Answer:
These are the forms to write the ratio. Please read the explanation.
<u>a. 3/4</u>
<u>b. 3:4</u>
<u>c. 3 ÷ 4</u>
<u>d. Ratio of 3 to 4</u>
Step-by-step explanation:
1. Let's check the information given to resolve the question:
Number of 13-year olds = 36
Number of 14-year olds = 48
2. Writing the ratio of 13-year-olds to 14-year olds in all three forms:
We can say that there are:
36/48 13-year olds to 14-year olds but we notice immediately that we can simplify that ratio this way:
36/48 = 18/24 (Dividing by 2) = 9/12 (Dividing by 2 again) = 3/4 (Dividing by 3)
We can conclude that the ratio of 13-year-olds to 14-year olds is 3/4 and we can write it these ways:
<u>a. 3/4</u>
<u>b. 3:4</u>
<u>c. 3 ÷ 4</u>
<u>d. Ratio of 3 to 4</u>
Answer:
2i
Step-by-step explanation:
Distribute:
(5y + 2)(y - 3)
5y^2-15y+2y-6
Which can be simplified into 5y^2-13y-6
Now the equation now looks like this: 5y^2-13y-6=-13(2+y)
For -13(2+y) multiply -13 with 2+y
Which is -26-13y
5y^2-13y-6=-26-13y
Simplify:
5y^2+20
Which can be simplified into 5(y^2+4)
y^2+4=0
y^2=-4
y=2i
Hope this helps!
