Given the equation 6x + 18 = 72:
Part A: Write a short word problem about a purchase made to illustrate the equation. (6 points)
Part B: Solve the equation showing all work. (4 points)
Answer:
Part A: You are buying candy bars online. They cost $6 each and there is an $18 shipping fee. You have $72 to spend. How many candy bars can you get?
Part B: x=9
Step-by-step explanation:
6x + 18= 72
You want to get x alone:
Subtract 18 from both sides
Rewrite:
6x= 72-18
Now, subtract 72-18
Rewrite:
6x= 54
Divide 6 from both sides
So, that would be 54/6
Answer: x=9

x3+y3+z3=k whats the k (in numbers) for 55
Answer:
Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100.
On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42? … I hope it helps you

⇒ ∠1 and ∠2 are angles lying on a straight line.
⇒This simply means that the sum of ∠1 and ∠2 since the straight line forms an angle of 180°
∠1+∠2=180°
⇒It is given that the measure of ∠2 is 60° more than ∠1
This means that to get ∠2 you have to add 60° in ∠1
As a conclusion we can say that ∠2=∠1+60°...(second equation to get ∠2)
⇒In the equation ∠1 +∠2=180°
⇒Substitute the value of ∠2 which is (∠1+60°)
∠1+(∠1+60°)=180°
⇒Now simplify to get the value of∠1
∠1+∠1=180°-60°
2(∠1)=120°
Note I got 2(∠1) since ∠1+∠1= 2× (∠1)
[tex]2( < 1)=120\\\frac{2( < 1)}{2} =\frac{120}{2} \\ < 1=60[/tex]
∠1 =60°
⇒Note from what we have now we can also get the value of∠2 but we were not asked to get it. Therefore we will not.

1. What is a formula that can be used to find the area of one triangular section of the door?
2. How do you know the formula will work?
Answer:
[tex]A=\frac{ab}{2}[/tex] or [tex]A = a *\sqrt{c^2-a^2} /2[/tex]
Step-by-step explanation:
Depending on the values you take depends on the equation you would use to solve for the area of a right triangle(the first answer accounts for measuring both arms(the sides connected to the 90 degree angle(a and b)), where as the second answer accounts for using the hypotenuse and one of the arms). That means that a 90 degree angle is involved, or as illustrated here, the square in the bottom right corner. If this were a non-right angle triangle, a different formula utilizing the height of the triangle would be used instead.
[tex]A = \frac{h_{b}+b}{2}[/tex]
Since the right angle exists, a height is already given using one of the arms of the triangle in its place. We can also confirm it is a triangle by adding up all degrees of the triangle, in which it would equal 180 degrees confirming it is indeed a triangle as well.
By using trigonometric relations we will see that the area is:
How to find the area of one triangular section?
Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.
Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).
h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:
tan(60°) = x/h
x = tan(60°)*h
Then our two catheti are h and tan(60°)*h.
This means that the area will be:
Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

Suppose a certain breed of dog loses about 75 hairs per day. What integer represent this change in the amount of hair per week write a mathematical argument that can be used to defend your solution
Answer:
75 hairs/ day = 525 hairs / week
Step-by-step explanation:
so your base question for this is 75 hairs/ day =? h/ week. how? if the dog is losing 75 hairs per day, then you would do 75 x 7 becuase there are 7 days in a week. the answer to that would give you how many hairs the dog was losing per week. (see attached image for reference)

(REPLY FOR EXTRA POINTS) School hack:
If you have a question something like this: "Determine which integer makes the inequality 6(n − 5) < 3(n + 4) true."
The answer would most likely be the last answer choice.
This is because when teachers create the question they put it as the last one to make you work out all of the firsts ones first so you can do more work which means more practice.
I'm not 100% sure, but I had a question like this and the answer was the last one.
Hope this school hack helps!! :)

Step-by-step explanation:
Selena and Luis are building a model bridge out of balsa wood. To make a strong bridge, they create each post by laying out two long wooden poles horizontally, as shown in the diagram, and connecting them with smaller strips of balsa wood laid diagonally in a triangle pattern. The triangle pattern is continued down the entire length of the wooden poles.
The poles are 12 centimeters apart, and each small strip of balsa wood is 13 centimeters long.
If the two poles are each 100 centimeters long, how many small strips of balsa wood will they need to connect them?

3. 6/8
4. 2 badges
Step-by-step explanation: for number 4
Mr.Garcia is making badges. Each badge has 3/8 yards of ribbon. He starts with 3/4 yard of ribbon. We need to find how many badges he can make. The length of each badge is 3/8 yard of ribbon. The total length of the ribbon is 3/4 yard. To find the number of the badges is the quotient of the division of the total length of the ribbon by the length of each badge. The number of badges = the length of the ribbon ÷ the length of the badge. The number of badges = 3/4 ÷ 3/8. To solve the division of two fraction we change the division sign by the multiplication sign and reciprocal the fraction after the division sign. The number of the badges = 3/4 × 8/3. The number of the badges = 3*8/4*3=24/12=2. So he can make 2 badges
