It’s 13 - 17
It’s unit 2
lesson 2.6 Properties & algebraic proofs
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.

25% of 96 is what number?
Answer: 24
Step-by-step explanation:
25% = 0.25
0.25 * 96 = 24
slope-intercept from two points (4,-8) and (8,5)
Here you go :)
Slope is equal to the change in y over the change in x or rise over run:
m = change in y/change in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise):
m=y2−y1/x2−x1
Substitute in the values of x and y into the equation to find the slope:
m=5−(−8)/8−(4)
Simplify:
m=13/4
Substitute the value of m into the slope-intercept form of the equation, y = m x + b :
y=(13/4)x+b
Substitute the value of x into the slope-intercept form of the equation, y = m x + b .
y = ( 13/ 4 ) ⋅ ( 4 ) + b
Substitute the value of y into the slope-intercept form of the equation, y = m x + b .
− 8 = ( 13/ 4 ) ⋅ ( 4 ) + b
Rewrite the equation as ( 13 4 ) ⋅ ( 4 ) + b = − 8 .
( 13/ 4 ) ⋅ ( 4 ) + b = − 8
Cancel the common factor.
13/ 4 ⋅ 4 + b = − 8
Rewrite the expression.
13 + b = − 8
Move all terms not containing b to the right side of the equation.
b = − 21
The values of the slope and y-intercept are m = 13 4 and b = − 21 .
m = 13 4
b = − 21

Given that,
The total money spent on granola is $3.75.
And, the amount of granola is 3 pounds.
The unit rate for the given case can be found using unitary method as,
Money spent for 3 pounds = $3.75
Then, money spent for 1 pound = 3.75/3 = $1.25
Hence, the rate of granola $1.25 per pound.

−z + 26 = 12 what is Z
Answer:
z = 14
Step-by-step explanation:
subtract 26 from both sides to isolate the variable, you should get: -z = -14
then divide both side by the negative sign, so you should get: z = 14
Answer:
z=14
Step-by-step explanation:
−z + 26 = 12
-z=12-26
-z=-14

The supplement of an angle is 30 less than six times the angle. Find the angle and its supplement.
Answer:
The angle is 30
and its supplement is 150
Step-by-step explanation:
Let the angle be x
The supplement of an angle is 180 minus that angle
So the supplement here is 180 -x
Now, the supplement of the angle is 30 less than 6 times the angle;
Thus;
180-x = 6x -30
180 + 30 = 6x + x
7x = 210
x = 210/7
x = 30
the supplement is 180 - x = 180 -30 = 150

How do you decide in what way to reorder the terms of expression when simplifying it
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.
