Hey there!
Let's create a systems of equations with x and y to find our numbers.
x=5y
x-y=1480
Let's plug our x value into the second equation.
5y=y=1480
4y=1480
y=370
Now we multiply this number by five as the first equation says to get our x.
x=1850
Our numbers are 1850 and 370.
I hope this helps!
Well, you would have to multiply 8 by whatever factorial of 3, in this case 4 for the number of weeks
The equation is 8 x 3^4 which equals 648
My only thing is that they only triple in SIZE, and not multiply (as in make more of themselves) so technically speaking, there would still be 8 bacteria, just much bigger
Answer:
143
Step-by-step explanation:
180 - 37 = 143.
We know this because y + 37 = 180
so we can does 180-37 to get our answer.
Answer:
Each student; 32
Kevin; 12
Step-by-step explanation:
4% of 800 is 32. Each student is responsible for colleting 32 box tops.
The next step is to figure out what 37.5% of the 32 is 12.
Hope that this helps! Have a good day and good luck!
D=number of drinks
p=number of bags of popcorn
75=6d+8p
100.50=12d+10p
multiply first equation by -2 and add to first
-49.50=-6p
divide -6
8.25=p
sub
100.50=12d+10p
100.50=12d+82.50
minus 82.50
18=12d
divide 12
1.50=d
