Step-by-step explanation:
Answer:
4/12
Step-by-step explanation:
Answer:
x=18
Step-by-step explanation:
So (3x+20)° and (5x-16)° are angles that are vertically opposite to each other; which means that they are equal to one another. Which means we can say:
(3x+20)=(5x-16)
20+16=5x-3x
36=2x
x=18
*and the two angles are 74°
Answer:
Karen
Step-by-step explanation:
Since neither 3/8 or 2/5 can be simplified further, you need to multiply them by the LCM to get the same denominator.
The LCM of 5 and 8 is 40.
Multiply 3/8 by 5 ( both numerator and denominator)(turns into 15/40 )
Multiply 2/5 by 8 ( both numerator and denominator)(turns into 16/40)
Now that they have the same denominator, we can see which one is closest to a whole mile.
16/40 is greater than 15/40, so Karen rode farther.
Yea you multiply it 1 plus 2 times 9 and get 52
