Help out please and thank you

Answer:

Option (iv) is correct.

Step-by-step explanation:

The linear equation is the equation in which the degree of the equation is 1.

(i) x/3 = 12

As the degree of equation is 1, so, it is a linear equation.

(ii) x + 1 = 6

As the degree of equation is 1, so, it is a linear equation.

(iii) x + y + z = 17

As the degree of equation is 1, so, it is a linear equation.

(iv) x y + x / y = 3

x y^2 + x = 3 y

The degree of equation is 3, so the equation is non linear.

Answer:

Simple random sampling

Step-by-step explanation:

Luke wants to study average minutes students read each night. For that matter, he has selected a 'sample' of 25 students from entire 'population' of students in school.

He has selected the sample students randomly, for collecting data related to minutes of study each night. He also collects data from them directly ie with primary contact with them.

So, primary data collection, simple random sampling - has been used as a type of data collection.

1.) Multiply Denominator:

9x3= 27

27 will be your new denominator for your answer.

then take 5 and multiply by 3.

5x3=15

then take 1 and multiply by 9.

1x9=9

Afterwards, you plus 15 and 9 to get 24.

so your fraction for the end will be 24/27.

Answer:

1/4 and 1/12

Step-by-step explanation:

We know that

1 foot = 12 inches

therefore, 1 inch = 1/12 foot

hence, 3 inches  = 3/12 foot

= 1/4.

Therefore, the required fraction is = 1/4

Similarly,

1 yard = 36 inches

This implies 1 inch = 1/36 yard

Hence, 3 inches = 3/36 = 1/12

Therefore, the required fraction  = 1/12

Answer:

[tex]90\% = \frac{90}{100} \\ = \frac{9}{10} = 0.9[/tex]

Answer:

The simplest form of

90/100

is

9/10

Step-by-step explanation:

Find the GCD (or HCF) of numerator and denominator

GCD of 90 and 100 is 10

Divide both the numerator and denominator by the GCD

90 ÷ 10

100 ÷ 10

Reduced fraction:

9

10

Therefore, 90/100 simplified to lowest terms is 9/10.

Mean=23

Median=21.5 its a hard one to do so yeah

Modes=28

Range=22

Answer:

(5x + 16) + 102 + 92 + 100 = 360

(5x + 16) + 294  = 360

-294                   -294

5x + 16 = 66

-16           -16

5x = 50

Divide by 5 on both sides.

x = 10 degrees

A quadrilateral will always equal 360 degrees

A triangle will always equal 180 degrees.

Answer:

y=-1/2x-1

Step-by-step explanation:

Answer:

77.5°

Step-by-step explanation:

Recall that the sum of angles in a triangle is 180 degrees.

Given the triangle MNP with the measure of angle NPM is 80° and the measure of angle MNP is 22.5°

Then

angles NPM +  MNP + PMN  = 180 degrees

This means that

80 + 22.5 + PMN = 180

102.5 + PMN = 180

Collect like terms

PMN  = 180 - 102.5

= 77.5°.

Answer:

2 yards 5 inches will be equivalent to 77 inches

Step-by-step explanation:

Given length -

2 yards 5 inches

One yard has 36 inches

Two yards will have 2*36 = 72 inches

Thus, 2 yards 5 inches will sum up to 72 inches + 5 inches = 77 inches

Hence,  2 yards 5 inches will be equivalent to 77 inches

Answer:

3 yards = 9 feet

77 inches = 2 yards 5 inches

48 inches = 1 yard 1 foot

32 inches = 2 feet 8 inches

Answer:

Missing term = 6x

Step-by-step explanation:

We got:

=> 4x by multiplying +4 and x (x * 4 = 4x)

=> 12 by multiplying +4 and +3 (4 * 3 = 12)

=> 2x² by multiplying 2x and x (2x * x = 2x²)

Similarly we will get the "missing term" by multiplying 2x and +3

=> Missing term = 6x, (2x * 3 = 6x)

Hope this helps!

Answer:

12x + 18y + 6z + 4x - 4z

Step-by-step explanation:

Given the expression : 3(4x + 6y + 2z) + 4(x – z)

To eliminate the parenthesis ; we use the distributive property :

3(4x + 6y + 2z) + 4(x – z) becomes ;

3*4x + 3*6y + 3*2z + 4*x + 4*-z

12x + 18y + 6z + 4x - 4z

Hence,

12x + 4x + 18y + 6z - 4z

16x + 18y + 2z

Answer:

f(5) = 30  so x=5

Step-by-step explanation:

We want to find the value of x which makes the y value of the function 30

Looking at the graph x=5 makes y=30

Answer:

x = 80.96

Step-by-step explanation:

9x * 3x +1 = 2187

27x +1 = 2187

27x = 2187-1

27x = 2186

x = 2186/27 = 80.96(2dp)
