Answer:
The formula to calculate the Celsius temperature for a given Fahrenheit temperature is:

Step-by-step explanation:
Given formula:

where
represents temperature in Fahrenheit and
represents temperature in Celsius.
To solve the equation for
.
Solution:
We have,

Subtracting both sides by 32.


Dividing both side by 1.8


∴ 
Using the above formula, we can calculate the Celsius temperature for a given Fahrenheit temperature.
Answer:
B
Step-by-step explanation:
180-130=50
180-50=130
130:2=65
Answer:
= 5n
Step-by-step explanation:
There is a common difference d between consecutive terms
d = 10 - 5 = 15 - 10 = 20 - 15 = 25 - 20 = 30 - 25 = 5
This indicates the sequence is arithmetic with explicit formula
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 5 and d = 5 , then
= 5 + 5(n - 1) = 5 + 5n - 5 = 5n
Using the definition of vertical angles, the value of z is: 15.
<h3>Vertical Angles Pair</h3>
The two pairs of opposite angles formed when two straight lines intersect are called vertical angles, and are therefore congruent to each other.
Thus:
2z + 10 = 40
2z = 40 - 10
2z = 30
z = 30/2
z = 15
Therefore, using the definition of vertical angles, the value of z is: 15.
