Answer:
The root of 16 is 4 and the root of 9 is 3.
Step-by-step explanation:
For the first instance, 16+9 is 25 and the root of that is 5. But for the second one, we have to first find the roots. So 4+3 which equals 7. These are obviously not equal. Does this make sense? Hope that helps.
well -2(-1/4) is .5
so -2, .5,(multiply each by -1/4)
-2, 0.5, -0.125, 0.03125
Answer:
Step-by-step explanation:
probability of choosing a boy = 12 / 28 = 3 / 7
in % = 3 / 7 x 100 = 42,86%
probability of choosing an a student = (4 + 10) / 28 = 14 / 28 = 1 / 2
in % = 1 / 2 x 100 = 50%
ANSWER

EXPLANATION
The given expression is

To find an expression for d in terms of a, b, and c, means we want to make d the subject of the relation.
This means that, we need to isolate d on one side of the equation while all other terms are on the other side.
We subtract from both sides of the equation to obtain,

We now divide through by -1, to get,

Or

The topic is change of subject
