12=w−|−7| help me on this
2 answers:
Answer:
Value of w is:
19
Step-by-step explanation:
We are given a equation:
12=w−|−7|
Modulus(|a|) gives us the absolute value of that number
i.e. if a is a positive number then, |a|=a
and if a is a negative number then |a|= -a
-7 is a negtaive number
so, |-7|= -(-7)=7
So, equation 12=w−|−7| is converted to
12= w-7
Adding 7 on both sides, we get
w= 19
Hence, Value of w is:
19
We first take the absolute value of -7, making 7. This simplifies the equation to 12=w-7. Adding 7 to both sides finds us w=19.

The x value is negative (second quadrant). 13 is the hypotenuse. So the missing side is 13^2 = (-12)^2 + y^2.
Sin theta is the opposite (5) over hypotenuse (13).

Answer: 34767.2
Step-by-step explanation:
given p = $16,000, n = 14 years, y = 5.7%
amount in bank after 14 years = p ( 1 + </100)
= 16,000 (1 + 5.7/ 100) 14
= 34767.2
