Step-by-step explanation:
Giving the following information:
Dontae wants to buy 100 tiles for his kitchen floor. The tiles cost $2.35.
<u>To calculate the total cost, we need to use the following formula:</u>

Total cost= 2.35*100
Total cost= $235
Answer:
<h2>A. y = 3x - 2</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>y = mx + b</em>
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
<em />
We have
<em>A. y = 3x - 2 - it's the slope-intercept form</em>
<em>B. x = 1/2y + 8 </em><em>NOT</em>
<em>C. 2x + 5y = 12 </em><em>NOT</em><em> - it's the standard form</em>
<em>D. 3y = 8x - 5 </em><em>NOT</em>
Answer:
4/5 hour . . . . 48 minutes
Step-by-step explanation:
In hours, the total time is ...
... 1/10 + 1/5 + 1/2 = 1/10 + 2/10 + 5/10
... = (1+2+5)/10 = 8/10
... = 4/5

You can have a calculator add these numbers for you. Most will report the result as a decimal. There are fraction calculators on-line, if your graphing calculator does not have a fraction display mode.
If you want minutes, multiply the fraction (or decimal) by 60 minutes.
