Answer:
it's either B=6.25-1.25r or it's r=5-0.8b
Answer:
20
Step-by-step explanation:
If you work this out you get 1:
5/100*20
5 divided by 100 is 0.05 then 0.05 times 20 is 1
15+c=17.50
First you subtract 15 by 15 because you switch operations from adding to subtracting then you would put C under it
Second subtract 17.50 and 15 and that is 2.50 so C= 2.50
Answer:
684
Step-by-step explanation:
Using proportions (equivalent ratios), we can find the number of students that make up the 57% out of the total number of people:
Cross-multiply: 100x = (57)(1200) or 100x = 68,400
Divide: 100x/100 = 68,400/100
Solve for x: x = 684 students
Here you have an equation with two unknown constants, a and b, plus 2 sets of points through which the graph goes.
Second point: 96 = a(b)^2
First point: 6 = a(b)^0 Then a = 6.
With a = 6, we can now write: 96 = 6b^2. Then b^2 = 16, and b=4.
Then y =6(4)^x (answer)
