Answer:
There is an 25% chance of getting a red marble
Step-by-step explanation:
4+3+5=12
3/12=.25
put the decimal over two spaces and you get 25%
a=112
b=6
c=280
you just plug the number into the equation
28x=y
where x is the gallons
and y is the total miles
Answer:y=-4
30×3=90 10×9=90 45×2=90 . .
15, 17, 19, and 21
make the equation
x+x+2+x+4+x+6=72
simplify
4x+12=72
x+3=18
x=15
