First Answer:
x = 12
First Step-by-step explanation:
12 + x = -3(4 - x)
12 + x = -12 + 3x
- x - x
—————————
12 = -12 + 2x
+ 12 + 12
—————————
24 = 2x
24/2 = 2x/2
12 = x
Second Answer:
No solution
Second Step-by-step explanation:
2(x - 1/2) = 8 + 2x
2x - 1 = 8 + 2x
+1 +1
—————————
2x = 9 + 2x
- 2x - 2x
—————————
0 = 9
^^ No solution
Answer:

Step-by-step explanation:
To calculate the scale factor k, find the ratio of corresponding sides
= 
= 6
= 
= 6
Hence the scale factor k = 6 → A
Answer:
For this you need to see where you can find graphs, data, and charts in your life. You can create a chart for things you notice in recent weather, bird behaviors, etc. If I gave you an entire answer, it might not line up with where you are. Example: If I took notes and created a chart for how often it rained and said that it rained every other day throughout the week, it may not line up from where you are.
Step-by-step explanation:
I wish you the best of luck on your assignment!
Let's say a = number of ordered soups, b = number of ordered sandwiches.
Then 4.5a + 7.75b = 113.50, and a and b are integers between 0 and 18 inclusive.
How do we tackle this? If all ordered soup, the cost would be $81, so we'll have at least 4 sandwiches. If all ordered sandwich, the cost would be $139.5, so at most 15 sandwiches were ordered. You also know an even number of sandwiches was ordered, to let the price end at 50 cent.
If you brute-force from 4,6,8,10,12 to 14 sandwiches, you find the answer at 10 sandwiches and 8 soups.
10*7.75 + 8*4.50 = 113.50
