2. Identify the property of equality that justifies the missing step to solve the given equation
Answers
Answer:
Subtraction property of equality
Step-by-step explanation:
Given the equation;
2x + (x+5) = 41
open the parenthesis;
2x+x + 5 = 41 (Associative property)
3x+5 = 41
Subtract 5 from both sides
3x + 5 = 41
3x + 5- 5 = 41 - 5 (Subtraction property of equality)
3x = 36
Divide both sides by 3;
3x/3 = 36/3
x = 12 (Division property of equality)
Hence the required property is Subtraction property of equality

The total rent of the car is $15.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, three students plan to rent a minivan for the weekend and equally share the rental cost.
Let the total money to rent a minivan be x.
Now, share of each student = x/3
Adding two more people, they can each save $24.
x/3- (x+2)/5 =24
5x-3(x+2) =24
5x-3x-6=24
2x=30
x=$15
Therefore, the total rent of the car is $15.

factorize 2xy - 8x + 5y -20
Answers
The factors for 2xy - 8x + 5y -20 is ( 2x + 5 ) ( y - 4 ).
Given 2xy - 8x + 5y -20
By writing like terms on one side
2xy - 8x + 5y - 20
By taking common terms outside we get
2x ( y - 4) + 5 ( y - 4)
By taking common terms we get
( 2x + 5 ) ( y - 4 )
Therefore the factors for 2xy - 8x + 5y -20 is ( 2x + 5 ) ( y - 4 )..

What is linear equation?A linear equation is an equation of the first degree in any number of variables, that can be written in the form ax + b = 0 or ax + by + c = 0, where a, b, and c are real numbers and x and y are variables. The coefficients may be arbitrary expressions, but they do not contain any of the variables. A linear equation is defined by a straight line in the Cartesian plane.
Given is an equation, y = 5x-10, we need to find an equation, when graphed with the given equation, will form a system that has no solution,
So, we know that,
A system of equations will have no solution, if,
a1x + b1y + c1 = 0
a2x + b2y + c2 = 0
If (a1/a2) = (b1/b2) ≠ (c1/c2), then there will be no solution.
Therefore, the only equation that fulfills this condition is y = 5(x-2)
Hence, the equation when graphed with the given equation, will form a system that has no solution is y = 5(x-2)

Ms. Thornton is buying treats for her top 10 algebra students in each of her two classes (20 treats total). She’s only willing to spend $30 and finds individualized candy packs for $1.75 each. What is the maximum number of packs that she will be able to buy? Will that be enough for all of her students?
Answers
Answer:
Mrs Thornton can buy almost 17 candy packs if she has $30 to spend and one pack cost $1.75.
No, it will not be enough because total students are 20 and total candy packs that can be bought are 17.
Step-by-step explanation:
Total treats to buy = 20
Total cost to spend = $30
Price of one candy pack = 1.75
We need to find:
a) What is the maximum number of packs that she will be able to buy?
Price of 1 candy pack = $1.75
If she spends $30, divide 30 by 1.75 to get the number of candy packs she can buy
Number of candy packs = [tex]\frac{30}{1.75} = 17.14 \approx 17[/tex]
So, Mrs Thornton can buy almost 17 candy packs if she has $30 to spend and one pack cost $1.75
b) Will that be enough for all of her students?
No, it will not be enough because total students are 20 and total candy packs that can be bought are 17.
