Alto and Brian both ordered the same size pizzas and Marco's Pizza;
however, they ordered different toppings. Marco's charges an additional
fee for toppings, but all toppings cost the same. Alto got pepperoni,
banana peppers, and black olives on his pizza for a cost of $15.74. Brian
order mushrooms and eggplant of his pizza and paid $14.49. Using this
information, write an equation for the cost of a pizza, C, as a function of
the toppings, t, ordered. *Hint: slope intercept form and you will need the
slope formula
Answer:
Cost of pizza = 1.25x + 11.99
Step-by-step explanation:
Since Toppings cost the same and the pizza orders are of same size :
Alto ordered for 3 Toppings + pizza = 15.74
Brian ordered for 2 toppings + pizza = 14.49
Hence the cost per topping and pizza could be found :
Cost per topping :
15.74 - 14.49 = 1.25
Hence, slope = 1.25
The intercept, c represents the cost of pizza alone :
Cost of pizza + 2 Toppings = 14.49
Cost per topping = 1.25
Cost of pizza = 14.49 - 2(1.25)
Cost of pizza = 14.49 - 2.50 = 11.99
Expressing in slope - intercept form :
y = mx + c
m = slope ; c = intercept
Cost of pizza = 1.25x + 11.99

(Brainliest for correct) You have decided to buy a Honda Accord LX, but you are concerned about the value of the car depreciating over time. You search the Internet and obtain the following information. The suggested retail price is $20,025. The depreciation per year is $1,385. What is the value of the car in dollars for 1 year of ownership, and how did you get that answer?
To find the value of the car after 1 year, subtract the amount it depreciates from the value of the car:
20,025 - 1,385 = 18,640
After 1 year the car is valued at $18,640
Answer:
$18640
Step-by-step explanation:
For year 1: Depreciated value is $1385.
We will minus that amount from the actual worth of car i.e. $20,025
So,
= $20,025 - $1385
= $18640

Micah pays 54$ for an item originally priced 60$. What percentage of the original price was his discount?
Answer: The percentage of the original price was his discount = 10%
Step-by-step explanation:
Given: original price = $60
Price after discount = $54
Discount = Price after discount - original price
= $ (60-54) = $6
The percentage of the original price was his discount = [tex]\dfrac{Discount}{Original\ price}\times100[/tex]
[tex]=\dfrac{6}{60}\times100\%\\\\=\dfrac{1}{10}\times100\%\\\\=10\%[/tex]
Hence, the percentage of the original price was his discount = 10%

Answer:
30= 2×3×5
24= 2cubed×3
72= 2cubed×3squared
100=2squared×5squared
Answer:

An equilateral triangle with side length 1 cm is shown in the diagram, work out the height of the triangle.
Give your answer rounded to 1 DP.
Answer:
0.9 cm
Step-by-step explanation:
c is the length of the side. a is the altitude. b is the base. a is the vertical bisector if the base, so the base is 0.5 cm.
c² = a² + b²
1² = a² + 0.5²
1² - 0.5² = a²
1 - 0.25 = a²
√0.75 = a

4x + 3(4x + 7) = 4(7x + 3)
Answer: 1
Step-by-step explanation:4x + 3(4x + 7) = 4(7x + 3) + -3
Reorder the terms:
4x + 3(7 + 4x) = 4(7x + 3) + -3
4x + (7 * 3 + 4x * 3) = 4(7x + 3) + -3
4x + (21 + 12x) = 4(7x + 3) + -3
Reorder the terms:
21 + 4x + 12x = 4(7x + 3) + -3
Combine like terms: 4x + 12x = 16x
21 + 16x = 4(7x + 3) + -3
Reorder the terms:
21 + 16x = 4(3 + 7x) + -3
21 + 16x = (3 * 4 + 7x * 4) + -3
21 + 16x = (12 + 28x) + -3
Reorder the terms:
21 + 16x = 12 + -3 + 28x
Combine like terms: 12 + -3 = 9
21 + 16x = 9 + 28x
Solving
21 + 16x = 9 + 28x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-28x' to each side of the equation.
21 + 16x + -28x = 9 + 28x + -28x
Combine like terms: 16x + -28x = -12x
21 + -12x = 9 + 28x + -28x
Combine like terms: 28x + -28x = 0
21 + -12x = 9 + 0
21 + -12x = 9
Add '-21' to each side of the equation.
21 + -21 + -12x = 9 + -21
Combine like terms: 21 + -21 = 0
0 + -12x = 9 + -21
-12x = 9 + -21
Combine like terms: 9 + -21 = -12
-12x = -12
Divide each side by -12.
x = 1

Step-by-step explanation:
The value of x for equation x /45 = 3 is 135, value of expression −5.8 + (−2.5) is -8.3, the sale price is $319.20, volume of cube is 125 cubic centimeter, y = x /8 represents a proportional relationship.
What is Expression?An expression is combination of variables, numbers and operators.
1. The given equation is x /45 = 3
Now value of x is 45×3
x=135
3. The expression is −5.8 + (−2.5)
−5.8 −2.5
The value of expression is -8.3
4.To find the sale price after a 20% discount, we need to subtract 20% of the original price from the original price:
20% of $399 = (20/100) x $399 = $79.80
Sale price = $399 - $79.80 = $319.20
Therefore, the sale price is $319.20.
5. The side length of cube is 5 cm
Volume = 5³
=125 cubic centimeter
6. y = 8/ x equation represents a proportional relationship
7. 5 ft² is area of the wall will the game board cover
9. The given expression is 5 /8 x 4 /5
20/40
1/2
Hence, the value of x for equation x /45 = 3 is 135, value of expression −5.8 + (−2.5) is -8.3, the sale price is $319.20, volume of cube is 125 cubic centimeter, y = x /8 represents a proportional relationship.
