Problem 7
This triangle is an equilateral triangle. All sides are the same length (some unknown number which we don't care about). All angles are the same measure each 60 degrees. Set this expression equal to 60 and solve for x
25x - 15 = 60
25x - 15+15 = 60+15 ... add 15 to both sides
25x = 75
25x/25 = 75/25 .... divide both sides by 25
x = 3 which is the answer we want

Problem 8
For this problem, I've decided to break up the work into separate image files to show how I did the steps. Otherwise, it might be really cluttered to have everything typed here on the same page.
To get the coordinates of point E, check out the image labeled "figure 1". For point G, look at "figure 2".
For proof that EG is parallel to BC, look at "figure 3"
For proof that segment EG is half the length of segment BC, look at "figure 4"
Finally, I've drawn on the diagram to visually show what it all looks like as a summary in "figure 5"
To complete the table we must carefully observe the keypad, we will notice that each number is equivalent to 3 letters of the alphabet except the numbers 7 and 9 which have 4 letters each.
<h3>How does the keypad work?</h3>
Previously, cell phone keypad had a different layout than today. The numbers were related to the letters of the alphabet and the number key was pressed according to the letters that were related.
For example, if you wanted to type the letter B, you would have to press the number 2 key twice.
The relationship of numbers and letters was distributed as follows:
- It had no letters.
- A, B and C.
- D, E and F.
- G, H and I.
- J, K and L.
- M, N and O.
- P, Q, R and S.
- T, U and V.
- W, X, Y, and Z.
According to the above, the table would be completed as follows.
Note: This question is incomplete because there is some missing information. Here is the missing information:
1. Complete this table to show the relation from letter to number.

Answer:
Step-by-step explanation:
subtract it
Answer:
65.63%
Step-by-step explanation:
21: 32*100 =
(21*100): 32 =
2100: 32 = 65.63
576+52=
628
So, the restaurant sold 628 meals in all.
