B: 2 1/3 > 2 1/6

is the correct answer

A,C, and D are false answers and are incorrect

Answer:

2 1/3 > 2 1/6

Step-by-step explanation:

5/6 < - 1/3

2 < -2 1/2

negative cannot be bigger than positive

1 1/4 > 1 1/3 if you divide them you would get 1.25 > 1.333333, so 1 1/4 not bigger than 1 1/4

Answers

Answer:

A. -2, x= -2

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Given

- 12x - 2(x + 9) = 5(x + 4) ← distribute parenthesis on both sides )

- 12x - 2x - 18 = 5x + 20 , that is

- 14x - 18 = 5x + 20 ( subtract 5x from both sides )

- 19x - 18 = 20 ( add 18 to both sides )

- 19x = 38 ( divide both sides by - 19 )

x = - 2 → A

A class has 50 students. 20 students are playing basketball and rest are playing volleyball. The percent of the class playing basketball is?
a) 20 percent
b) 40 percent
c) 60 percent ​

Answers

Answer:

60 percent

Step-by-step explanation:

so 50 is half of 100,right? so that means you can just multiply everything by 2 to make it easier. so then there are 100 students and 40 play basket ball. so that means 40 percent play basketball and that only leaves 60 remaining :)

60% should be right because it’s out of 100 and 100 - 20 is 60

Choose the correct equation to represent the number line model.

Answers

Answer:

-5 + -4 = -9

Step-by-step explanation:

-5 + -4 = -9

Start at 0.

You will need to move 5 spaces to the left (Negative numbers move to the left while positives go right).

And -4. Move 4 spaces left again. There you land at -9.

The plus sign is just to combine -5 and -4 together.

Thus the answer is:

-5 + -4 is -9.

Here’s why the other equations aren’t correct.

The first equation says “5 + 4 = 9”.

To represent this, you would move 5 spaces to the right (because the number is posititve.)

Then combine 4. Which you move 4 spaces to the right again. This leaves you at 9 instead of -9.

The second equation says “-5 + -9 = -14”.

To represent this, you would move 5 spaces to the left.

Then move 9 spaces to the left again. Which leaves you at -14.

Your final destination should be -9. Not anywhere else.

4. Find the width of a rectangle if the perimeter is
14.00 inches and the length is 3.6 inches.

Answers

Answer:

The width of the rectangle is 3.4 inches

Step-by-step explanation:

3.6 inches = length  LxW=Area

W= width

Perimeter= 2x(Length)+2x(Width) 2x3.6=7.2

7.2+2(W)=14.00 subtract 7.2 on both sides 14.00-7.2=6.8

2(Width)=6.8 divide both sides by 2 6.8/2=3.4

So width of rectangle is 3.4

A class has 30 boys and 20 girls. The average age of
boys is 11 yrs and girls 12 What is the
average age of the whole class."
​

Answers

x = total age of boys

x / 30 = 11yrs

Multiply both sides by 30

x = 330

y = total age of girls

y / 20 = 12

Multiply both sides by 20

y = 240

(240 + 330) / 50 = 11.4 yrs

The average age of the whole class = 11.4 years.

Given:

A class has 30 boys and 20 girls.

The average age of boys and girls is 11 and 12 respectively.

To Find:

The average age of the whole class.

Solution:

Boys = No. of boys × Age

Boys = 30 × 11 = 330

Girls = No. of girls × Age

Girls = 20 × 12 = 240

Average Age = Boys + Girls / Total no. of boys and girls

Average Age = 330 + 240 / 50

Average Age = 570 / 50

Average Age = 11.4

Answer:

Average age of of the whole class is 11.4 .

Given ABCE is a rectangle, find the length of AD

Help me

Answers

Answer:

AD = 10

Step-by-step explanation:

It's given that ABCE is a rectangle.

Therefore, measure of opposite sides of the rectangle will be equal.

AB = EC

AB = ED + DC

12 = ED + 4

ED = 8

Measure of side AE = 6

Since, measure of interior angles of a rectangle = 90°

Therefore, ΔEAD will be a right triangle.

By Pythagoras theorem,

AD² = AE² + ED²

      = 6² + 8²

AD = [tex]\sqrt{36+64}[/tex]

      = [tex]\sqrt{100}[/tex]

      = 10

Therefore, measure of side AD = 10 units
