Answer:In 8 years the tree will have the same height.
Step-by-step explanation:
Step 1:
Let x = the number of years when the two trees will be the same height.
For the 2ft tree, you can express its height in x years as:
2+1(x)
And for the 6ft. tree...
6+0.5(x)
Step 2:
2+x = 6+0.5x Subtract 0.5x from both sides.
2+0.5x = 6 Now subtract 2 from both sides.
0.5x = 4 Finally, divide both sides by 0.5
x = 8
Answer:
80
Step-by-step explanation:
If we consider 10s as a block, we would be asking how many blocks (of 10) does 800 have?
We can figure it out by dividing 800 by 10. That is the NUMBER OF TENS 800 will have. So,
800/10=80
Hence, there are 80 tens in 800.
