Answer:
The 20 mph headwind slows the plane down. This is because the headwind comes at the head of the plane and goes in the opposite direction of the plane.
So the plane's actual speed (with the wind included) is 550-20 = 530 mph.
Answer:
C
Step-by-step explanation:
y=5x reads "y equals (5 times x)", which we can rephrase to "the value of y is 5 times the value of x"
y=x+5 reads "y equals (x plus 5)", which we can rephrase to "the value of y is 5 more than the value of x".
Ergo, answer C is what we're looking for.
M<A + m<B = 180
5y + 9y + 68 = 180
14y + 68 = 180
14y = 180 -68
14y = 112
y = 112/14
y = 8
so
m<B = 9y + 68
m<B = 9(8) + 68
m<B = 72 + 68
m<B = 140
6 outcomes are possible if i am correct !
