2/20 = 1/10 = 3/30 = 4/40
so 3 equivalent ratios can be 1/10 (or 1:10), 3/30 (or 3:30), 4/40 (or 4:40)
Writing this statement symbolically, we get:
n
--- - 5 = 8
2
Adding 5 to both sides, we get n/2 = 13. Then n = 26.
U should use friendly numbers when subtracting.......the numbers have to be between 3 and 10
Answer:
B) Ill only
Step-by-step explanation:
This is because y = arcsin x can be re-written as sin y = x, We then differentiate sin y = x implicitly with respect to z to obtain
d(siny)/dz = dx/dz
(cosy)dy/dz = dx/dz
dy/dz = (1/cosy)dx/dz
14.2 - 2.2 - 1
12 -1
11
Hope this helps
