Step-by-step explanation:
In this question we have to find the expression for the value of temperature in terms of degrees Celsius.
Since, the given expression is,
F = 1.8C + 32
F - 32 = 1.8C + 32 - 32
F - 32 = 1.8C
For F = C,
C - 32 = 1.8C
C - 1.8C = 32
-0.8C = 32
C =
C = -40
Therefore, at (-40°C) degrees of temperature degrees Fahrenheit and degrees Celsius are equal.
Answer:
-125
Step-by-step explanation:
Each term is 7 less than the previous term.
1st term: 15
2nd term: 15 - 7
3rd term: 15 - 7 - 7 = 15 - 2(7)
4th term = 15 - 7 - 7 - 7 = 15 - 3(7)
Notice that each term is 15 minus a multiple of 7. The multiple is obtained by multiplying 7 by 1 less than the term number.
The formula is:
For the 21st term, multiply 7 by 20, and subtract from 15.
7 × 20 = 140
15 - 140 = -125
Using the formula:
Answer: -125
