Law Incorporation [45]

The volume of a cube is just the side length cubed...

V=s^3 in this case:

V=39^3=59319 ft^3

and in cubic yards it is:

59319 ft^3*(yd^3/27 ft^3)=2197 yd^3

A total of 676 tickets were sold for the school play. They were either adult tickets or student tickets. There were 74 fewer stu

katen-ka-za [31]

To find the answer,we can solve this by settin up an equation.

Let x be the number of adult tickets sold.

The number of students ticket sold would be:
x-74

We can then sum them up to set an equation:

x+x-74 = 676
2x = 676 + 74
x = 375

Therefore the adult tickets sold were 375.

Hope it helps!

For the following exercises, determine whether the functions are even, odd, or neither.

Answer:

The solutions of the equation |2 x-3|=17

are x=10

and x=-7

Step-by-step explanation:

Given equations is |2 x-3|=17.

It is required to find out the values of x satisfying the given equation.

To find it out, use the fact that the solution of this type of equation is 2x-3=17.

Or 2x-3=-17 and simplify the equations using simple mathematical operations.

Step 1 of 2

Solve the equation 2x-3=17,

Add 3 on both sides of the equation 2x-3=17,

2x-3+3=17+3

2x=20

Divide by 2 on both sides of the equation 2x=20,

$\begin{aligned}&\frac{2 x}{2}=\frac{20}{2} \\&x=10\end{aligned}$

Step 2 of 2

Solve the equation 2x-3=-17,

Add 3 on both sides of the equation 2x-3=-17,

$2 x-3+3=-17+3$\\ $2 x=-14$

Divide by 2 on both sides of the equation 2x=-14,

$\begin{aligned}&\frac{2 x}{2}=\frac{-14}{2} \\&x=-7\end{aligned}$
