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).
Answer:
correct choice is 1st option
Step-by-step explanation:
Two given triangles have two pairs of congruent sides: one pair of length 7 units and second pair of length 8 units. The third side is common, i.e the lengths of third sides are equal too.
Use SSS theorem that states that if three sides of one triangle are congruent to three sides of another triangle, then these two triangles are congruent.
Thus, given triangles are congruent by SSS theorem.
