A) In 3 weeks, Amy will have $121.

B) An equation that shows the amount of savings Amy will have in x number of weeks is 100 + 7x.

C) Becky is the first person to save $200 in 11.5 weeks.

An equation is a mathematical statement that two or more mathematical expressions share equality in their values.

Equations depict the fact that two or more expressions have the same or equivalent values using the equation symbol (=).

The total amount of savings required for a new phone = $200

Amy's savings in x weeks = 100 + 7x

Becky's savings in x weeks = 85 + 10x

Caroline's savings in x weeks = 94 + 8x

Dan's savings in x weeks = 110 + 7x

Amy's savings in 3 weeks = $121 ($100 + 7(3)

If 100 + 7x = 200

7x = 100

x = 14.3

= 14.3 weeks

If 85 + 10x = 200

10x = 115

x = 11.5

= 11.5 weeks

If 94 + 8x = 200

8x = 106

x = 13.25

= 13.25 weeks

If 110 + 7x = 200

7x = 90

x = 12.86

The percentage increase in price from April to June to Mrs Ezeaku, based on the cost of the bag is 66.7%

First, find the price of a bag in June. If 3/5 of a bag costs N2,400, then a full bag would be:

= Cost of proportion / Proportion of bag

= 2, 400 / (3 / 5)

= N4, 000

The percentage increase from April to June is:

= ( Price in June - Price in April) / Price in April x 100%

= ( 4, 000 - 2, 400) / 2, 400 x 100%
= 1, 600 / 2, 400 x 100%

= 66.7%

Let x represent the amount of milligrams required for a person who weighs 140 lb.

We were told that the dosage of a cold medication is 2 mg for every 80 lb of body weight. The equations would be set up as shown below

2 = 80

x = 140

By crossmultiplying, we have

x * 80 = 2 * 140

80x = 280

We would divide both sides of th equation by 80. We have

80x/80 = 280/80

x = 3.5

Therefore, 3.5 milligrams of this medication are required for a person who weighs 140 lb

The midpoint of two points is given as

(x1 + x2)/2, (y1 + y2)/2

Given that the coordinates of the midpoint are (5, -1), let the coordinates of point B be x2 and y2

(2 + x2)/2 = 5

2 + x2 = 10

x2 = 10 - 2

x2 = 8

(-6 + y2)/2 = -1

-6 + y2 = -2

y2 = -2 + 6

y2 = 4

The coordinates of B are (8,4)

If the initial fee is $20 and additionally $15 is charged per day, then the total amount is given by:

Where "x" is the number of days and "A" the total amount to pay. Since the total amount is less than $110, then we have the following inequality:

This is the inequality that can be used to determine the value of "x".

The reason for the statements for the algebraic proof is as follows;

The equation given is as follows:

3x / 6 = 4 . This equation is given.

Therefore,

3x / 6 = 4

Using multiplication property of equality, we will multiply both sides of the equation by 6.

3x / 6 × 6 = 4 × 6

3x = 24

The multiplication property of equality states that when we multiply both sides of an equation by the same number, the two sides remain equal.

Hence,

3x = 24

Using division property of equality, we divide both sides by 3.

3x / 3 = 24 / 3

x = 8

The Division Property of equality says that dividing both sides of an equation by the same number does not affect the equation.

Answer:

25th percentile: 5

60th percentile: 12

Explanation:

To find the percentile, we need to organize the data from lowest to greatest, so

1 3 4 4 5 6 6 7 8 8 9 12 14 15 17 17 19 20 20 20

Therefore, there are 20 values in the data set.

The position of the 25th percentile can be calculated as:

Then, the position of the 25th percentile is 5th. In this case, the number in this position is 5 so the 25th percentile is 5

In the same way, we can calculate the position for the 60th percentile as follows:

Then, the position of the 60th percentile is the 12th. In this case, this value is 12, so the 60th percentile is 12.

So, the answers are:

25th percentile: 5

60th percentile: 12

7:6

Step-by-step explanation:

add the amount of lemonade and soda together, that is 42.

so you have 42:36.

you need to simplify it, so you divide 42 / 2 = 21

then you divide 36 / 2 = 18.

so now you have 21:18.

then you divide 21 / 3 = 7

then you divide 18 / 3 = 6.

so therefore, your answer is 7:6.

Answer:

In order from left to right: Apple, Mango, Grapes, Kiwi, Banana

Step-by-step explanation:

The one furthest left is the only one that goes above 50, so it has to be apple at 55. The one next to it falls between 20 and 30, so it is going to be Mango at 25. The one next to it lies between 30 and 40, so it will be Grapes at 35. The next one falls exactly at 10, so it is Kiwi. And finally, the only one left is Banana, which is good because the bar sits at 50.

The objective is to determine whether the median of a data set is same or not while ordering from greatest to least or least to greatest.

There are two possible data sets, which is even number of sets or odd number of sets.

If the number of sets (n) is even, consider two terms,

Then, the average of these two numbers will gives the median of the even sets.

If the number of sets (n) is odd, the median can be calculated as,

Tori, this is the solution to the exercise:

Step 1: Let's remember that this is a case that we can solve using the following equation form:

y = mx+b, where m is the slope and b is the y-intercept.

Step 2: Solving for b:

y = mx + b

We replace x and y with the coordinates:

1 = 3 * 2 + b

1 = 6 + b

b = 1 - 6

b = - 5

Step 3: Therefore, the equation of the line that passes through the point (2,1) with a slope of 3 is:

The mean length (rounded to 2 DP) of these 15 people's index finger is 12.15 cm.

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

It is given that:

The mean length of 4 children's index fingers is 8.7cm.

The mean length of 11 adults' index fingers is 13.4cm.

The mean of 15 people = [8.7x4 + 13.4x11]/15

By writing and solving a system of equations, we will see that the club sold 32 oranges and 68 bars.

Here the solution will be the number of oranges and protein bars sold.

Let's define:

x = number of oranges.

y = number of bars.

We know that they sell 100 items and win a total of $304, then we can write the system of equations:

x + y = 100

x*$1 + y*$4 = $304

Isolating x on the first equation we get:

x = 100 - y

Replacing that in the other equation we get:

(100 - y)*$1 + y*$4 = $304

$100 - y*$1 + y*$4 = $304

y*$3 = $304 - $100 = $204

y = $204/$3 = 68

y = 68

And the value of x is:

x = 100 - y = 100 - 68

x = 32

That is the solution, x = 32 and y = 68.
