Answer:

Step-by-step explanation:

Let "a number" = x

44 = 8x - 4

Simplify. Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First add 4 to both sides:

44 (+4) = 8x - 4 (+4)

44 + 4 = 8x

48 = 8x

Isolate the variable, x. Divide 8 from both sides:

(48)/8 = (8x)/8

x = 48/8

x = 6

6 is your answer.

At the movie theatre, child admission is $5.70 and adult admission is $9.75 . On Friday, 173 tickets were sold for a total sales

storchak [24]

Answer: 94 child tickets

Step-by-step explanation:

Let x represent child tickets

Let y represent adult tickets

Cost Equation: 5.70x + 9.75y = 1306.10

Quantity Equation: x + y = 173

Solve the system of equations using the elimination method:

Multiply the Quantity Equation by -5.70

5.70x + 9.75y = 1306.10

-5.70x - 5.70y = -986.10

4.05y = 320.00

÷4.05 ÷4.05

y = 79

x + y = 173

x + 79 = 173

x = 94

Distributive property pls helpp

Answer:

Step-by-step explanation:

If you consider matched parentheses to identify the contents of a "bag", the multiplier outside parentheses tells you how many bags you have. When you use the distributive property, you effectively dump all those bags on the table.

Here, the expression 4(6v +4) tells you there are 4 bags and each one contains 6v and 4. When you open them all up, you have ...

4(6v +4) = 6v +6v +6v +6v +4 +4 +4 +4

Of course, we can use multiplication to simplify repeated addition, so we can also write this as ...

4(6v +4) = 4·6v +4·4 = 24v +16

The numbers that go in your boxes are identified by their bold font style.
