Answer:
a. 6Pack of paint brushes for $12.99
b. 5 classes for $64.99
c. 12 pack of paper plates
Step-by-step explanation:
a.
I could buy a 6 pack of paint brushes for $ 12.99
or
buy 6 individual brushes for the price of $ 2.19 each.
6 x $2.19 = $13.14
first option is cheaper
b.
10 classes for s total of $150
$150 ÷ 10 = $15 (price per class)
5 classes for $64.99
$64.99 ÷ 5 = $12.998 (price per class)
c.
12 pack of paper plates for $2.29
25 pack for $4.99
$2.29 ÷ 12 = $0.1908 (price of one plate)
$4.99 ÷ 25 = $0.1996 (price for one plate)

The surf instructor has an initial fee of $12 and charges $8 per hour for lessons, which is represented by the equation y = 8x + 12, where x is the number of hours and y is the total cost. The instructor gives 32 hours of lessons a month to Sandra and 24 hours of lessons a month to Bela. What is the total amount the instructor makes in a month? Sandra: y = 8 (32) + 12. y = 256 + 12. y = 268. The instructor receives 268 dollars a month from Sandra. The instructor makes $ a month.

to rent a car for a trip, four friends are combining their money. The group chat shows the amount of money that each puts in. One expression for their total amount in 189 plus 224 plus q.
a.) Use the Commutative Property to write two equivalent expressions.
b.) If they need $500 to rent a car, find at least two different pairs of numbers that p and q could be.
Answer:
1. 189+224+87 2. 500- 189-224
B. q=87
Step-by-step explanation:
The Commutative Property to write two equivalent expressions are (189+p)+(224+q) or (224+q)+(189+p) and p=44 and q=43 is a pair of numbers or p=45 and q=42 is another pair of numbers which satisfy the condition of car.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
The amount of money that each friend puts in One expression for their total amount in 189 plus 224 plus q.
189+p+224+q
the Commutative Property to write two equivalent expressions.
(189+p)+(224+q)
or (224+q)+(189+p)
Now if they need $500 to rent a car,
then 189+p+224+q=500
413+p+q=500
Then p=44 and q=43 is a pair of numbers or p=45 and q=42 is another pair of numbers.
Hence, the Commutative Property to write two equivalent expressions are (189+p)+(224+q) or (224+q)+(189+p) and p=44 and q=43 is a pair of numbers or p=45 and q=42 is another pair of numbers which satisfy the condition of car.

Answer:
x = 33
Step-by-step explanation:
This picture shows a supplementary angle which means:
angle 1 + angle 2 = 180°
In order to solve for x, you need to add both the angles
(2x + 1) + (4x - 19) = 180° start by simplifying this equation by adding like terms
6x - 18 = 180° you can solve this like a regular inequality now, add 18 to 180°
6x = 198 now divide 6 by 162
x = 33

Answer:
x=31
Step-by-step explanation:
Since these angles are on a straight line, they are supplementary (combine to make 180 degrees. Therefore we can set up an equation to find x.
(5x-16)+(x+10)=180
Drop the parentheses.
5x-16+x+10=180
Combine like terms.
6x-6=180
Add 6 to both sides.
6x=186
Divide both sides by 6.
x=31

Which of the following number lines represents the solution to m/-2 - 7 = -9?
Answer:
Step-by-step explanation:
the answer is a. (the first one)
Number lines are used to represent relationship between numbers at regular intervals
The number line that represents the equation [tex]\frac{m}{-2} - 7 = -9[/tex] is number line (c)
The equation is given as:
[tex]\frac{m}{-2} - 7 = -9[/tex]
Add 7 to both sides of the equation
[tex]\frac{m}{-2} = -2[/tex]
Multiply both sides of the equations by -2
[tex]m = 4[/tex]
This means that, the solution to the equation is [tex]m = 4[/tex]
The number line that represents [tex]m = 4[/tex] is number line (c)
