Answer:
C. 6.2 inches
Step-by-step explanation:
There are many ways to do this but I like to cross the miles out by putting it on the denominator
927 miles * 1 inch/150 miles = 6.18
Rounded is 6.2
Step-by-step explanation:
left side of the expression has an x^2 term, x term and constant(x^0 term), same for the right side of the expression
x^2 coefficient = p(-5) + 4(-3qx) = -5p -12qx
(1)
since both equations express y in terms of x, equate the right sides
- 2x = - 4x + 10 ( subtract 4x from both sides )
2x = 10 ( divide both sides by 2 )
x = 5
substitute x = 5 into y = - 2x → y = - 10
solution is : (x, y ) → (5, - 10 )
(2)
equate the right sides of both equations
3x = 2x - 7 ( subtract 2x from both sides )
x = - 7
substitute x = - 7 into y = 3x → y = - 21
solution is : (x, y) → (- 7, - 21)
(3)
substitute y = - 8 into the other equation
- 8 = 6x + 22 ( subtract 22 from both sides )
- 30 = 6x ( divide both sides by 6 )
x = - 5
solution is : (x, y ) → (- 5, - 8 )
I would say 244.8 minutes but I've been wrong before.
Use pythagora's theorem to solve it
c^2=a^2+b^2
x^2=(3/4)^2+1^2
x^2=25/16
x= 5/4 = 1 1/4 inch
therefore it is B
