For Emily’s birthday, her father treated her and five friends to a dinner at a restaurant at the mall. Emily and her friends ordered three pizza dinners at $6.25 each and three chicken baskets at $7.50 each. All six people ordered soft drinks costing $1.25 each. The sales tax on the meal was 4.5%, and the tip was 15%. What was the total cost of the meal, including the sales tax and the tip?

Answers

Answer 1
6.25 times 3 is 18.75
7.50 times 3 is 22.5
1.25 times 6 is 7.5
Add those and you get 48.75.
48.75 times .045 is 2.19
48.75 times .15 is 7.31.
Add the tax and tip to the value, you get $58.25.
Answer 2

Answer:

$58.58

Step-by-step explanation:

the meal was $48.75

the tax was 4.5%

Multiply 48.75 by 4.5 as a decimal to do this divide 4.5 by 100 = 0.045

48.75 x 0.045 = 2.19375 round to the nearest hundreth = 2.19

48.75 + 2.19 = 50.94

tip on tax = 58.58

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Harrison has 70 CDs in his music collection. If 10% of the CDs are country music and 60% are pop music.

The percentage of the other CDs will be:-

P = 100 - 60 - 10

P = 30%

The number of the other CDs will be:-

Number = 70 x 30%

Number = 70 x ( 30 / 100 )

Number = 21

I would like to ask anyone if they would mind helping me if they could explain in a way that makes sense, how to find the y-intercept with two points... please help me, google tells me how but my head hurts and it makes no sense TwT ty in advance!!

Answers

Answer:

Ok so the two points that are given need to be in the form of y2-y1 over x2-x1, meaning the x value from the second set of points needs to be subtracted from the x value from the first set of points, and it is the same for the y values. Then that gives you the slope. You add the slope to the equation y=mx+b. The slope is m, so you put the slope in the m spot. If the slope were 3, it would look like y=3x+b because it is in the m spot. Then, you can choose any 1 set of points given and plug it into the equation. I am going to use the slope 3 , like the last example, and plug it in with the set of points. Say the point was (5,2), you will plug the x value, which is 10 in the situation, next to the the slope. The slope will then be 3(5). Then you will plug in the y value, which is 2, into the y place. At the end, the equation will look like this: 2=3(5)+b. Then you multiply 3 and 5, which is 15, and subtract 2 and 15 which will give you -13. The answer will then be -13=b. That is the y-intercept.

Step-by-step explanation:

hey! if you have the equation, for example:

y=3x+4

the y-intercept would be 4! this is an easy hack to use if you already have the equation. in an equation, the number on the very end will always be your y-intercept if it is correctly written in slope intercept form.

if you do not have the equation but have the points, the y-intercept would be the point on the line that touches the y-axis first.

for example:

the line crosses through the 3rd line on the y axis. your y-intercept would be 3. it is the point in which your line crosses on the y-axis line that goes up and down the middle of the graph.

Y=2/3x-2
That’s what I got if it’s wrong I’m sorry haven’t done this kind of work in 1 maybe 2 years

Answer:

-3

Step-by-step explanation:

The x-intercept is 3, here's why

First, you need to get the slope

y2-y1

--------

x2-x1

You should get 2/3

Next, you need to use y=mx+b

y= 2/3x+b

2= 2/3(6)+b       You get 6 and 2 from the coordinates

Once this is worked out you'll get y=2/3x-2

To get the x intercept you need to set y equal to 0

0=2/3x-2

Add 2 to each side

0-2 = 2/3x

Multiply each side by 3/2 to isolate x

-2 *3/2 = 2/3x * 3/2

-3 =x

The x intercept is -3

Answer:

The answers below are all right :D

Step-by-step explanation:

My answer: Both are correct because to find the equation u need both the pointslope form and slope intercept form.

Short Answer: Both Samuel and Helena are correct.  Both forms result in the same equation.  Slope-intercept uses slope and a point to find the y-intercept.  Point-slope uses slope and a point to solve for y to form the equation.

Sample Response: Both are correct. Using either form will result in the same equation. The slope-intercept form uses slope and a point to find the y-intercept. Point-slope form uses the slope and a point to solve for y to generate the equation.
