Answer:
A=84°
B=28°
C=68°
Step-by-step explanation:
We know the following:
A=3B --> "angle A is three times as large as angle B"
A=C+16 --> "and also 16 degrees larger than angle C"
We can find ∠C by subtracting 16 from both sides from the above statement:
C=A-16
We know that in a triangle there are 180°, therefore we can write the following equation.
A+B+C=180°
1) Substitute 3B as A in the above equation:
3B+B+C=180°
2) Substitute A-16 as C in the above equation:
3B+B+A-16=180°
3) Substitute 3B as A in the above equation:
3B+B+3B-16=180°
4) Combine alike terms:
7B-16=180
5) Add 16 to both sides:
7B=196
6) Divide both sides by 7:
B=28°
Now, lets plug in 28° as B in the first equation we deduced:
A=3B --> A=3(28)
A=84°
Now, lets plug in 84° as A in the second equation we deduced:
A=C+16 --> 84=C+16
C=68°
Answer:
It would be
-2+7x
Step-by-step explanation:
Function of a function is the interior function which is responsible for the output of the exterior functions. The value of the function is 68.
<h3>What is the function of a function?</h3>
Function of a function is the interior function which is responsible for the output of the exterior functions.
Given information-
The given equations in the problem are,
The value of has to be find out.
First find the interior function,
Hence the value of the interior function at equals to -2 is,
Now The value of is,
Hence put the values of -6 in the first function,
Hence the value of the function is 68.

Answer:
Step-by-step explanation:
Let the x be the number of hours after noon.
<u>We have the following equation:</u>
- 14.83 + 0.12(x + 3) = 15.33 - 0.15x
- 14.83 + 0.12x + 0.36 = 15.33 - 0.15x
- 0.12x + 0.15x = 15.33 - 15.19
- 0.27x = 0.14
- x = 0.14/0.27
- x ≈ 0.5
