Molly and Maddie are clothes shopping. Molly has $100.00 and a coupon for a $5.00 discount at a clothing store where each shirt costs $15.00. Molly thinks that she can buy 8 shirts, but Maddie says that Molly can buy 7 shirts. The equations they used to model the problem are listed below.
Solve each equation algebraically, justify your steps, and determine who is correct and why.
Molly's equation
15x + 10 = 100
Maddie's equation
15x - 10 = 100
Step-by-step explanation:
let us start with
Molly's equation
15x + 10 = 100
solving for x we have
15x=100-10
15x=90
x=90/15
x=6
Maddie's equation
15x - 10 = 100
solving for x we have
15x=100+10
15x=120
x=120/15
x=8

What is an equation of the line that passes through the point (5, 1) and is parallel to
the line x + y = 9?
Answer:
Step-by-step explanation:
y = -x + 9
y - 1 = -(x - 5)
y - 1 = -x + 5
y = -x + 6
The equation of the line that passes through the point ( 5, 1 ) and parallel to the line x + y = 9 is x + y = 6.
Here,
The point is given as ( 5, 1 ).
The equation of line is parallel to the line x + y = 9.
What is Equation of line?
The general equation of straight line is given as, [tex]y - y_{1} = m ( x-x_{1} )[/tex]
where, m is slope of line and ( x₁ , y₁) is point.
Now,
The equation of line is parallel to the line x + y = 9.
Hence, both line have same slope.
The slope of line x + y = 9 is given as,
⇒ y = -x + 9
compare with equation of line y = mx + c , we have;
Slope = -1
The equation of the line passes through the point ( 5, 1 ) and slope -1 is;
y - 1 = -1 ( x - 5)
y - 1 = -x + 5
y = -x + 6
Hence, The equation of the line that passes through the point ( 5, 1 ) and parallel to the line x + y = 9 is x + y = 6.

From the table, we have:
sin(π) = 0
Next, we calculate the value of y for other values of x
When x = 7π/6, we have:
sin(7π/6) = -1/2
When x = 5π/4, we have:
sin(7π/6) = -√2/2
When x = 4π/3, we have:
sin(4π/3) = -√3/2

Fiona is going to the grocery store for watermelons and pineapples. Watermelons cost $7 each and pineapples cost $4 each. Fiona has a total of $30 to spend. Use the equation 7w + 4p = 30 to answer the question below. If Fiona buys 3 watermelons, what is the maximum number of pineapples she can buy?
Answer:
The maximum number of pineapples Fiona can buy is 2.
Step-by-step explanation:
If Fiona buys 3 watermelons, thats 7 x 3 = 21. Then, (total amount of money) 30 - 21 = 9. To find how many pineapples she can buy, see how many times 4 goes into 9 (which is 2). Hope this helps!
Answer:
9.

The number of loaves of bread that can be baked is proportional to the amount of flour used. Determine the number of loaves that can be baked with 15 cups of flour
Answer:
3 loaves
Step-by-step explanation:
See attachment for complete question.
Represent Loaves with L and Flour with F
Since L is proportional to F, the relationship can be defined as:
L = kF
Where k represent the constant of proportionality
When L = 4, F = 20
Substitute these values in the above formula.
4 = k * 20
Divide both sides by 20
4/20 = k
⅕ = k
k = ⅕
To solve for 15 cups of Flour, we have:
F = 15
Substitute 15 for F and ⅕ for k in L = kF
L = ⅕ * 15
L = 3
Hence, 3 loaves will be baked using 15 cups of flour

8z - 22 = 3(3z + 11) - z
Answer:
There are no solutions.
Step-by-step explanation:
8z−22=3(3z+11)−z
Step 1: Simplify both sides of the equation.
8z−22=3(3z+11)−z
8z+−22=(3)(3z)+(3)(11)+−z(Distribute)
8z+−22=9z+33+−z
8z−22=(9z+−z)+(33)(Combine Like Terms)
8z−22=8z+33
8z−22=8z+33
Step 2: Subtract 8z from both sides.
8z−22−8z=8z+33−8z
−22=33
Step 3: Add 22 to both sides.
