15 + 55 + 40 + 39 + 68 = 217
Perfect squares between 260 and 320...
17 is the perfect square of 289 which is between 260 and 320
289 - 217 = 72
72 is the missing number.
Answer:
x/6 = 3/9
9x = 18
x = 2
Answer: 2:6 as 3:9
If x:6 as 3:9, then x is equal to
---
Equation:
(x/6) = 3/9
x = 6(3/9)
Step-by-step explanation:
Answer:
BC = 50
Step-by-step explanation:
I believe what I'm doing is correct but to be completely honest with you, I haven't done this in a while lol
Okay so...
You would do
1. 6y-16 = 4y+6
You would subtract 4 from 6...
2. 2y-16 = 6
You would then add 16 to 6...
3. 2y = 22
Then, divide 2 from 22...
4. y = 11
Substitute into BC...
5. 6 (11) - 16 = 66 - 16 = 50
Then, you get your final answer...
6. BC = 50
I hope it's right. Good luck ^^
Answer:
x = 2.
y = 6.
Step-by-step explanation:
Consider the triangle on the left.
Because there are 2 equal angles at the vertex on the bottom right:
3/9 = x/(8 - x)
1/3 = x / (8 - x)
3x = 8 - x
4x = 8
x = 2 (answer).
Similarly, for the second triangle:
3/y = 2/4
3/y = 1/2
y = 6
(answer).
What are the options for answers?
