Answer:
it is 6/7, you can simplify that fraction by dividing with 7
In order to find the amount left after both sisters ate the cereal, we have to add the amount of cereal the two sisters ate.
Katrina ate 1 3/4 and her sister ate 7/8.
(1 3/4 + 7/8)
(you put a parentheses around it so that you add the two first before subtracting it from the original amount)
Then, we would subtract it from the original amount: 12 1/2.
-> The equation would be: 12 1/2 - (1 3/4 - 7/8).
<u>Answer:</u>
A) Scalene E) Obtuse
<u>Detailed Explanation:</u>
A) Scalene
This triangle would be classified as scalene because none of the angles are equal.
____________________________________________________________
E) Obtuse
This triangle would be classified as an scalene triangle because one of the angles is larger than 90 degrees.
2/7x - 2/5x = 8
multiply both sides by 35
= 10x - 14x = 280
combine 10x and 14x
= -4x = 280
divide both sides by -4
x= -70
You would need to remove (-2, 1)
