Mia has 50$ on a gift card to her favorite coffee shop. Each time she visits the coffee shop sh spends $3.75 on her favorite drink. Write an equation to represent the relationship between n, the number of times she visits the coffee shop, and b, the total balance on her gift card.
Answers
Answer:
50.00-3.75n = b
Step-by-step explanation:
50.00 is the beginning balance she has on the gift card.
If she spends 3.75 every visit, and n represents the number of visits, then 3.75n will tell you how much she has spent with each visit.
1 visit: 50.00 - 3.75(1) = 46.25
2 visits: 50.00 - 3.75(2) = 42.50
3 visits: 50.00 - 3.75(3) = 38.75

we will have to follow given below steps if we want to plot this inequality x is less than or equal to 2.6.
What is linear inequality and examples?A linear inequality is formed by any two real numbers or any two algebraic expressions marked by the symbols "," ">," "," or "." Ones of numerical inequality include 911 and 18>17, while algebraic examples include x+7>y, y10-x, and x y > 11
How do you identify a linear inequality?One of the inequality symbols is present in a linear inequality:. It displays non-equal data in graph style. With the inequality sign in place of the equality sign, a linear inequality appears exactly like a linear equation.
The values of x that satisfy the inequality must be determined before we may graph the inequality x = 2.6 on a number line. This can be done by changing x to a variety of values and observing which ones cause the inequality to hold true. When x is less than or equal to 2.6, we know that the inequality x = 2.6 is true. This means that the inequality will be satisfied for any value of x that is lower than or equal to 2.6. This has a range of inclusive values from -infinity to 2.6. We can use a dotted line spanning from negative infinity to 2.6 to graph the inequality on a number line. We would insert a dot for each number between negative infinity and 2.6, including 2.6 itself, since the dots on the line denote the numbers in the range. The dots on the line represent the integers in the range, which spans from negative infinity to 2.6. (i.e., all numbers less than or equal to 2.6). The open circle at 3 shows that the number is outside of the range, while the solid point at 2.6 indicates that the number is within the range.

There are 15 cousins playing a game. They need to divide evenly into teams. Draw a model to show one way they can split into teams. Then decide if 15 is a prime number or a composite number. Show your work. Answer 15 is a number.
Answers
Answer:
15 is a composite number
Explanation:
We can form 3 groups of 5 people because:
15 = 3 x 5
So, the model that shows this way to split the teams is:
If we can divide 15 into teams, we can say that 15 is a composite number.
A prime number is a number that is only divisible by 1 and by itself. Since 15 is divisible by 3 because we form 3 teams, we get that 15 is not prime, so it is composite.
i have three number cards. the median is 4. if the range is 3, whats the missing number?
Answers
The missing number in those three card are 5 and 2 when the median is 4 and the range is 3.
Median:
Median refers the middle value of the given set of numbers.
Given,
i have three number cards. the median is 4.
Here we need to find the missing number when the range is 3.
Let us consider x and y be the missing number.
We know that, the range is difference of smallest and largest number,
So, we can write it as,
x - y = 3
Now, we know that the median is the middle value
Then it can be written as,
y, 4, x
The smallest possible values of y is 1, 2, and 3
Similarly, the possible values of x is 5, 6, 7
But based on the value of range we have only take the values, 5 and 2.
Because that one is satisfies the condition of range.
Therefore, the missing numbers are 5 and 2.

What is Equation of line?
The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
A line has a slope of 9 and includes points (9, d) and (8, 3).
Now,
We know that,
Slope of line (m) = (y₂ - y₁) / (x₂ - x₁)
⇒ m = (3 - d) / (8 - 9)
⇒ 9 = (3 - d) / (-1)
⇒ - 9 = 3 - d
⇒ d = 3 + 9
