-5+2= -3
So the value of (-5) +10-8+63 is 60
Answer:
-9.5-42.1/6=x
-8.6
-9.5+ 6x-8.5
-61.1
Step-by-step explanation:
I'm assuming your allowed to use a calculator for this? That's what I would do.

To go about the fraction, take the whole number and times it by the denominator, then add in the numerator to create a new fraction(a whole one not mixed). Then simply divide the numerator by the denominator.


193 is the new numerator and the new whole fraction is this and dividing it out gives you,

For the third one, just input it into a calculator,
Answer:
find derivative of function
sub in x value of point to find gradient of tangent
put gradient into y=(gradient)x+c
Sub in point and solve for c
you have found the equation of the tangent.
