Use PEMDAS.

P = Parentheses

E = Exponent

M = Multiplication

D = Division

A = Addition

S = Subtraction

This is the order of operations.

For example, let's take the second equation.

36 / 6 + 10 * 66

There are no parentheses or exponents.

So, first we multiply.

36 / 6 + 660

Then we divide.

6 + 660

Then we add.

666

So the equation equals 666.

lutik1710 [3]

Answer:

562 child tickets were sold

217 adult tickets were sold

Step-by-step explanation:

A festival charges $3 for children admission and $5 for adult admission

At the end of the festival they have sold a total number of 779 tickets for $2771

Let x represent the child ticket

Let y represent the adult ticket

x + y= 779..............equation 1

3x + 5y= 2771..........equation 2

From equation 1

x + y = 779

x= 779 -y

Substitute 779-y for x in equation 2

3x + 5y= 2771

3(779-y) + 5y= 2771

2337 - 3y + 5y= 2771

2337 +2y= 2771

2y= 2771 -2337

2y = 434

y = 434/2

y = 217

Substitute 217 for y in equation 1

x + y= 779

x + 217= 779

x = 779-217

x= 562

Hence 562 child tickets were sold and 217 adult tickets were sold
