X+ 1.5x - 4.5 = 5/2
2.5x - 4.5 = 5/2
2.5x = 5/2 + 4.5
2.5x = 7
x = 7/2.5
X = 2.8
Answer: The first one.
Step-by-step explanation:
Since 1.5 + 2.5 = 4, and the only graph that has an arrow pointing to 4 is the first one, then the first number line is the correct answer.
Hope this helps :)
Density is calculated by mass divided by volume.
This would be 60/24 (60 grams mass divided by 24 cm^3 volume)
60/24 = 2.5
This means the answer is B. 2.5 g/cm^3
The answer is C because when you rotate 90 degrees clockwise (x,y) becomes (y,-x)
