Answer:

Step-by-step explanation:
We have the following variables:
y: hours of sleep
x: age
Each day, a young person should sleep 9 hours
This means that y is 9 added to something
plus 1 4 hour for each year that the person is under 18 years of age.
For each year the person is under 18 years of age, she should sleep 1/4 = 0.25h on top of the 9 hours.
So the equation relating hours of sleep y and age x is:

<span>Melvina's age is = x, Bettina's age is = 3x
the equation is
x + 20 = 3x - 20
subtract 3x from both sides
-(3x) + x +20 = 3x - 20 - (3x)
-2x + 20 = -20
subtract 20 from both sides
-2x + 20 - (20) = -20 - (20)
-2x = - 40
divide both sides by -2
(-2x)/-2 = (-40)/-2
x = 20
Melvinas age is 20 and Bettinas age is 60</span>
Answer:
<h3>There must be infinitely numbers different ones digits are possible in numbers that Larry likes.</h3>
Step-by-step explanation:
Given that my co-worker Larry only likes numbers that are divisible by 4, such as 20, or 4,004.
<h3>To find that how many different ones digits are possible in numbers that Larry likes:</h3>
From the given "Larry only likes numbers that are divisible by 4."
There are many numbers with one digits in the real number system that could be divisible by 4 .
<h3>We cannot say the count,so it is infinite.</h3><h3>Hence there must be infinitely numbers different ones digits are possible in numbers that Larry likes</h3>
Answer:
If im not incorrect the answer should be 5
