The mean is 2.5. also there is mean, median, mode calculators online to help you with these in the future
First let’s express the total number of marbles as such:
y(yellow marbles) + r(red marbles)=23; y+r=23
now let’s express the relation of yellow marbles to red marbles:
y=2r(2 times red marbles) - 4(4 less marbles); y=2r-4
since we figured out what y equals, we can plug into the first equation we created:
(2r-4)+r=23
now solve for r:
2r-4+r=23
combine like terms
3r-4=23
add 4 to both sides
3r=27
divide both side by 3
r=9
plug r back into first equation and solve for y:
y+9=23
subtract 9
y=14
there are 9 red marbles and 14 yellow marbles!
Answer:
the Answer is 150x + 12100 ≤ 26500
Step-by-step explanation:
The max weight is 26500 so the weight would have to be the same or less than 26500 (≤)
There is already 12100 killograms on the sipping containter so that is why you have + 12100
and you have 150x because x is the number of 150-kilogram crates
and for as many crates you have to multiply by the weight.
