r = -189
-13 = r/9 + 8
Subtract 8 on both sides
-21 = r/9
Multply 9 on both sides
-189 = r
Answer:
r = -189
Step-by-step explanation:
-13 = r/9 + 8
-13 - 8 = r/9
-21 = r/9
-21 × 9 = r
-189 = r
A team is playing a game and currently has 43 points. If they lose 56 points and then gain 13 points, what will their score be? Write an expression that models this situation and evaluate the expression.
Answer:
(43 - 56) + 13 = 0 points
Step-by-step explanation:
We start with 43 points and loose 56 -- 43-56
then, 13 points are gained = (43 - 56) + 13
simplify and solve:
-13 + 13 = 0
*Note: you can write the expression without the brackets

What is the slope of the line?
Answer:
[tex]m=\frac{-4}{5}[/tex]
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply plug in 2 coordinates into the slope formula to find slope m:
(-3, 1)
(2, -3)
[tex]m=\frac{-3-1}{2-(-3)}[/tex]
[tex]m=\frac{-4}{2+3}[/tex]
[tex]m=\frac{-4}{5}[/tex]
The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $5 and each adult ticket sells for $9.50. The auditorium can hold a maximum of 130 people. The drama club must make at least $950 from ticket sales to cover the show's costs. If xx represents the number of student tickets sold and yy represents the number of adult tickets sold, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
5 x+ 9.50 y = 950, x= 38, y = 80
Step-by-step explanation:
I hope this helps. Have a good day!
One possible solution of the inequalities will be (20, 100).
Formation of inequalities and their solution,To form an inequality choose the variables.Point lying in the common region of the inequalities will be the solution of the inequalities.Given in the question,
Cost of student ticket = $5 eachCost of adult ticket = $9.5 eachLet the number of student tickets sold = x
And the number of adult tickets sold = y
First statement states," Auditorium can hold a maximum of 130 people".
Inequality for the statement will be,
x + y ≤ 130 --------(1)
Second statement states, "The drama club must make at least $950 from the tickets sale to cover the show's cost".
Inequality for the statement will be,
5x + 9.5y ≥ 950 ------ (2)
Now use the utility to graph the inequality,
Since, a point (20, 100) lies in the common region (solution area) of the inequalities,
Therefore, one possible solution will be (20, 100).

what is 113.04 rounded to the nearest hundredths place
it would stay the same cause it can't be rounded to the hundredths place
The decimal number 113.04 rounded to the nearest hundredths place as 113.04.
The given decimal number is 113.04.
Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is less accurate, but easier to use. While rounding a number, we consider the place value of digits in a number.
To round 113.04 to the nearest hundredth consider the thousandths' value of 113.04, which is 0 and less than 5. Therefore, the hundredths' value of 113.04 remains 4.
Therefore, the decimal number 113.04 rounded to the nearest hundredths place as 113.04.

A plane flies 455 miles with the wind in the same time that it takes to fly 400 miles against the wind. If the wind is blowing at a speed of 12mph, whats the speed of the plane in still ai
Answer:
186.55 mphStep-by-step explanation:
Let the speed of the plane be s
The speed of the plane in the same direction is
s + 12The speed of the plane against wind is
s - 12Time = distance/speed
455/(s + 12) = 400/(s - 12)Solving for s
400(s + 12) = 455(s - 12)400s + 400*12 = 455s - 455*12455s - 400s = (400 + 455)*1255s = 10260s = 10260/55s = 186.55 mphWhat is the prime factorization of 135?

Line AB is parallel to line CD. What is the measure of angle CFE?
A 45°
B. 55°
C. 125°
D. 180°
Answer: c
Step-by-step explanation:
A full circle is 360 degrees so half way would be 180 and since theyre parallel you know that you can use the 55 degrees up top to use in ur equation to find cfe
180-55=125
Can't be 45 because the angle on the other side is smaller than cfe and its 55 degrees and cfe has to be wider than 90 degrees because a right angle is 90 degrees and this angle noticeable goes past 90
Can't be 180 because the whole thing equals 180

Suppose y varies directly as x, and y = 7 when x = 2. Find x when y = 21.
Answer:
Step-by-step explanation:
y = k x X
7 = k x 2
7/2 = k...............1
hence y = 7/2x (substituting eq 1)
y = 21
therefore, x = 2y/7
x = 2 x 21
7
x = 2 x 3
x = 6
The required value of x is 6, when y =21 and y directly varies as x.
What is proportion?A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio.
Given that,
y directly varies as x,
Implies that,
y ∝ x
or y = k x (1)
When x = 2 and y = 7, from equation (1)
7 = k × 2
k = 7 / 2
To find the value of x when y = 21,
Substitute values of k = 7 /2 and y = 21 in equation (1),
21 = (7 / 2) × x
3 × 2 = x
x = 6
The value of x when y = 21, is 6.
