The box has volume
11 in × 3 in × <em>x</em> in = 33<em>x</em> in³
and surface area
2 (11 in × 3 in + 11 in × <em>x</em> in + 3 in × <em>x</em> in) = (66 + 28<em>x</em>) in²
The volume and area have the same value if
33<em>x</em> = 66 + 28<em>x</em>
Solve this equation for <em>x</em> :
33<em>x</em> - 28<em>x</em> = 66
5<em>x</em> = 66
<em>x</em> = 66/5 = 13.2
460= 40+ 12x
X equal the cost per month, which is what we're looking for.
460=40 +12x
-40 -40
420=12x
420/12= 35
So they would pay $35 per month with the $40 fee, as seen in the $460 fee.
Answer:
2/3
Step-by-step explanation:
1/3 multiplied by 2 equals 2/3
Which is the larger proportion, 0.28 or 0.25?
Answer:
<h2>y = 2x + 5</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
We have the equation of a line in the standard form.
Convert to the slope-intercept form:
<em>add 2x to both sides</em>
