A local pizza shop has a membership program for frequent buyers. The membership costs $25 per month and members get a discounted price of $1.25 per slice of pizza. Justin purchased a membership to this pizza shop. How much would Justin have to pay the pizza shop if he bought 12 slices of pizza this month? What would be the monthly cost for x slices of pizza?
PLEASE HURRY!
The amount that Justin would have to pay the pizza shop if he bought 12 slices of pizza this month is $15.
The monthly cost for x slices of pizza is $25 + $1.5x
What is the total cost?In order to determine the amount that Justin would have to pay the pizza shop if he bought 12 slices of pizza can be determined by multiplying the cost per pizza by the number of pizzas sold.
Multiplication is the operation used in mathematics that is used to calculate the product of two or more numbers. The sign that is used to represent multiplication is x.
Cost of 12 slices of pizza = discounted price x number of slices bought
$1.25 x 12 = $15
The monthly cost is the sum of the membership fee and the total cost of the pizzas bought
Monthly cost = monthly membership fee + cost of the slices
Monthly cost = monthly membership fee + (discounted price x number of slices bought)
$25 + (1.25 x x)

Solve for the value of q.
Answer:
q = 20
Step-by-step explanation:
The two angles shown in the image are supplementary angles which means their sum is equal to 180°
We can find the value of q using the following equation:
78 + 5q + 2 = 180 add like terms
80 + 5q =180 subtract 80 from both sides
5q = 100 divide both sides by 5

There are 15 year 12 pupils in a football club, out of a total of 46 pupils. write this proportion as a percentage. give your answer correct to 1 decimal place when appropriate.
In the football club, the percentage of 15-year 12 pupils out of 46 pupils is equal to 30%.
The proportion can be found by dividing the number of 15-year pupils by the total number of pupils. Therefore;
number of 15-year pupils / total number of pupils = 12 / 46 = 0.260
Rounding it to one decimal;
0.260 = 0.3
Percentage in mathematics can be defined as a number or a rate in each hundred. A decimal value can be converted into a percentage by multiplying the decimal value by 100.
0.3 × 100 = 30%
Therefore, the proportion of the 15-year pupils in the football club is 12/46 and this proportion can be written in percentage as 30%.

A pizza shop offers a choice of 3 sizes (small, medium, and large) and 7 different toppings. Different pizzas can be created by changing the size and/or the choice of toppings. If Cody wants to order a pizza with exactly 2 different toppings, how many different pizzas can he create?
1. 6
2. 21
3. 63
4. 121
Using permutation and combination we can calculate that she can get 63 different types of pizza.
Permutations and combinations are the various ways in which elements from a set may be chosen, typically without replacement, to create subsets. This choice of subsets is known as a permutation when the order of the selection is taken into account, and as a combination when it is not.
The total of the decisions we make given an initial set of n items is known as a combination. Permutation, on the other hand, counts the number of possible arrangements of n separate items. This will help us recall that combinations place more emphasis on choice than on placement, order, or arrangement.
Now Cody can get any two toppings out of the 7.
Number of ways in which Cody can pick 2 toppings out of 7 is given by the use of combination,
7C2 = 21 different ways.
Again the number of ways in which 3 different pizza s can be selected is given by 21 × 3 = 63 ways.
Hence Cody can create 63 different pizzas.

If a segment has one endpoint at (0,0) and a midpoint at (4,-6) where is the other endpoint?
The coordinates of the second end point of the line is (8, -12).
What is defined as the mid point of coordinate?For the points on the coordinate axes, the midpoint formula is defined. Let the endpoints of the a line segment be (x)1, (y)1, and (x)2, (y)2. The midpoint is equal to one-half of the sum of the two points' x-coordinates and half of a sum of the two points' y-coordinates.For the given question;
The end point of the line segment is (0,0).
The mid-point of the line segment is at (4,-6).
Thus,
(x₁, y₁) = (0,0)
(x₂, y₂) = ?
(xₐ, yₐ) = (4,-6)
Thus, the formula for finding the mid point is;
xₐ = (x₁ + x₂)/2
Put the values;
4 = (0 + x₂)/2
On simplification;
x₂ = 8.
For y coordinate;
Thus, the formula for finding the mid point is;
yₐ = (y₁ + y₂)/2
Put the values;
-6 = (0 + y₂)/2
On simplification;
x₂ = -12
Thus, the coordinates of the second end point of the line is (8, -12).

Omar has been training for the Candlewood Footrace. The first week he trained, he ran 7 days and took the same two routes each day: 3 miles around the track before work and a longer route through his neighborhood after work. By the end of the week, Omar had run a total of 63 miles.
Which equation can you use to find how many miles, x, Omar ran each day after work?
The equation that can be use to find the how many miles, x, Omar ran each day after work is x = (Total distance he ran in one week - The total distance he run before the work in one week) ÷ 7, he ran 6 miles each days after work
The total number of days he run = 7 days
Total distance he ran in one week = 63 miles
The distance he run before the work = 3 miles
The total distance he run before the work in one week= 7×3
= 21 miles
The total distance he run after the work = 63 - 21
= 42 miles
The equation that can use to find how many mile x, Omar ran each day after work = (Total distance he ran in one week - The total distance he run before the work in one week) ÷ 7
Substitute the values in the equation
= 42/7
= 6 miles
Hence, the equation that can be use to find the how many miles, x, Omar ran each day after work is x = (Total distance he ran in one week - The total distance he run before the work in one week) ÷ 7, he ran 6 miles each days after work

Using properties of exponents, the simplified expression for 5³ x 5^(-5) is given by:
A. 1/(5²).
How do we multiply two terms with the same base and different exponents?The exponent property applied to multiply the terms with the same base but different exponents is that we keep the bases and then add the exponents.
For this problem, the expression is given as follows:
5³ x 5^(-5)
Hence:
The base is of 5.The exponents are of 3 and -5.Adding the exponents, we have that:
3 + (- 5) = 3 - 5 = -2.
Hence the simplified expression is:
5³ x 5^(-5) = 5^(-2).
When a number has a negative exponent, we can move it to the denominator, then the exponent becomes positive, hence:
5^(-2) = (1/5)² = 1/5² = 1/25.
