Answer:
i think it means to just plot j at -6 on the x axis and 1 up on y axis
Answer:
Small boxes: 8
Large boxes: 11
Step-by-step explanation:
number of small boxes = x
number of large boxes = y
weight of boxes is represented by:
50x + 80y = 1280
Number of boxes is represented by:
x + y = 19
First, we'll solve for x in terms of y:
x = 19-y
Then we'll substitute that into the weight equation
50(19-y) + 80y = 1280
950 - 50y + 80y = 1280
30y = 330
y = 11
Now drop that numerical value into the number of boxes equation, and we'll get
x + 11 = 19
x = 8
Check the math in the weight equation:
50(8) + 80(11) =
400 + 880 = 1280
Let me know if you have any questions. Have a good evening!
Answer:6km
Step-by-step explanation:
Given
when Alice finishes the race Becky is 8km From finishing line
and caitlin 12 km from finishing line.
Suppose t is the time require by Alice to finish the race
and be the velocity of alice ,becky and caitlin
thus
thus
say t' is time required by beckey to complete 8 km thus
therefore for Caitlin
Thus caitlin will cover a distance of 6 km in t' time and 6 km away from finishing.
Answer:
64\ units^{3}
Step-by-step explanation:
we have
V=s^{3}
This is the formula to calculate the volume of a cube
where
s is the length side of the cube
In this problem we have
s=4\ units
substitute
V=4^{3}=64\ units^{3}
Answer:
its an limit number
Step-by-step explanation:
you can do it because its a limit number so this in't real
