3 x 7/10 = ?

What is the ?


A. 10/21

B. 24/10

C. 21/13

D. 21/10

Answer: See explanation

Step-by-step explanation:

1. Step 1: Add up all the numbers.

12 + 15 + 10 + 15 + 11 + 12 + 15 = 90

Step 2: Count how many numbers there are.

There are 7 numbers

Step 3: Divide the sum of the numbers by amount of numbers.

90 ÷ 7 = 12.85

12.85 ≈ 12.9

Mean = 12.9 in tenth place or 13 in whole place

2. The mode is the number that appears the most

15 appears 3 times.

3. 38 / +38

4. 1 week = 7 days

7 × 2 = 14

9 weeks = 9 × 7 = 63

63 × 3 = 189

189 + 14 = 203

203 miles in all

5. Area of 1st rectangle: b × h

4 × 14 = 56

Area of 2nd rectangle: b × h

4 × 14 = 56

56 + 56 = 112

Area of polygon = 112

Answer:

top right

Step-by-step explanation:

Answer:

The answer would be B!

Step-by-step explanation:

To find which expression is equivalent, do the distributive property.

A. 1/5 * 4x = 4/5x

    1/5 * 1/1 = 1/5

4/5x + 1/5  <--- This is wrong!

B.  2/5 * 2x = 4/5x

    2/5 * 3/1 = 6/5 = 1 1/5

4/5x + 1 1/5 <--- This is correct!

C. 4/5 * x = 4/5x

    4/5 * 2/1 = 8/5

4/5x + 8/5 <--- This is wrong!

D. 5/4*x = 5/4x

    5/4 * 1/1 = 5/4

5/4x + 5/4 <--- This is wrong!

Therefore, the answer is B!  Hope this helps!

Answer:

N= -5/8=0.625

Step-by-step explanation:

2.1      Solve  :    -8n-5 = 0  

Add  5  to both sides of the equation :  

                     -8n = 5

Multiply both sides of the equation by (-1) :  8n = -5

Divide both sides of the equation by 8:

                    n = -5/8 = -0.625

Answer:

4 feet

Step-by-step explanation:

The height of the tower when she will finish is 4 feet.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Priya is stacking building blocks to make a tower. She takes a break when the tower is 2¹/₂ feet tall, which is 5/8 of the height of the tower she wants to build.

The height of the tower will be calculated as,

5 / 8 x = 2¹/₂

x = ( 8 / 5 ) x 2.5

x = 4 ft

Answer:

73

Step-by-step explanation:

7^2 = 49

Order of operations, parenthesis first.

3*4 = 12

5*12 = 60

49+60 = 109

6^2 = 36

109-36 = 73

Answer:

1.) 73

2.) x+x+x+y+y = 2y + 3x

2(x+2y) = 2x + 4y

Answer:

= -6

positive/negative= negative (the sign rule)

54/9=6

You can use the calculator too

Step-by-step explanation:

Answer:

First box is 6

Second box is 48

Third box is 1

Step-by-step explanation:

We have a multiplication problem with 3 boxes and are asked to figure them out.

Let's start with the first box, we can see that after the = sign, there is 48 as the denominator.

What times 8 equals 48?

6.

Therefore 6 is in the first box.

Now for the second box, when multiplying fractions, we multiply across, what is 6 * 8?

48.

Therefore the second box is 48.

Now that we have both the numerator and denominator, we need to simplify the fraction by dividing the numerator by the denominator.

What is 48 divided by 48?

1.

Therefore 1 goes in the third box.

Answer:

When you are finding a line that is perpendicular, you need to look at the slope. In the format, y=mx+b, the m represents the slope. In this case, the slope (m) of the line is -1/9. A line with a perpendicular slope is the negative inverse. The negative inverse for -1/9 is 9/1. Once you know the slope, you can begin to plug in the new information in order to find the new b (y intercept).

New Line information:

m=9/1, (2,-5) --> this means that x = 2 and y = -5

y=mx+b

-5 = 9/1(2) + b

-5 = 18 + b

-23 = b

Once you find the b, you plug the b and m into the equation y = mx + b

y = 9/1x -23
