Jan,Mya, and sara ran a total of 64 miles last week. Jan and Mya ran the same number of miles. Sarah ran 8 less miles than Maya. How many miles did Sarah run?
Answers
Jan, Maya and Sarah run a total of 64 miles per week How many miles did Sarah run if she ran less than 8 miles compare to Maya and Jan Jan and Maya = x Sarah = x Total miles = 64
=> 64 = x + x + x-8 => 64 = 3x – 8 => 72 = 3x => x = 24 Since Jan and Maya ran the same miles, they ran 24 miles each Since Sarah is 8 less than Maya’s and Jan’s ran each => x – 8 => 24 -8 => 16 Sarah ran 16 miles in a week.
How do I simplify:
-4x + 4x* ______ -32x+32

-x/8 you take -4x out as a factor of the numerator and 32 out as a factor of the bottom line. Then cancel the (1-x)'s and youre left with -4x/32. Then divide both top and bottom by 4 = -x/8
