Answer:
Cost of each blank shirt is less than or equal to $ 5.5
Step-by-step explanation:
Let x denotes cost of each blank shirt.
Total number fo shirts bought by Tyina = 12
Amount charged for each shirt to have the club logo = $2.75
So,
Amount charged for 12 shirts to have the club logo = 
As Tyina cannot spend more than $99,
Now solve the inequality.
So,
Cost of each blank shirt is less than or equal to $ 5.5
Answer:
The number is -6.
Step-by-step explanation:
Variable x = a number
Set up an equation:
3x + 12 = -6
Isolate variable x:
3x = -18
x = -6
Check your work:
3(-6) + 12 = -6
-18 + 12 = -6
-6 = -6
Correct!
Answer:
An equation is used when we have paired sets of data to describe how the values in one pair change when we alter the values in the other set.
On the other hand, a series gives a general formula of determining the value of the nth observation when the values have been arranged in increasing order
Step-by-step explanation:
An equation such as; y = 3x+5 models the relation between the response variable y and the predictor variable x. It tells us how y changes when x is altered by a certain magnitude. The value 3 is described as the slope while 5 is the y-intercept.
On the other hand, a series such as; score = 2 + 3n provides a general formula that can be used to determine the score of the nth individual in a sample or population.
As an equation, we have:
69+42=5+(146-x)
You just have to simplify:
111=5+(146-x)
106=146-x
-40=-x
40=x
Your unknown number is 40
