Answer:
b = -3
Step-by-step explanation:
Math is my explanation!
Answer and Step-by-step explanation:
To find the value of b, we have to get it by itself.
First, start off by subtract 7 from both sides of the equation.
2b = -6
Now, divide both sides of the equation by 2.
b = -3
The answer is b = -3.

Answer:
5 hours and 30 min.
Step-by-step explanation:
90/60 = 1.5 = 1 hour and 30 min.
200/50 = 4 = 4 hours

Find the value of x.
Equation?
X?
Answer:
(12x + 19) + (22x - 9) = 180°, x = 5
Step-by-step explanation:
Supplementary angles are 2 angles that adds up to 180°
Another words,
(12x + 19) + (22x - 9) = 180°
Now we solve for x by combining like terms:
34x + 10 = 180°
Subtract 10 on both sides:
34x = 170°
Divide 34 on both sides:
x = 5
Which value of kkk makes 5-k+12=165−k+12=165, minus, k, plus, 12, equals, 16 a true statement?

8.1 Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
2 2 • k
2 = — = —————
1 k
9.1 Pull out like factors :
2 - 2k = -2 • (k - 1)
10.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
-2•(k-1)
———————— • k = 0 • k
k
Now, on the left hand side, the k cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
-2 • (k-1) = 0
Equations which are never true:
10.2 Solve : -2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
10.3 Solve : k-1 = 0
Add 1 to both sides of the equation :
k = 1
Step-by-step explanation:
Equations are expressions separated by an equal sign. The value of k that will make the equation true is -1
Equations and expressionsGiven the equation expressed as
5−k+12=16
We need to find the value of "k" that will make the equation equal
Given
5−k+12=16
Collect the like terms
17 - k = 16
Subtract 17 from both sides
17 - k - 17 = 16 - 17
k = 16 - 17
k = -1
Hence the value of k that will make the equation true is -1

Step-by-step explanation:
Elena is programming a video game. She needs to simulate the power-up that the player gets when they reach a certain level. The computer can run a program to return a random integer between 1 and 100. Elena wants the best power-up to be rewarded 15% of the time. She could use the computer to simulate the player getting the best power-up at least 2 out of 3 times.
Which of the following matches the results to get the best power-up at least 2 out of 3 times.
1 Elena could have the computer generate 3 random integers between 1 and 100. If at least 1 of the numbers are between 1 and 15, then the player got the best power-up at least twice.
2 Elena could have the computer generate 3 random integers between 1 and 100. If at least 2 of the numbers are between 1 and 15, then the player got the best power-up at least twice.
3 Elena could have the computer generate 3 random integers between 1 and 100. If at least 2 of the numbers are between 1 and 30, then the player got the best power-up at least twice.

On the southeast corner of Millennium Park, there is a garden walk. It is marked off in red in the drawing below. Side C, the hypotenuse of the triangle, shows the row along which flowers will be planted.
⦁ If side a measures 90 feet and side b measures 120 feet, how many feet of flowers will be planted along side c, the hypotenuse of the triangle? Show your work and explain your reasoning. (2 points)
⦁ Calculate the area of the red triangle to find the area of the garden. Show your work. (2 points)
⦁ Millennium Park has an outdoor concert theater. Before a concert, the area reserved for special seating is roped off in the shape of a triangle as shown below. How can the converse of the Pythagorean theorem help you determine whether the roped off area is in the shape of a right triangle? (2 points)
⦁ The front of the stage, side C, is 50 feet long. A 40-foot rope runs along the side of square B. A 30-foot rope runs along the side of square A. Is the roped off area, triangle ABC, a right triangle? Explain. (2 points)
e) The diagonal of square A, marked off by the red stars, is where the concession stand is located. A local high school band is performing at the outdoor theater on a summer evening. The band has a school banner that is 40-feet long, and band members would like to hang it across the concession stand to let people know they are performing. Estimate the length of the concession stand to determine if the school banner can fit across the length of the concession stand. Show your work and explain your reasoning. (2 points)
Step 2: Finding distance on the coordinate grid
⦁ This is a blueprint drawing of the stage area at Millennium Park. The length of one square on the grid is equal to 5 feet. According to the blueprint, the length of the diagonal of square C is 60 feet. Is that correct? Explain. (2 points).
b) If the blueprint is drawn on the coordinate plane with vertices (1, 5) and (11, 15) for the corners labeled with red stars, would that be an accurate representation of the length of the diagonal of the square C? Show your work and explain your reasoning. (4 points—2 points for finding the length of the diagonal; 2 points for explanation)
Step 3: Using the Pythagorean theorem to find the unknown
At another park in Chicago, neighbors get together to plan a community garden. Plans for the community garden are shown below.
a) The members of the gardening group plan to build a walkway through the garden as formed by the hypotenuse of each of the four triangles in the drawing. That way, the gardeners will be able to access all sections of the garden. Calculate the length of the entire walkway to the nearest hundredth of a yard. Show your work. (4 points—1 point for each length calculation and 1 point for the total distance)
⦁ Is the value you just wrote for the total length of the walkway a rational or irrational number? Explain. (2 points)
⦁ The group is planning to build a fence around the garden. How many yards of fencing materials do they need for the fence? Show your work. (3 points—2 points for finding the value of side b and 1 point for finding the perimeter of the garden)
Answer:
side c = 150 feet of flowers
Area = 5400 feet squared
concert question:
The converse of the Pythagorean theorem can help you determine whether the roped off area is in the shape of a right triangle because you use the side lengths of each square and enter them into the equation, and if the equation is true, then it is a right triangle
Concession stand question:
The school banner can fit across the length of the concession stand
the following information is missing
The length if the sides: c is 50 feet long, b is 40 foot long, and a is 30-foot long.
The distance between the two red stars of the picture makes the hypotenuse of a right triangle, where two sides of length a (30 ft) are the legs. From Pythagorean theorem, diagonal of square A is:
diagonal² = 30² + 30²
diagonal = √1800 = 42.43 ft
which is longer than the banner.
Blueprint question:
No, diagonal of square C is 70.71ft

Select all the statements that would be true in a probability model for rolling a cube with faces numbered 1 through 6.
Sample space: 1, 2, 3, 4, 5, 6
P(1) = 16
P(2) = 26
P(6) = 16
The outcomes of the trial: 2, 2, 2, 5, 3, 2, 6, 5, 6, 1
Answer: A,B, D and E.
Step-by-step explanation:
When a cube with faces numbered 1 through 6 is rolled:
(A)The sample space is 1,2,3,4,5,6. Option A is correct
(B) P(rolling a 1) =1/6, Option B is correct
(C)P(rolling a 2)=1/6, therefore option C is incorrect.
(D)P(rolling a 6)=1/6, Option D is correct
(E)In an experimental trial, the outcome must be members of the sample space. Therefore, the outcomes in option (E), 2, 2, 2, 5, 3, 2, 6, 5, 6, 1 are valid.

Can someone please explain composite events to me in layman's terms?
Step-by-step explanation:
A simple event is one that can only happen in one way - in other words, it has a single outcome. If we consider our previous example of tossing a coin: we get one outcome that is a head or a tail. A compound event is more complex than a simple event, as it involves the probability of more than one outcome.
