Answer:
so it would be (7x-4)+(5x+8) = 160
x=13
If the value is 5 and the equation is
I = 48t
then
I = 48*5 = 240
option B
B) 52.5°
Bisect means in half and half of 105° is 52.5°
You divide by 5/13. Remember when dividing fractions you multiply by the reciprocal. 5/13 cancels on the left side, leaving t.
So here you have -9/(5/13), but we can put -9 as -9/1, then instead of dividing by 5/13, multiply by 13/5: 117/5. This evens out, when divided, to t=23.4
