<span>If x represents the year then that implies that y is equal to the number of new diseases every year. Therefore in order to solve this equation you need to input x. y= -2(15)^2 + 36(15) +6 Now solve, but please remember to use PEDMAS order in order to solve this problem. P= Parentheses E= Exponents D = Division M= Multiplication A= Addition S= Subtraction So solve the parentheses first y= -30^2 + 540 + 6 Now the exponent. y= 900 + 540 + 6 Now add them all together. y= 1446 So 1,446 is the number of new cases in year 15. y=</span>

a teacher had 21 red pens. if the ratio of red pens to blue pens she owned was 3:1 , how many pens did she have in total
erma4kov [3.2K]
There are 21 red pens. For every 3 red pens, there is 1 blue pen.
Let's make these into a fraction equation.
21/p=3/1
p is the number of blue pens we have yet to find.
First, cross multiply.
21x1=21
px3=3p
Now, we have an equation of
21÷3p
We set it equal to 1, and we solve it.
21÷3p = 1
(21÷3p)×3p=1×3p
21=3p
21÷3=(3p)÷3
7=p
So, if there are 21 red pens, there are 7 blue pens.
We add these together to find the total number of pens the teacher has.
21+7=28
The teacher has 28 pens total.
