Answer:
T4 = -2°F
Step-by-step explanation:
Given the following data;
Current temperature = 10°F
Constant, K = 3°F
Time, t = 4 hours
In four (4) hours, we have;
T = kt
Substituting into the equation, we have;
T = 3 * 4
T = 12°F
T4 = current temp - new temp
T4 = 10°F - 12°F
T4 = -2°F
Therefore, the temperature it will be in 4 hours is - 2°F.
To solve this, it is easiest to find the least common multiple of the denominators which is 24. Now we can rewrite our fractions.

X = 20
This is an isosceles triangle so third angle is also 2x because of symmetry.
Angle sum = 5x + 2x + 2x = 9x = 180 degrees
First, you solve for this algebraically, where you solve for x. Then, you can graph the solution. By doing this, you shade all of the possible values for x while you put an open or closed circle for the value of x.
