Answer:
13m + 8
Step-by-step explanation:
Distribute
(20m + 3) - 1(7m - 5)
(20m + 3) - 7m + 5
Eliminate redundant parentheses
(20m + 3) - 7m + 5
20m + 3 - 7m + 5
Add the Numbers
20m + 3 - 7m + 5
20m + 8 - 7m
Combine Like Terms
20m + 8 - 7m
13m + 8
Solution
13m + 8
The difference of the given equation i.e. (20m+3)-(7m-5) should be considered as the 13m + 8.
Calculation of the difference:Since the equation is (20m+3)-(7m-5)
So,
= 20m + 3 - 7m + 5
= 13m + 8
Hence, The difference of the given equation i.e. (20m+3)-(7m-5) should be considered as the 13m + 8.

A high school championship football game was attended by 1580 fans. there were 640 were out of state fans at the game. the other fans were local.
Answer:
Step-by-step explanation:
1580-640=940 were local
No. of local fans = 940
What is subtraction?Subtraction is one of the four basic arithmetic operations in mathematics. It represents the operation of removing objects from a collection. The minus sign signifies subtraction −.
Example: There are nine oranges arranged as a stack, out of which four oranges are transferred to a basket, then there will be, 9 – 4 oranges left in the stack, i.e. five oranges.
Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5.
Subtraction is not only applied to natural numbers but also can be incorporated for different types of numbers such as negative numbers, fractions, rational & irrational numbers, decimals, functions, matrices and vectors.
Given,
Total fans attended championship = 1580
No. of out of state fans = 640
No of local fans = total fans - no. of out of state fans
= 1580 - 640
No of local fans = 940
Hence, there were 940 local fans who attended football championship.

The Chambers family has driven 603 miles at a constant speed of 67mph. How many hours have they been driving. Use d = rt to solve.
Write an equation for the situation that will represent the distance for any time.
Answer:
d = 67t
and
eqn d = 67t represents d over time.
Step-by-step explanation:
part one : find the hours they have been driving
d = 603 miles driven
r = 67 mph
t = ?
r = d/t
rt = d
t = d/r
t = 603/67
t = 9
unit = in hours
they have been driving for 9 hours.
part 2 : find an equation for the situation that represents distance for any time
t is the independent variable
d will represent the dependent variable
let r represent the slope
d = rt
d = 67t
therefore the eqn d = 67t represents d over time.

What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
Number of cups of raisins Susan have = 3/4 cups
The number of 3/8 servings in 3/4 cups of raisins:
= 3/4 ÷ 3/8
= 3/4 x 8/3
= (3 x 8) / (4 x 3)
= 2 servings
Thus,
There are two 3/8 cup servings in 3/4 cups of raisins.
The number of 3/8 cups of servings = 2 servings.

The value of the given expression 5² + 2³ is 33
What are expressions?An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.
For example, 2x+3
The given expression, 5² + 2³, involves two operations: squaring and cubing.
The first operation, 5², means that we need to multiply 5 by itself, which results in 25.
The second operation, 2³, means that we need to multiply 2 by itself three times, which results in 8.
Therefore, 5² + 2³ is equivalent to 25 + 8, which gives us 33 as the final answer.
In other words, the value of the given expression is 33. This calculation involves basic arithmetic operations and can be easily solved using a calculator or mental math skills.

The area of abcd

Answers

The area of square ABCD is 10 cm^2 . Show that x^2 + 6x = 1 (requires diagram which I will draw on the whiteboard).
The area of a square is the length of one side squared (multiplied by itself), so for a square with side length 3, the area will be 32 or 3 x 3, which = 9. For a square with side length x, the area will be x2 .Given that the length of one side is 3 + x, the area will be (3+x)2 This can be written as (3+x) * (3+x), and to expand these brackets we will use the 'crab claw' method. We will take the first value in the first bracket, and times it by both values of the second bracket. So we will multiply 3 by 3 which is 9, and then 3 by x which is 3x. We will then take the second value in the first bracket and multiply is by both values in the second bracket. So we will multiply x by 3 which is 3x, and then x by x, which is x2. Now we will add together all the the values we have just found: x2 + 3x + 3x + 9. Because the only like terms are 3x and 3x, and 3x + 3x = 6x, the final equation we form after expanding the brackets will be x2 + 6x + 9.. Given that the area of the square is given as 10cm2, 10 must be equivalent to x2 + 6x + 9, so we form the equation x2 + 6x + 9 = 10. When balancing equations, you must do whatever you do on one side to the other side. Therefore if we take 9 away from the left hand side, we must take 9 away from the right hand side (10 - 9 = 1), leaving us with x2 + 6x = 1, and completing the question.
