The sum of 3 times a number and 7, divided by 5, is 17 written as an equation
Anestetic [448]

Equation is: \frac{3x+7}{5}=15

and Value of x is x=68/3\\

Step-by-step explanation:

We need to write an equation of:

The sum of 3 times a number and 7, divided by 5, is 17

Let the number = x

So, equation will be:

\frac{3x+7}{5}=15

We can solve the equation to find the value of x.

\frac{3x+7}{5}=15\\3x+7=15*5\\3x+7=75\\3x=75-7\\3x=68\\x=68/3\\

So, Equation is: \frac{3x+7}{5}=15

and Value of x is x=68/3\\

Carnival M charges an entrance fee of $5.00 and $0.65 per ticket for the rides. Carnival P
MA_775_DIABLO [31]
25 tickets

I put the information into this equation 5+0.65x=10+0.45x

I solved the equation by first subtracting the 0.45x from both sides to get the variable on one side. I was left with 5+0.20x=10. Then I subtracted the 5 from both sides and got 0.20x=5. Finally I divided both sides by 0.20 to get the X by itself and got X=25

Explain why y^2 = x (X input, y output) is not a function.
sveta [45]

y^2 = x isn't a function because there is at least one value of x that produces multiple values of y. In fact, any x value greater than 0 yields two y values. If x = 0, then y = 0 is the only solution. ... Graphically, the equation fails the vertical line test, which is another way to determine that it is not a function.
