Find the nonpermissable replacement for the variable in this expression 3x over 5x+2

kotegsom [21]

5x + 2 is a denominator.
A denominator cannot equal zero since division by zero is undefined.
Set the denominator equal to zero and solve for x to find which value of x makes the denominator zero.

5x + 2 = 0

5x = -2

x = -2/5

The non-permissible replacement for the variable is -2/5.

How do you determine volume?

bulgar [2K]

Answer: V = πr 2 h

Step-by-step explanation:

To calculate the volume of a cylinder, you must know its height and the radius of the circular base (the distance from the center of the circle to its edge) at the top and bottom. The formula is V = πr 2 h, where V is the Volume, r is the radius of the circular base, h is the height, and π is the constant pi.

MatroZZZ [7]

Answer:

Emily spend $12 on lunch.

The correct option is Option A i.e 23 plus x equals 35; x equals 12

Step-by-step explanation:

Let amount spent on Lunch = x

Total money Emily brought to the fair = $35

Money Spend on ride tickets and lunch = 16+x

Money Left with Emily = $ 7

We need to find how much Emily spend on lunch

SO,

We can write the equation $16+x+7=35\\$

As, total money is 35 and $7 are still with emily

Solving to find value of x

$16+x+7=35\\x+23=35\\x=35-23\\x=12$

So, Emily spend $12 on lunch.

The correct option is Option A i.e 23 plus x equals 35; x equals 12
