if there is 16 boys in the classroom are 40% of the class, how many students are there in the class

Answers

Answer 1

Answer:

40 students

Step-by-step explanation:

16 = 40%

Divide by two to get 20% = 8

Then multiply by 5 to get 40 = 100%

There’s other ways to do this, BUT this is the way that I solve it.

Answer 2
16=40% 60% left 60%- 40%=20% there are 30 people in the class

Answer:

3

is the answer

Step-by-step explanation:

The answer is 2.

1 1/2, 1 1/2, 2, 2, 2, 2 1/2, 3, 3 1/2, 4

Cross each side out until you get to the middle, in this case it’s 2 and 2.

Add the two numbers up and divide by two, which equals 2.

Which of the following lists is in order from smallest to largest? 1.4, 1/4 ,14% 1/4 , 14%, 1.4 14%, 1/4 , 1.4 1.4, 14%, 1/4

Answers

Firstly, I noticed that there are fractions, decimals, and percents. I will change everything to percents, so it’s more easy for me to compare each of them.

List 1. 140%, 25%, 14%. This is from greatest to least, not least to greatest.
List 2. 25%, 14%, 14%. This is not from least to greatest, either.
List 3. 14%, 25%, 140%. This is from least to greatest.
List 4. 140%, 14%, 25%. This is not from least to greatest.

List 3 is from least to greatest. I got this answer by converting all of the fractions and decimals to percentages.

Joe and Marty work for two different landscaping companies. Joe earns a base amount of $15 and $8 per lawn. Marty earns a base amount of $45 and $6 per lawn. Last week, they earned the same amount of money. How many lawns did they each mow?

Answers

Answer:

I belive Joe mowed 51 lawns and Marty mowed 23.

Step-by-step explanation:

Joe and Marty each mowed a total number of 15 lawns last week and they earned the same amount of money.

What is a linear equation?

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as the linear equation in one variable.

Joe earns a base amount of $15 and $8 per lawn.

Marty earns a base amount of $45 and $6 per lawn.

Let's suppose they both mow x number of lawns.

Then Joe's total income is given by:

$(15+8x)

And Marty's total income is given by:

$(45+6x)

As they earned the same amount of money, mathematically:

(15+8x) = (45+6x)

15 + 8x - 6x = 45 +6x - 6x   (subtract by 6x on both sides)

15 + 2x -15 = 45 -15              (subtract by 15 on both sides)

2x = 30

x = 15    (divide by 2 on both sides)

If we put x = 15 in Joe's total income expression, we get:

15+8×15 ⇒135

If we put x = 15 in Marty's total income expression, we get:

45+6×15 ⇒135

Thus, Joe and Marty each mowed a total number of 15 lawns last week and they earned the same amount of money.

We know that an exterior angle is supplementary to interior angle. remember that the exterior angle is equal to the sum of the two opposite interior angles. Suppose that the measure of exterior angle is x + 72° and the measure of two interior angles are 34° with the right angle of 90°. We use (x = a + b) formula. Hence, we have the value of x = 52°. Thats all.

Drag justifications into the table to explain each step in solving the equation 5(2x+1)=2(4x-7)+3

Answers

x= -8 (Answered)
10x+5=14x-14+3

The justifications are in the order distributive property, associative property of addition, Combine like terms, Addition property of equality and multiply by LCD.

What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given equation is,

5(2x + 1) = 2 (4x - 7) + 3

Using distributive property, a(b + c) = ab + ac

10x + 5 = 8x - 14 + 3

10x + 5 = 8x - 11  [associative property of addition]

10x - 8x + 5 = -11

2x + 5 = -11  [Combine like terms]

2x + 5 - 5 = -11 - 5

2x = -16 [ Addition property of equality]

2x / 2 = -16/2

x = -8  [multiply by LCD]

Hence the justifications are done.
