We are given
Firstly, we simplify left side
Left side is
we will make all x terms together
and y terms together
we can multiply left side by using exponent rule
now, we can set them equal
Since, both sides have x,y and 8
and both are equal
so, their exponent must be equal
so, exponent of y must also be equal
we get

Answer:
148 minutes = 2h 28 min
Step-by-step explanation:
48min+(25+75mins)=48+100=148
C. The 2 in the denominator turns into -2 and you just take the coefficients directly from the numerator.
Y-9 + y/2 = 180
Add nine to each side
y+y/2=189
Multiply each side by two
2y+y=378
Add the y's together
3y=378
Divide it all by three
y=126
so, Angle B is 126 degrees
I hope that helps!
