Answer:
Step-by-step explanation:
Since the ratio is 4x:4x:7x, if we add all those numbers up we get 15. Then we do 75/15 to get what x equals. So we get 5. So x equals 5. Following the rules of multiplication, you do 4(5):4(5):7(5), and simplifying that further, you get 20:20:35. If we add all those values up, we should get 75, and we do!
If you're wondering why I did 4x:4x:7x instead of 4:4:7, it's because a ratio is just a...well ratio? It's easier to visualize if you put a variable because the variable could be anything, and you would have to multiply all the given values to get the same proportions. In summery, I did it so it was easier to visualize
Answer:
it's -8/5 because you subtract y2 from y1 and x2 from x1
Step-by-step explanation:
Answer:
y= 1/4
Step-by-step explanation:
Triangle? because when you rotate it each part will be a bit different
Eithet 330x4 or 330 divide 4 so it is either= 1320 or 82.5 hope this helps
