You have to find x then add 13

Question

The product of two numbers is 24 negative if one of the factor is -6 what is the other factors

Solution 1

The other factor is 4 because if you multiply a negative with a positive, you'll get a negative. -6 * 4 will give you - 24.

Question

Find the product of two numbers whose sum is 11 and difference is 3.

Solution 1

The **two numbers** are **7 **and **4**

Let the first number = x

let the second number = y

The sum of the numbers is 11, in algebra form x + y Â = 11

The difference of the two numbers is 3, in algebra form, x - y = 3

To obtain the two **unknown numbers**, we solve the two equations;

from the first equation, x = 11 - y

substitute the value of x into the last equation;

(11 - y) - y = 3

11 - y - y = 3

11 - 2y = 3

2y = 11 - 3

2y = 8

y = 4

The value of x = 11 - 4 = 7

Thus, the **two numbers** are **7 **and **4**

Solution 2

All you would do is minus what you have, like 11-3= 8 which would be 8+3=11 and 11-8=3 which means now you have the sum of 11 and the difference of 3.

Question

Runyon Company sells T-shirts ($5) and shorts ($6). If total sales were $1,040 and people bought 4 times as many T-shirts as shorts, what was the total number of T-shirts and shorts sold

Solution 1

You answer would beÂ **4,160 **and you get the answer by multiplying 1,040 and 4 and you get **4,160**

Question

during a flu epidemic,146 students out of 680 who attend Lincoln middle school were absent. what percent were absent?

Solution 1

21% were absent, if you divide 146 by 680 and multiply by 100, then round to the nearest whole number, you get 21

Question

Lara solved an equation incorrectly, as shown below: Step 1: 2x = 18
Step 2: x = 18 âˆ’ 2
Step 3: x = 16
Which statement best explains why Step 2 is incorrect in Lara's solution?
A) She did not divide 18 by 2.
B)She did not add 2 to 18.
C)She did not multiply 18 by 2.
D) She did not multiply 18 two times.

Solution 1

We have been given the steps to solve the equation as

Step 1: 2x = 18

Step 2: x = 18 âˆ’ 2

Step 3: x = 16

There is an error in step 2.

We have

x is in multiplication with 2. So in order to get rid of 2 from the left hand side, we perform opposite operation of multiplication i.e. division.

So we must divide both sides by 2.

**Therefore, A is the correct option.**

**A) She did not divide 18 by 2.**

Solution 2

The answer is b. 18/2=9

Question

What number is 21% of 450

Solution 1

Since percent means per hundred, you are basically asking how many is 21 per hundred of 450.

To calculate 21 of 450, we solve the the problem by using the following formula: (X*Y)/100 where X=21 and Y=450.

Thus, when we enter 21 and 450 into our formula, we get this:

(21*450)/100 = answer

First we multiplied 21 by 450 and then we divided that by 100. When we did this, we found the answer to be 94.5.

Therefore, 21 percent of 450 is 94.5.

Therefore, 21 percent of 450 is 94.5.

Solution 2

The answer would be 94.5

21% of 450 is 94.5

21% of 450 is 94.5

Question

PLEASE HELP !Barry has an ice tray that makes ice cubes shaped like a cone with a diameter of 2 cm and height of 2 cm. To the nearest cubic centimeter, what is the volume of an ice cube from Barry's tray? 2 cmÂ³ 8 â€‹cmÂ³â€‹ â€‹ â€‹ 25 â€‹cmÂ³â€‹ â€‹ â€‹ 101 â€‹cmÂ³â€‹ â€‹ â€‹

Solution 1

To the nearest cubic centimeter, the volume of an ice cube would be 2 cmÂ³. The formula for a cone isÂ Ï€rÂ²(h/3), and when you divide the diameter by 2, you get one, so the formula would turn intoÂ Ï€1Â²(2/3), giving you the answer.

Question

This table shows the size, in acres, of four large water parks. What is the median of the sizes of the four water parks? 60 acres 63 acres 64 acres 65 acres Park Size (in Acres) A 66 B 70 C 60 D 60

Solution 1

The median of this list of numbers is 63.5 acres (not given).

The median of a set of data is the middle value. If you order the 4 numbers you have:

60Â 63Â 64Â 65

The middle is in between 63 and 64, therefore the median is 63.5.

Question

Ming wrote the table of points below. x y 5 10 10 20 15 30 Which explains whether or not Ming has described a proportional relationship, and why? Ming has described a proportional relationship because the ordered pairs are linear and the line passes through the origin. Ming has not described a proportional relationship. Although it is a linear relationship, it does not pass through the origin. Ming has not described a proportional relationship. Although it passes through the origin, it is not a linear relationship. Ming has described a proportional relationship because the line does not pass through the origin.

Solution 1

**Answer:**

Option A.

**Step-by-step explanation:**

The given table is

x Â Â Â y

5 Â Â 10

10 Â Â 20

15 Â Â 30

From the given table it is clear that the value of y increases by 10 when the value of x increases by 5. It means the rate of change is constant.

So, the given table represents a linear relationship.

If a linear function passes through the two points then the equation of line is

The linear function passes through (5,10) and (10,20), so the equation of line is

For x=0,

It means it passes through the origin, i.e., (0,0).

Ming has described a proportional relationship because the ordered pairs are linear and the line passes through the origin.

**Therefore, the correct option is A.**

Solution 2

This is a proportional relationship.

If you drew the points and made a line, it would pass through the origin. Also, all you need to do is multiply the x value by 2 and you have the y-value.

If you drew the points and made a line, it would pass through the origin. Also, all you need to do is multiply the x value by 2 and you have the y-value.

Question

What is the total cost of $ 2.95 notebook plus 5 %

Solution 1

First, you convert 5% to decimal. For your info, percents are always equal to 100. So, you divide 5 by a 100, which gives you 0.05. Then, you multiply 2.95 by 0.05. 2.95 x 0.05 is 0.1475 which is about 0.15. Then, you add 0.15 to 2.95. The total cost of a $2.95 notebook plus 5% is aboutÂ $3.10.
