Answer:
36/55
Step-by-step explanation:
convert the mixed numbers into improper fractions
=12/5 / 11/3
multiply fractions
=12x3/5x11
=36/55
No pictures. No help. Sorry... But thanks for the points.
Answer:
Given that,
The function is,
To find: To find the slope of the secant line from x1=0 and x2=4
Explanation:
First we find the corresponding y values that is y1 and y2 for the given x1 and x2 respectively.
we get,
Whwn x1=0,
When x2=4, we get,
To find the slope of the line passing the points (0,555), (4,1099.8)
we know that,
Slope of the line passing through the points (x1,y1) and (x2,y2)
we get,
Answer is:
Slope of the secant line from x1=0 and x2=4 is 136.2.
Answer:
140
Step-by-step explanation:
46+94 = 140
Call the notebooks x, and the pencils y.
<span>3x + 4y = $8.50 and 5x + 8y = $14.50 </span>
<span>Then just solve as simultaneous equations: </span>
<span>3x + 4y = $8.50 </span>
<span>5x + 8y = $14.50 </span>
<span>5(3x + 4y = 8.5) </span>
<span>3(5x + 8y = 14.5) </span>
<span>15x + 20y = 42.5 </span>
<span>15x + 24y = 43.5 </span>
<span>Think: DASS (Different Add, Similar Subtract). 15x appears in both equations so subtract one equation from the other. Eassier to subtract (15x + 20y = 42.5) from (15x + 24y = 43.5) </span>
<span>(15x + 24y = 43.5) - (15x + 20y = 42.5) = (4y = 1) which means y = 0.25. </span>
<span>Then substitue into equation : </span>
<span>15x + 20y = 42.5 </span>
<span>15x + 5 + 42.5 </span>
<span>15x = 42.5 - 5 = 37.5 </span>
<span>15x = 37.5 </span>
<span>x = 2.5 </span>
<span>15x + 24y = 43.5 </span>
<span>15(2.5) + 24(0.25) </span>
<span>37.5 + 6 = 43.5 </span>
<span>So x (notebooks) are 2.5 ($2.50) each and y (pencils) are 0.25 ($0.25) each.</span>
