Answers

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.

To graph the point (4, -7) on the coordinate plane, start at the origin. Move 4 units _______ and 7 units ________ .
choices:
a
right.....down
b
left....down

Answers

Answer:

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

Step-by-step explanation:

You go in before you go up, the first number always goes either right or left, depending on if it's negative or positive, and the second number goes up or down, depending on if it's negative or positive.

The answer is “a” because 4 is positive and on the x axis so you go right. -7 is negative and on the y axis so you go down

Busy intersection There is a busy intersection between two one-way streets: Main Street and 1st Avenue. Cars passing through the intersection can only pass through one at a time. When multiple cars arrive at the intersection at the same time, two queues can build up - one for each street. Cars are added to the queue in the order at which they arrive. Unfortunately, there is no traffic light to help control traffic when multiple cars arrive at the same time. So, the local residents have devised their own system for determining which car has priority to pass through the intersection: - If in the previous second, no car passed through the intersection, then the first car in the queue for 1 st Avenue goes first. - If in the previous second, a car passed through the intersection on 1st Avenue, then the first car in the queue for1stAvenue goes first. - If in the previous second, a car passed through the intersection on Main Street, then the first car in the queue for Main Street goest first.
