Answer:
A,D,E
Step-by-step explanation:
scaled copy means the ratio of the two lengths would be same proportional constant.
The proportionality constant for Rectangle A is:
12/3 = 4
So any scaled version will have this proportionality constant same (4).
let's check:
A) 6/1.5 = 4 (OK)
B) 10/2 = 5 (NOT OK)
C) 13/4 = 3.25 (NOT OK)
D) 18/4.5 = 4 (OK)
E) 80/20 = 4 (OK)
So, correct options are A, D, and E
What is the LCM of 8, 15, and 24? 120
That means, it would be 120 minutes before they are together again.
120 minutes after 3 pm is 5:00 pm
To solve for x, you first add 5 to both sides so it remains equal.
3 + x = 2
Then you simply subtract 3 on both sides.
x = -1
Substitute your solution into the equation and see it is true.
|3+(-1)) - 5 = -3
The equation is true, therefore your answer is: x = -1
