Answer:
The solution is w=8
Step-by-step explanation:
we have
-2w+4=-12
Solve for w
That means -----> isolate the variable w
Subtract 4 both sides
-2w+4-4=-12-4
-2w=-16
Divide by -2 both sides
-2w/-2=-16/-2
w=8

Answer:
Let's define the high temperature as T.
We know that:
"four times T, was more than 2*T plus 66°C"
(i assume that the temperature is in °C)
We can write this inequality as:
4*T > 2*T + 66°C
Now we just need to solve this for T.
subtracting 2*T in both sides, we get:
4*T - 2*T > 2*T + 66°C - 2*T
2*T > 66°C
Now we can divide both sides by 2:
2*T/2 > 66°C/2
T > 33°C
So T was larger than 33°C
Notice that T = 33°C is not a solution of the inequality, then we should use the symbol ( for the set notation.
Then the range of possible temperatures is:
(33°C, ...)
Where we do not have an upper limit, so we could write this as:
(33°C, ∞°C)
(ignoring the fact that ∞°C is something impossible because it means infinite energy, but for the given problem it works)
Answer:
Step-by-step explanation:
Each rotation is 360° or 2π radians. So, 36.7 rotations is ...
36.7×360° = 13,212°
or
36.7×2π = 73.4π radians
Answer:
55.2° ≤ c ≤ 55.8°
Step-by-step explanation:
We know a + b + c = 180
Let's take the smallest value of a and b and find largest value of c:
51.3 + 72.9 + c = 180
c = 55.8
Now,
Let's take the largest value of a and b and find smallest value of c:
51.5 + 73.3 + c = 180
c = 55.2
Thus, we can say, range of c is:
55.2° ≤ c ≤ 55.8°
