I think it would be 300, because 15% of x=45, so .15x=45, x= 45/.15=300
Cube surface area = side^2 * 6
54 / 6 = side^2
side = sq root (9)
side = 3 centimeters
Answer: Prime
Step-by-step explanation: To tell if 37 is a prime number or a composite number, begin by finding the factors of 37.
To find the factors of 37, begin by dividing 37 by 1 which gives us 37. This means that 1 and 37 are factors.
Notice however that 37 is not divisible by any other number except 37. When we divide 37 by 37 we get 1. Since 37 and 1 are repeat factors, the only factors of 37 are 1 and 37.
When there are only two factors of a number, we call the number prime.
I think the answer would be none
Answer:
7y = x + 28
Step-by-step explanation:
Given x = 7t and y = t + 4
Here t is the parameter Now to remove it express one of it in terms of the variables (like x or y)
Given x = 7t
from this we can write ![t=\frac{x}{7}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7Bx%7D%7B7%7D)
Now substitute this value in the second equation
y = t + 4
![y=\frac{x}{7}+4](https://tex.z-dn.net/?f=y%3D%5Cfrac%7Bx%7D%7B7%7D%2B4)
Therefore the parameter is eliminated.
