Answer:
79
Step-by-step explanation:
if you take a look at the problem it looks like it has an even with, so you subtract 152 by 73 to get 79.
3x+8.5 =2.5x + 14.5
subtract 2.5x from each side
.5x + 8.5 = 14.5
subtract 8.5 from each side
.5x =6
multiply by 2
x =12
at 12 weeks they will be the same height
Choice B
Step-by-step explanation:
You can first multiply the width by two. Then you subtract that from you perimeter to figure out your length. Whatever number you get divide it by two and there's your length.
Example:
Perimeter =30 Width=5
5 times 2= 10
30-10=20
20/2=10
So your length equals 10.
I hope this helps!
700/200=7/2 because devide by 100 and then=3 1/2 and half is .5 so=
3.5
Answer:
As the ice cubes get heated, the particles of the ice also start to heat up. This way, through conduction and radiation, the particles start bouncing on one another and the heat transfers. this way, they particles begin to make way for the other, resulting in the solid changing to liquid, because the particles are now farther apart.
Hope this helps
