56 divided by 7
=8
Answer: it should be 8.
Step-by-step explanation:
Step 1. Factor in the given variables.
(xy + 1) ÷ 7 becomes ((5)(11) + 1) ÷ 7
Step 2. Do the first part in parentheses
so (5) x (11) which is 55.
Step 3. Add together the full parentheses
so 55 + 1 which is 56
Final step, divide.
56 divided by 7 equals 8.

To find the circumference of a circle, multiply the diameter with π (pi)
Formula: 2πr (2 × radius) (π = 3.14)
In the problem...
-----------------------------------------------------------------------------------------------------------------
We can multiply 3.14 by 8 to get the circumference.
3.14 × 8 = 25.12
Hence, 25.12 is the answer, but we can do it another way.
Let me know if you have any questions.

A line is shown on a coordinate grid. The x-axis values are from negative 10 to positive 10 in increments of 2 for each grid line. The y-axis values are from negative 5 to positive 5 in increments of 1 for each grid line. The line passes through the ordered pairs negative 8, 4, and 0, 0, and 8, negative 4. A shaded right triangle is formed so that its hypotenuse is from ordered pair 0, 0 labeled as O to negative 4, 2 labeled as A, one leg is from 0, 0 to negative 4, 0, and the second leg is from negative 4, 0 to negative 4, 2. Another shaded right triangle is formed with the hypotenuse from negative 4, 2 to negative 6, 3, labeled as B, one leg is from negative 4, 2 to negative 6, 2, and the second leg is between negative 6, 2 to negative 6, 3.
Which statement about the slope of the line is true? (1 point)
Select one:
a. It is −2 throughout the line.
b. It is fraction negative 1 over 2 throughout the line.

How can you express 11 x 7 using the distributive property?
Answers
Answer 77
Step-by-Step Explanation:
The following are the cases where 11 x 7 can be expressed using the distributive property.
11 x (4 + 3) = 11 x 4 + 11 x 3
11 x (6 + 1) = 11 x 6 + 11 x 1
11 x (10 - 3) = 11 x 10 - 11 x 3
11 x (9 - 2) = 11 x 9 - 11 x 2
11 x (10 - 3) = 11 x 10 - 11 x 3
11 x (9 - 2) = 11 x 9 - 11 x 2
What is an expression?
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
11 x 7
The distributive property of multiplication over addition.
a x (b + c) = a x b + a x c
The distributive property of multiplication over subtraction.
a x (b - c) = a x b - a x c
Now,
We can write 11 x 7 in many different cases.
Here are the four cases where we can use the distributive property.
11 x 7 can be written as:
11 x (4 + 3) = 11 x 4 + 11 x 3
11 x (6 + 1) = 11 x 6 + 11 x 1
11 x (10 - 3) = 11 x 10 - 11 x 3
11 x (9 - 2) = 11 x 9 - 11 x 2
Thus,
The following are the cases where 11 x 7 can be expressed using the distributive property.
11 x (4 + 3) = 11 x 4 + 11 x 3
11 x (6 + 1) = 11 x 6 + 11 x 1
11 x (10 - 3) = 11 x 10 - 11 x 3
11 x (9 - 2) = 11 x 9 - 11 x 2
11 x (10 - 3) = 11 x 10 - 11 x 3
11 x (9 - 2) = 11 x 9 - 11 x 2
