Answer:
7/9 son azules. hay 27 en total y hay 6 lapices de blanco
Step-by-step explanation:
Let p and m represent the numbers of miles in the plains and mountains, respectively.
.. p + m = 300 . . . . . . . the whole trip was 300 miles
time = distance/speed, so the trip time can be written as
.. p/90 + m/37.5 = 3 48/60
.. 5p + 12m = 1710 . . . . . . . . . . multiply by 450 to put in standard form
You can solve these two equations by any of several means. The variable p can be eliminated by subtracting 5 times the first from the second.
.. (5p +12m) -5(p +m) = 1710 -5*300
.. 7m = 210
.. m = 30
30 miles of the trip was through the mountains.
Answer:
Step-by-step explanation:
- (y+9) = 10
Multiply through by -1 gives us
y+9 = -10
Subtract 9 from both sides
y = -19
That's your answer.
If you work it through it satisfies the equation.
That is:
- (-19 +9) = 10
-(-10) = 10
10 = 10
Boo ya!
