Answer:
x = 28
Step-by-step explanation:
1) Add 21 to both sides of the equation.
-4x - 21 + 21 = 91 + 21
2) Simplify
A. Add the numbers
-4x = 91 + 21
B. Add the numbers
-4x = 112
3) Divide both sides of the equation by the same term.
-4x/4 = 112/-4
4) Simplify
A. Cancel terms that are in both the numerator and denominator
x = 112/-4
B. Divide the numbers
x = 28
Add
21
to both sides of the equation
−4 −21 = 91
−4 −21 + 21 =91+21
Then it will be = −28

50 secs
as $90÷5hrs= 18 $ per hrs
$18÷60min=$0.30 per min
$0.30÷60sec=$0.005 per sec
$0.25÷$0.005= 50sec to make $0.25
so 50sec is the answer
we are given
(x,y)=(5,-12)
so, x=5 and y=-12
now, we can find r
now, we can find cos
so, we get
