No on can explain it but it has a definition.
Given
Rob is twice Joshua's age
Nick is 5 years older than Joshua.
sum of all their ages is 45.
Find the age of nick.
To proof
As given
Rob is twice Joshua's age
let Joshua's age = x
than Rob age = 2x
Nick is 5 years older than Joshua.
Nick age = 5 + x
sum of all their ages is 45
than the equation becomes
Joshua's age + Rob age + Nick age = 45
put the value
x + 2x + 5 + x = 45
4x = 40
x = 10
Joshua's age = 10 year
than Rob age = 20 year
Nick age = 5 + 10
= 15year
Hence proved
I am guessing the answer is both
x=-0.834252 or x=0.134252
Answer:
A. y = 9√3
Step-by-step explanation:
The relationship of the sides of the triangles are as follows:
First leg = x
Second leg = x√3
Hypotenuse = 2x
Since we know the first leg is 9, multiply that by √3.
Therefore, y = 9√3.
Answer:
<em>is the increased number.</em>
Step-by-step explanation:
<em>The first step would be to turn the percentage into a decimal. To do that, divide it by 100.</em>
Then, multiply that by 90.
Add both together to get the increased price.
