Answer:
515x + 285y = 11,080
x + y = 30
Step-by-step explanation:
x= Amount of laptops
y= Amount of tablets

Answer:</h2>
<u>The mean altitude will be</u><u> -54 per minute</u>
<h2>
Step-by-step explanation:</h2>
We are given with altitude change as -378 feet over 7 minutes
Now
We need feet per minute
So -378 / 7 will give us the altitude change per minute
-378 / 7 = -54
Therefore the mean change of altitude in feet per minute is -54 per minute
Answer:
y = -2x + 4
Step-by-step explanation:
First find slope:
We know equation of a line is y = mx + b, where m = slope and b = y-intercept, so we can plug in the slope:
y = -2x + b
The y-intercept of the equation is 4 because the coordinate (0, 4) is given. Therefore, the equation is:
y = -2x + 4
Because 5x6 is 30 that is plenty for 27 kids but 5x5 is only 25, that is not enough for 27 kids.
