Angle 1 is a "corresponding angle" with respect to the one marked 155°, so it has the same measure. The measure of angle 1 is ...
... 155°
7 is the most common in this expression.
therefore to factorise, you will choose the most common factor.
the answer will be -7(r+5x)
B. is 12 degrees Farenheit because you just have to convert it, so if you count the lines inbetween 10 and 20 its 4 so it goes by 10,12,14,18,20 then you connect the 10 degrees celcius to the line on farenheit and it matches 12 degrees so thats the answer
First rearrange as:

Taking logs of both sides, we get:


x = 6.26.
Answer:
opening the brackets we have;
3t+15+5t+15=-4t-12
collect like terms
3t+5t+15+15=-4t-12
8t+30=-4t-12
8t-4t=-12+30
4t=18
t=18/4
