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

Fernando spent $20 of his $50 weekly allowance on snacks. What percent of his weekly allowance did he spend snacks?

Answers

Answer:

is the answer of 50 and spend 20 you have 30 left

Answer:

40%

Step-by-step explanation:

A good way to remember how to do percentages is starting with 10% of overall.

Overall, 10% of the $50 would be $5
you just move the decimal from $50.00 to $5.00
moving it to the left once, for ten percent

theres $20 so thats the 10x2

20 goes into 100, 5 times ...

It just so happens in this scenario, its 20% just like the $20 ... doesnt always happen like this.

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.

The constant of Proportionality is 8.

What is constant of Proportionality?

If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.

Given:

Total Baseball Caps= 30

Total amount of Cap= $240

let the number of caps sold be c.

Then, the equation is

30 c= 240

and, c= 240/30

c= 8

Hence, the constant of Proportionality is 8.

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

Joseph was kayaking on the Hudson River. While looking at the Breakneck Ridge trail-head, he lost a whole bag of donuts. Joseph didn't realize he had lost it for fifteen minutes. That's when he turned back and started going in the opposite direction.

Answers

Answer:

8 miles per hour

Step-by-step explanation:

Actually pretty simple. It took 15 minutes for the bag to travel two miles from the Breakneck Ridge so it will be four miles per 30 minutes six miles per 45 minutes and 8 miles per hour.

= 2

Distance between points (-1.5, 1.25) and (-1.5, -0.75) is 2

The vertical distance between the points A and B are D = 2 units

What is the distance between two points?

Let the two points be A ( x₁ , y₁ ) and B ( x₂ , y₂ )

The distance from A to B is the same as the distance from B to A

Distance between two points is the length of the line segment that connects the two points in a plane.

The formula to find the distance between the two points is usually given by D = √( ( x₂ – x₁ )² + ( y₂ – y₁ )²)

This formula is used to find the distance between any two points on a coordinate plane or x-y plane

Given data ,

Let the distance between 2 points be represented as D

Now , let the first point be A ( -1.5 , 1.25 )

Let the second point be B ( -1.5 , -0.75 )

The distance D = √( ( x₂ – x₁ )² + ( y₂ – y₁ )²)

And , the vertical distance between A and B = |y-coordinate of A - y-coordinate of B|

So , the value of D = |1.25 - (-0.75)|

D = 2 units

Hence , the vertical distance is D = 2 units
