Answer:
a) 7 : 20
b)There will be 35 people with blue eye
Step-by-step explanation:
a)
This question is asking you the ratio of the number of people with blue eyes to the total number of people.
So seven people with blue eyes to the total number of 20 people.
7 : 20
b)
you got the ratio 7 : 20, this also means that there will be 7 people with blue eyes in every 20 people.
so you use 100 divides by 20, you will get the number five, this means there are 5 groups of 20 in 100 people.
so then you use 5 times 7, then you got the number 35.
That means, there are 35 people with blue eyes in 100 people.
The inverse for this operation would be to find the equation for "x" since it's the equation for "y." Inverse means reverse in direction or position. To find the inverse of "y = -3/(x+4) , you would need to start by using the order of operations. Here's where you start:
y<span> = -3/(x+4)
</span>
Next, you want to get the (x+4) to the other side. Since it's being divided, multiply this number on both sides.
y = -3/(x+4) ⇒ (x+4)y = -3
Now, you need to get y on the opposite side. Divide both sides by y.
(x+4)y = -3 ⇒y÷ (x+4)y = -3 ÷ y
The y's cancel on the left, so you would have the equation:
x+4 = -3/y
Now to get x by itself, subtract 4 from both sides.
x+4 = -3/y
-4 -4
⇒x = -3/y -4 is your final answer.
