lesson 2.6 Properties & algebraic proofs
Answers
13. You are correct. You multiply the outer 5 with each term inside, and add.
-----------
14. The number 0 goes in the first blank and 8 goes in the second blank. So we have 8+0 = 8. The identity property of addition says that adding 0 to any number leads to the same result. In terms of algebra, x+0 = x.
-----------
15. The fraction 1/8 goes in the first blank and 1 goes in the second blank. We have the equation 8(1/8) = 1. Multiplying any nonnegative number x with its reciprocal 1/x leads to 1.
----------
16. The number 1 goes in the first blank and -4 goes in the next blank. This property is similar to the property mentioned in problem 14. This time we're working with the multiplicative version. We have the equation -4*(1) = -4
----------
17. The letter a goes in the first blank and x+3 goes in the second blank. So the last equation is a = x+3. The transitive property is the idea of us chaining equations together. It's like saying "if A goes to B, and B goes to C, then A goes to C". Think of it like taking a shortcut bypassing B entirely.

If n divided by m equals 7/8,
what does m divided by n equal?
Answers
Step-by-step explanation:
1,
It is found that m divided by n is equal to 8/7.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.
Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, a/ b = a divided in b equal parts.
If n divided by m equals 7/8, then m divided by n equal.
n / m = 7/8
Then m/n = 8/7
Therefore, m divided by n is equal to 8/7.

A baking mix consists of powdered milk, sugar, and flour in a ratio of 3:4:13.
How many pounds of each ingredient do you need to make 4 lb of baking mix?
Answers
Answer:
Sugar = 0.8 lb
milk = 0.6 lb
Flour = 2.6 lb
Step-by-step explanation:
Firstly, we add the ratios = 3 + 4 + 13 = 20
For milk, we have 3/20 * 4 = 12/20 = 0.6 lb
For sugar l, we have 4/20 * 4 = 16/20 = 0.8 lb
For flour = 13/20 * 4 = 52/20 = 2.6
You will need:
[tex]Milk = 0.6 $ lb\\Sugar = 0.8 $ lb\\Flour = 2.6 $ lb[/tex]
Given:
Milk : Sugar : Flour = 3 : 4 : 13
To find the number of pounds of each ingredient required to produce 4 lb of baking mix, solve as follows:
Amount of each ingredient needed = ratio of each ingredient / total ratio value x 4 lb
Thus:
Total ratio value = [tex]3 + 4 + 13 = 20[/tex]
Amount of milk needed = [tex]\frac{3}{20} \times 4 = 0.6 $ lb[/tex]
Amount of Sugar needed = [tex]\frac{4}{20} \times 4 = 0.8 $ lb[/tex]
Amount of Flour needed = [tex]\frac{13}{20} \times 4 = 2.6 $ lb[/tex]
Therefore, you will need the follow amounts to make 4 lb of baking mix:
[tex]Milk = 0.6 $ lb\\Sugar = 0.8 $ lb\\Flour = 2.6 $ lb[/tex]

Point G is the intersection of medians, the centroid. That point divides each median into parts with a 2:1 ratio. The "2" part is the distance between the centroid and the vertex. The "1" part is the distance between the centroid and the side.
FG : GB : BF = 1 : 2 : 3 = 9 : 18 : 27 . . . . . where 18 is given

Rita just bought a car for 15,000. She paid 20% down and borrowed the remainder at an annual interest rate of 9.0%. The loan will be repaid over four years with monthly payments of $298.62. How much is rita's down payment and how much did she borrow?
Answers
Answer:
Rita's down payment is $3000 and she borrowed $12000.
Step-by-step explanation:
The cost of the car is $15000.
Given that she paid 20% down and borrowed the remainder.
So, Rita's down payment= 20% of $15000
[tex]=\frac{20}{100}\times 15000[/tex]
= $3000
As she borrowed the remainder cost, so,
the borrowed amount = 15000-3000
= $12000
Hence, Rita's down payment is $3000 and she borrowed $12000.

Plot the image of point Q under the translation (x, y) + (x - 3, y + 4).
Answers
Answer:
( 2, -1 )
Step-by-step explanation:
The image of the assumed point Q(2, 3)) under the translation is Q'(-1, 7).
What is Translation?Translation is a type of transformation of geometrical figures. After translation, the original figure is shifted from a place to another place without affecting it's size.
Translation of a point (x, y) indicates that the point is moved x units along the X axis and y units along the Y axis,
Here we have to translate the point Q(2, 3).
Point (x, y) is translated as (x - 3, y + 4).
That is the point (x, y) moves 3 units to the left along the X axis and 4 units upwards along the Y axis.
Q(2, 3) after the translation becomes,
Q'(2 - 3, 3 + 4) = Q'(-1, 7)
Hence the point Q(2, 3) under the translation (x - 3, y + 4) is the point Q'(-1, 7).

The length of a rectangle is (5x − 1) cm and the width is (11 − 2x) cm. If the perimeter of the rectangle is 44 centimeters, what is the area of the rectangle?
Answers
Answer:
57 cm²
Step-by-step explanation
l = length
w = width
p = perimeter
(5x - 1) = length
(11 - 2x) = width
44 = perimeter
Formula for the perimeter of a rectangle:
l + l + w + w
2l + 2w = p
Substitute the variables for the length and width with the values given to you by the problem, then solve.
2(5x - 1) + 2(11 - 2x) = 44
(10x - 2) + (22 - 4x) = 44 (Distributive property)
6x + 20 = 44
6x = 24
x = 4
Plug x = 4 back into the length and width.
Length = (5x - 1), (5(4) - 1), (19)
Width = (11 - 2x), (11 - 2(4)), (3)
Area for a rectangle: Length × Width = Area.
19 × 3 = 57 cm²
This is all in cm so answer with cm²

A school printed 315 tickets to the spring dance. There are 255 tickets left. Which equation can be used to find how many tickets have been sold?
Answers
You didn't add any options but here's one that would work.
315 - 255 = 60
When there is a problem asking how many are left, taken, sold, given, etc. You are usually dealing with subtraction.
Hope that helps and have a great day!
Answer:
The last choice (x+255=315 )
Step-by-step explanation:
This is because we know the total number of tickets is 315 and they have 255 left. So, x + 255 = 315. Because you subtracted __ from 315 to get 255. You can rewrite that as __ + 255 = 315 or x + 255 = 315

How do you decide in what way to reorder the terms of expression when simplifying it
Answers
We use the PEMDAS to reorder the terms of expression when simplifying it.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
We use the PEMDAS to reorder the terms of expression when simplifying it.
The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.
Therefore, use PEMDAS to simplify any expression.
