Answer:
2/3y
Step-by-step explanation:
If the class usually has y students and has 2/3 today, it can be represented by 2/3y.
Since multiplying a number or variable by 2/3 makes it 2/3 of the amount, 2/3y will represent the people in the class.
So, in terms of y, 2/3y represents the number of students in class today.
Answer:
B(-6, 0)
Step-by-step explanation:
You want to find B such that ...
(B -A) = (3/4)(C -A) . . . . the required distance relation
4(B -A) = 3(C -A) . . . . . . multiply by 4
4B = 3C +A . . . . . . . . . . add 4A, simplify
Now, we can solve for B and substitute the given coordinates:
B = (3C +A)/4 = (3(-6, -2) +(-6, 6))/4 = (-24, 0)/4 = (-6, 0)
The coordinates of point B are (-6, 0).
Each person will get 1.6 parts of the cookies or 1 3/5 cookie.
You do 8/5=1.6
Answer: D: Corresponding parts of congruent triangles are congruent
Step-by-step explanation:
If two triangle are congruent using postulate of theorems of congruence then their corresponding parts are congruent by CPCTC rule.
The CPCTC rule says that if two triangles are congruent then their each corresponding part whether angles or sides must be equal.
Here if triangle abc= def by side-side-side triangle congruence theorem,
then b=e [which is a corresponding part of both triangles] by Corresponding parts of congruent triangles are congruent.
