Answer:
15
Step-by-step explanation:
Red : Blue :
3 8
We have 40 blue marbles
Multiply 8 by what to get 40
40/8 =5
So we need to multiply by 5
Red : Blue :
3*5 8*5
15 40
There are 15 red marbles
36.89 total divided by the 8.6 gallons he bought = 4.2 so the price per gallon would be $4.20
You need two pieces and 1 has to be 2x longer than the other
set x as the smaller piece (easier to always go with the smaller value as x)
the other piece is 2x (double in size)
your equations would be 3x=240>>> x= 60
so smaller piece/ x= 60
bigger piece/ 2x= 120
Answer:
x = 118
Step-by-step explanation:
I would say you would subtract 180 minus 76 because a straight line equals 180 if I’m wrong I’m sorry
