Answer:
A
Step-by-step explanation:
correct on edge
Let share of A is 3x and B is 2x
According to question
3x + 2x = 85
x = 85/5
x = 17
Therefore A pays 51 euros
Answer:
The difference in meaning is that
-3 is a signed value. It lies to the left of zero
+3 is also a signed value, and since it is positive, it lies to the right of zero
|-3| is just the physical distance (left or right) of -3 from zero. Since we live in a physical world, all distances are positive, so its signed value is 3.
Since +3 is also 3 units from zero, |+3| = 3
|-3| = |+3| = 3 since both are three units away from zero.
So, when using absolute values as numbers, rather than distances,
|x| = x if x is not negative
|x| = -x if x is negative
Step-by-step explanation:
tan 30°= root 3/ 3
r²=x² + y²
r²= 4root3 ² + 12²
r²= 48 +144
r²= 192
ŕ= 8root3
so the bottom is 12...
the other side is 4root3
and hypotenuse is 8root3
