Answer:
c.
Step-by-step explanation:Because it's c.
So there are 2 numbers
pretend the smaller number is x, so the larger number must be 2x because it's twice as large
so 2x+x equals 54
simplifies to 3x=54
x= 18
the smaller number is 18 and the larger one is 36 (because 36 is 18 x 2)
Answer:
they are both true
Step-by-step explanation:
they are both true because of proportionalities
5/8
5x2=10
8x2=16
therefore 5/8=10/16
the second one is also true because they want you to multiply y by 2
4x2=8
therefore
5/8=5/4x2
