Answer:
arc of WXY= 224°
Step-by-step explanation:
measure of angle C is half of the WXY arc

Answer:
x +3 = x^2 +2x -4
Step-by-step explanation:
Straight substitution of the top expression for y gives you ...
x +3 = x^2 +2x -4
__
This lets you rewrite the equation to standard form as ...
x^2 +x -7 = 0
and find the solutions to be ...
x = (-1±√29)/2
Corresponding y-values will be 3 more than this:
y = (5±√29)/2
Answer:
Step-by-step explanation:
Find the next three terms: 9,4,-,1,-6,-11,<u>-16....</u>
This is arithmetic progression.
d = 4 - 9 = -5
-11 - 5 = -16
2) You know that........
The other integer is greater than 5 and the sign of the other number is + (positive sign)
Eg: (-5)+ 11 = 6
3) Cost of one gallon = 46.20/12 = $ 3.85
