Step-by-step explanation:
Solve for X then Solve for angles 7X-40 and 2X+60
Answer:
X = 20
Angles are both equal to 100 degrees
Step-by-step explanation:
Assuming that 7x-40 = 2x +60
1. Order of Operations
2. 5x = 100
3. divide 100 by 5
4. x = 20
5. Plug 20 into both equations
6. 7(20) - 40 = 100
2(20) + 60 = 100
7. Both angles are equal to 100 degrees

Derek analyzed the relationship between the mean number of points scored per game by a basketball team and the team's mean home attendance for several seasons. Derek uses the function y=−7,628+325.5x to describe the data. In the function, x represents the mean number of points scored per game, and y represents the mean home attendance. If the team's mean number of points scored per game is 60 next season, what does the model predict that the team's mean home attendance will be? The model predicts that the mean home attendance will be _____ .
Answer:
Step-by-step explanación
0.02
When the mean number of points scored per game next season is 60, the model predicts that the mean home attendance will be 11902
The function that predicts the attendance is given as:
[tex]y = -7628+325.5x[/tex]
When the mean number of points scored per game next season is 60, it means that the value of x is 60
i.e. x = 60
Substitute 60 for x in the function
So, we have:
[tex]y = -7628+325.5 \times 60[/tex]
Evaluate the product
[tex]y = -7628+19530[/tex]
Add -7628 and 19530
[tex]y = 11902[/tex]
Hence, the model predicts that the mean home attendance will be 11902

Susan bought a pair of jeans for $20.95 and a shirt for $11.50. She paid with $40.00. How much was her change?
Answer:

What is linear equation in one variable?
A linear equation in one variable is an equation which has maximum of one variable of order 1. It is of the form ax + b =0, where x is the variable.
Solving Linear Equation in one variableFor solving an equation having one variable, the following steps are followed:
Step1: Using LCM, clear the fractions if any.Step2: Simplify both sides of the equation.Step 3: Isolate the variable.According to the given question
We have, a linear equation in variable r.
2r +7 =16
⇒ 2r + 7 -7 = 16 -7
⇒ 2r = 9
⇒ r = 9/2
Hence, the value of r is 9/2 for the given linear equation 2r + 7 = 16.

What’s 123.45 + 67.891
Step By Step?
Answer:
123.45 + 67.891 = 191.341
Step-by-step explanation:
I don't know really know how to explain but I'll try to. So since 123.45 is the larger decimal so you put it first then below it you put 67.891.(not that it is necessary)
Then add a zero to 124.45. Meaning it will be 123.450. (It is the same number, we just have to add a zero there.)
Add then just add like you normally do. Just try doing it and you'll see.
Mr. Olivera wants to buy a bicycle that costs $184 for each of his two children. He plans to save the $9 he usually spends for lunch to buy the bikes.

The actual number of days required to buy a bicycle will be 20 days.
Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
Mr. Olivera wishes to purchase a $184 bicycle for each of his two children. He intends to save the $9 he normally spends on lunch to purchase the bikes.
Let 'x' be the number of days. Then the inequality is given as,
9x ≤ 184
Simplify the equation, then we have
9x ≤ 184
x ≤ 184 / 9
x ≤ 20.44
The actual number of days required to buy a bicycle will be 20 days.
