In step 3 the student first made an **error **to add a term 4.

**Linear equation **of two **variables **is an **equation **where the **highest degree **is 1 and the number of **variables **is 2.

for example: 2x+2y=9

Here, the given two **equations **are

Equation 1: m = 8 + 2n

Equation 2: 4m = 4 + 4n

To solve these **equation **multiply -4 on both sides in **equation **1

Step 1:

**Equation **-1*4 : −4(m) = −4(8 + 2n)

**Equation **-2: 4m = 4 + 4n

Step 2:

**Equation **-1*4 : −4m = −32 − 8n

**Equation **-2: 4m = 4 + 4n

Then add these two **equations **to eleminate the m terms.

Step 3:

**Equation **-1*4 + **Equation **-2 : −4m + 4m = −32 − 8n +4+ 4n

In the question term **4 **is missing to add in right hand side in step 3

Step-4: 0=-4n-28

taking **variable **term on one side and **constant **term on one side and then dividing the **coefficient **of the **variable **on both sides.

Step-5: n=-7

Therefore in step 3 the student first made an **error **to add a term 4.

The error can be found in **step 3**. The student forgot to add four which caused him to mess up on the rest of the steps.

Question

Mrs.Klein uses 12 cucumbers to make 3 jars of pickles. At this rate, how many cucumbers will she need to make 10 jars of pickles?

Solution 1

The answer to this question is 40 cucumbers

Solution 2

**Answer:**

40

**Step-by-step explanation:**

So she has 12 cucumbers to make 3 jars of pickles.

She uses 4 cucumbers to make each jar. (Based on the equation 12➗3 =4)

Shawtyyyy better be using those pickles on burgers and not eating it raw.

So she has 10 jars right? Right, and you know she used 4 pickles per jar, so

we can get the answer by the equation of 10 x 4 = 40

Have a great day shawtayyyyyy!

Question

What is 4.1363636... as a fraction?

Solution 1

**Answer:**

**x = .**

**Step-by-step explanation:**

Given : 4.1363636...

To find : Write as fraction .

Solution : We have given that

Let x = 4.1363636...

We can see number 36 ( 2 digit repeating ) so we will multiply it by 100

On multiplying both sides by 100

**100x = 100 * 4.1363636...**

100 x = 413 .63636 .....

We can write it in term of x

100 x = x + 409 .5

On subtracting both sides by x

100 - x = 409 .5

99 x = 409 .5

On dividing both sides by 99

x = .

x = .

x = .

On dividing both number by 9

x = .

**Therefore, x = .**

Solution 2

We have that the the Representation of** 4.1363636** as** fraction** is

From the question we are told that:

4.1363636. is in **decimal form**

**Fraction**

This is the representation of a **number** in the format of a **numerator **and a **denominator**

Generally, the Representation of** 4.1363636** as **fraction ** is mathematically given by

Having defined** fractions** we have that

Therefore

The **4.1363636** as fraction is mathematically given by

in conclusion

The the Representation of** 4.1363636** as **fraction** is

Solution 1

50 mg, 500 g . 5,000 mg

Question

A school table has 8 sides of equal lengths. if one side is 4 feet, what is the perimeter of the table?

Solution 1

Since the table has 8 sides that all have the same length then multiply 4 by 8 so the answer is 32

Solution 2

One side = 4 feet

4 x 8= 32

Eight sides = 32 feet

4 x 8= 32

Eight sides = 32 feet

Question

If 75 capsules of a drug cost $60, what would 40 capsules of the same drug cost?

Solution 1

75 capsules = $60

1 capsule = 60 ÷ 75 = $0.80

40 capsules = $0.80 x 40 = $32

**Answer: $32**

1 capsule = 60 ÷ 75 = $0.80

40 capsules = $0.80 x 40 = $32

Solution 2

You’re getting riped of for that price

Question

The mean for your data set is 13. The standard deviation is 2.5. What is the z-score for 10? Note 1: If necessary, round your answer to 3 decimal places

Solution 1

Z-score is given by the formula:

z=(x-μ)/σ

where:

μ-mean

σ-standard deviation

thus the z-score for the data set with mean 13 and standard deviation of 2.5 will be:

z=(10-13)/2.5

z=-1.2

z=(x-μ)/σ

where:

μ-mean

σ-standard deviation

thus the z-score for the data set with mean 13 and standard deviation of 2.5 will be:

z=(10-13)/2.5

z=-1.2

Question

Two quantities are related as shown in the table below: x. y
2. 3
4. 4
6. 5
8. 6
Which equation best represents the relationship?

Solution 1

First you need to find the slope and in order to do that you need to use the following equation:

y-y

——

x-x

The y with the greatest value goes first and then the lowest. Same thing with x.

Choose two coordinates from the table

Ex: (4,4) & (2,3)

4-3=1

——-

4-2=2

The slop is 1/2 or 0.5

There is a y intercept which is 2. You get 2 when you divide 1 by 2

So the equation would be

y=1/2x+2 or y=0.5x+2

Hope this helped
