A) you must plug in 50 for variable F and solve for C
C=

(50-32)
C=

(18)
C= 10
50 degrees fahrenheit is equal to
10 degrees celsius B) you must solve the equation for F
C=

(F-32)
C/

=F-32
C/

+32=F
F= C/

+32
dividing by a fraction is the same as multiplying buy its reciprocal so it can also be written as
F=
C +32
now you just plug in 50 for the variable C in the new equation
F=

(50) +32
F= 90 + 32
F= 122
50 degrees celsius is equal to
122 degrees fahrenheit

Answer:
A. 45°
Step-by-step explanation:
When we are given two measurements of interior angles we add both of those angles together.
Also know that a triangle equals 180 degrees
So when we write out this expression

Answer:
35
Step-by-step explanation:
Here we see 5 black keys for every 7 white keys.
So the ratio is 5:7
If we need 49 white keys, find the amount we scale the original ratio by:
49/7 = 7
So we are scaling by a factor of 7.
The number of black keys would be 5 * the scale of 7. = 35
So there should be 35 black keys.
Answer:
Step-by-step explanation:
-6 is to the left from origin and π/12 is in between 0 and π/6 above the x-axis. So the point (-6, π/12) is in the second quadrant.
<u>Other points represent coordinates of:</u>
- A=(6, π/12), C=(-6, -π/12), D=(6, -π/12)
This is point B and correct choice is option B.
