Answer:
23:2 is 25
![100 \div 25 = 4](https://tex.z-dn.net/?f=100%20%5Cdiv%2025%20%3D%204)
![23 \times 4 = 92](https://tex.z-dn.net/?f=23%20%5Ctimes%204%20%3D%2092)
![2 \times 4 = 8](https://tex.z-dn.net/?f=2%20%5Ctimes%204%20%3D%208)
Check the answer
![92 + 8 = 100](https://tex.z-dn.net/?f=92%20%2B%208%20%3D%20100)
![therefore \: copper = 92g \: \\ and \: tin = 8g](https://tex.z-dn.net/?f=therefore%20%5C%3A%20copper%20%3D%2092g%20%5C%3A%20%20%5C%5C%20and%20%5C%3A%20tin%20%3D%208g)
Step-by-step explanation:
At least I think that's how you do it
Answer:
The two angles are 10 degrees and 170 degrees.
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
Let the angle be called "x", and the supplementary angle be called "180-x"
Converting words to math: x-160=180-x
Add x to both sides: 2x-160=180
Simplify: 2x=20
Divide by 2: x=10
Let me know if this helps!
16. 9
Since each side are congruent, you set the two sides to each other
7x-12=3x
Subtract 7x from both sides
-12=-4x
Divide -4 from both sides
3=x
3+3+3=9
18. 28
2x-3=3x-10
Add 10 on both sides
2x+7=3x
Subtract 2x on both sides
7=x
7+7+7+7=28
