Answer:
x = 4
Step-by-step explanation:
Sum of angles (in degrees) in a triangle = 180
so
60 + 70 + 12x + 2 = 180
Add like terms
132 + 12x = 180
subtract 132 from both sides
12x = 48
divide both sides by 12
x = 4
Answer:
8 represents the temperature at the mid night of Friday was 8°.
Step-by-step explanation:
The weather service measures the temperature, T, every hour, h, beginning at midnight of each 24-hour period.
If on Friday, the temperature was modeled by T = 43h + 8.
That means at h =0 i.e. at the midnight the temperature T is given by 8.
So, 8 represents the temperature at the midnight of Friday was 8°. (Answer)
The answer to this question is 7 4/9
to find this you first have to find the LCM (in this case it is 9) then you have to figure what you multiplied by to get to your LCM (9) whatever you do to the bottom you have to do to the top and that is how you end up with your numerator (the top number in a fraction) usually if you have the same denominators (the bottom number in a fraction) you can +/- like normal. sometimes though you can't (like this case) because you can't take a bigger number away from a smaller one.
