Answer:

a. 12a + 3b

b. 5b + 3a

Step-by-step explanation:

Which terms have the same thing applied to them? This is what I ask myself while figuring these out.

a. 5 and 7 both are multiplied by a, so you can combine the expressions to make 12a.

b. 10b - 5b = (10 - 5)b

Both 10 and 5 are multiplied by b, so you can just subtract the integers to get 5b.

I hope this helped!

A. So you see you have a and b. You can only add the same letters. For example in this problem, you add 5a+ 7a because they are the same so you get 12a. 3b stays the same because there is no other number with b. So the answer would be 12a+3b.

B. Just like in the last problem. You would do 10-5 because they both have b. So it would be 5b+3a

In Britain a Value Added Tax (VAT) of 17% is added to most purchases. If a skit costs $58.50 including tax, what is the price of the skirt before tax?

Answers

Answer:

i think it is 45.70

Step-by-step explanation:

Answer:

$48.55

Step-by-step explanation:

Make 17% into a decimal Multiply 0.17 and the number of Britain Value including tax Then take that number and subtract it by the number of Britain Value including tax

Equation:

17% = 0.17

Why? The symbol % is called the percent sign. The expression 17% means 17 parts out of 100. Therefore, 17% is equivalent to the common fraction and to the decimal fraction 0.17.

0.17 × (Britain Value Including Tax) 58.50 = 9.945 to be exact but I rounded it up to 9.95 for easier use

58.50 - 9.95 = 48.55

So $48.55 is your answer

I hope this helped! Brainliest highly appreciated! Tell me if this is wrong I would like to know :) All of this written and solved by me. Except for the italic explanation of how to make 17% a decimal. You are free to use this explanation if needed so don't feel hesitant to copy and paste this.

Answers

Answer:

0 Start at the origin. Move 7 units to the right, then move 4 units up.

Please help me with this question! Dinner at TGI Friday's costs $50 for your family. Find your total cost if the sales tax is 6% and you leave a 15% tip on the total bill. Round to the nearest cent if necessary.

(Remember, some people tip on the cost of the meal, and some people tip on the total with tax. In this case, it is clear that we are tipping on the cost plus tax because it says "total bill." This means we need to treat it as a two-step problem.)

Answers

First start off by doing 6% of 50 which is 3, add it to the total making 53. Then you do 15% of 53 which is 7.95 making your total $60.95
