The number is 2 :) because you need common denominators therefore you multiply by 3 so that 4 becomes 14 therefore 3 times 2 is 6 and 11 menus 6 is 4 so you get 4/14
Answer:
x = 42-degrees
Step-by-step explanation:
x + 48 = 90 --> *subtract 48 from both sides*
x = 42
Is it a b c or d because I can give you an estimate
We may determine the degree of a polynomial by observing the number of times it has intersected the x-axis
Above in the picture we can tell that it has intersection coordinates of
((-2,0) (-1,0) (1,0)(2,0)
Therefore we have a 4th-degree polynomial (which makes it even degree)
And since both of his sides are going infinitely upwards then the leading coefficient is positive.
Hope i helped.
let
d1 = 250 mi the distance that Mattie Evans drove
v1 = the speed of Mattie Evans
d2 = 1300 mi the distance the plane traveled
v2 = the speed of the plane
The speed of the plane was 190 mph faster than the speed of the car:
v2 = v1 + 190
since time = distance/speed and they both traveled the same time we have
d1/v1 = d2/v2
250/v1 = 1300/v2 cross multiply
250v2 = 1300v1 divid eboth sides by 50
5v2 = 26v1
by solving the system of equations:
v2 = v1 + 190
5v2 = 26v1
we find
v1 = 45.24 mph
v2 = 235.24 mph
