Answer:

Step-by-step explanation:

The order of operations is applicable in a multip-operations equation. This theorem states the order in which one must do operations in order to get a valid result. Remember the order of operations states;

1) Parenthesis

2) Exponents

3) Multiplication or Division

4) Addition or Subtraction

Solve this equation, keeping the order of operations in mind;

{ [ 3 + 2 - ( 9 - 7 ) + ( 3 + 4 ) ] }

{ [ 3 + 2 - ( 2 ) + ( 7 ) ] }

{ [ 3 + 2 - 2 + 7 ] }

{ [ 5 - 2 + 7 ] }

{ [ 3 + 7 ] }

{ [ 10 ] }

Mr. Smith's $85,000 condominium is assessed at 35% of value. The tax rate is $2.70 per $100 of value. If the tax increases $.35

wel

Answer:

$907.38

Step-by-step explanation:

We have been given that Mr. Smith's $85,000 condominium is assessed at 35% of value.

First of all, we will find 35% of $85,000 as shown below:

$\frac{35}{100}\times \$85,000$

$35\times \$850$

$\$29,750$

We are also told that the tax rate is $2.70 per $100 of value. Now we will divide $29,750 by 100 as:

$\frac{\$29,750}{\$100}=297.50$

Since the tax rate is increased by $0.35 per $100 of value, so the new tax rate will be $2.70 plus $0.35.

$\text{New tax rate}=\$3.05$

$\text{Amount of new tax}=\$3.05\times 297.50$

$\text{Amount of new tax}=\$907.375$

$\text{Amount of new tax}\approx \$907.38$

Therefore, Mr. Smith's new tax will be $907.38.

Minnie organizes data in a table to show the net change in the number of people subscribing and unsubscribing to her Website eac

maw [93]

Answer:

4( -1 -11 )+2 (17)

-14

Step-by-step explanation:

This one requires more abstract thinking than you'd expect!

So essentially you want to count up how many -11's there are, -1's and 17's.

There are four -11's and four -1's, and two 17's.

So that means 4 x -11 + 4x-1 + 2x17 = The Total Sum of Subscribers

We can "factor out" a 4 from the -11 and -1.

4( -1 - 11) + 2(17)

So then you'd solve that and get

-14

How is 5/2 divided by 1/4 equals 10 responsible

vredina [299]

Answer:

Step-by-step explanation:

'll just help with proving whether she is correct.

First of all, a fraction divided by a fraction can be made into multiplication since the division of two fractions is kinda difficult

so remember keep, change, flip

keep the first fractions, change the division symbol into multiplication, then flip the fraction i.e. 1/2 becomes 2/1

so 5/2 divided by 1/4 becomes

5/2 * 4/1

which then solved becomes

20/2 which is simplified to 10

Hope this helps :)

Answer:

The final answer is-925x+3

Step-by-step explanation:

The problem to solve is:

3-5x10-7x125

Multiply x and 5

Multiply x and 1

The x just gets copied along.

The answer is x

5*x evaluates to 5x

Multiply 10 and 5x

Multiply 1 and x

The x just gets copied along.

5*x*10 evaluates to 50x

3-5*x*10 evaluates to 3-50x

Multiply x and 7

Multiply x and 1

The x just gets copied along.

The answer is x

7*x evaluates to 7x

Multiply 125 and 7x

Multiplying 1 and x

The x just gets copied along.

7*x*125 evaluates to 875x

-50x - 875x = -925x

The answer is -925x+3

3-5*x*10-7*x*125 evaluates to -925x+3

The final answer is-925x+3

The problem to solve is:

15-5x6-7

Multiply x and 5

Multiply x and 1

The x just gets copied along.

The answer is x

5*x evaluates to 5x

Multiply 6 and 5x

Multiply 1 and x

The x just gets copied along.

5*x*6 evaluates to 30x

15-5*x*6 evaluates to 15-30x

15 - 7 = 8

The answer is 8-30x

15-5*x*6-7 evaluates to 8-30x

The final answer is8-30x
