank will be filled in 3 3/5 minutes.
