I don’t really know? What grade is this?
If AB = CD, then AB/n = CD/n. with mÐa in any expression. If AB = CD, then you may replace CD with AB in any expression. Transitive Property of Equality If mÐa = mÐb and mÐb = mÐc, then mÐa = mÐc. (Brainliest Answer Will be appreciated:D)
Answer:
x=8
y=16
Step-by-step explanation:
2x+2y=48
3x+y=40
Ther is many ways to solve this, one of them is clearance:
WE CLEAR AN UNLOCKED (X) AND REPLACE IT IN THE OTHER
x= (40-y)/3
2[(40-y)/3] +2y=48
(80-2y)/3 +2y=48
(80-2y+6y)/3=48
80+4y=48(3)
4y=144
y= 144/4
y=16
x=(40-y)/3
x=(40-16)/3
x=24/3
x=8
Answer:
B
Step-by-step explanation:
I think it is B because 6 times 5 = 30. So 30 times 1/2 = 60 hope this is correct and it helped and if it is not correct try C and can i get a brainliest
C.) Are the same length
<u>How you know-</u>
No matter how long the rectangle is the diagonals always will measure the same length. Think about two sides of a square, they have to equal the same length because if they were not the same then the shape wouldn't be a square.
