Step-by-step explanation:
Since sin (arccos x) = 1,
x = cos(arcsin 1)
= cos(π/2)
= 0.
Hence x = 0.
If Rhonda has 140 points, you would want to subtract 30 from her score to get 110 and then divide by two to get mark’s score. Your final answer would be 55
Answer:
10a = 30
Step-by-step explanation:
By using elimination:
4a + 2z = 10
-2(3a + z) = -2(-10)
4a + 2z = 10
6a - 2z = 20
2z and -2z cancel out
10a = 30
a = 3
They are asking for 10a, so 10 (3) = 30.
