Step-by-step explanation:
Answer:
It will take 5 months and that height will be 20cm.
Step-by-step explanation:
Let the height of the tree be h cm and the number of months be m.
<u>Maple</u><u> </u><u>tree</u>
Initial height= 10cm
Total height= 10cm +2(number of months)
h= 2m +10 -----(1)
<u>Oak</u><u> </u><u>tree</u>
Initial height= 15cm
Total height= 15cm +1(number of months)
h= m +15 -----(2)
When the height of the two trees are the same,
2m +10= m +15
Solve for m:
2m -m= 15 -10
m= 5
Substitute m=5 into either equation 1 or 2 to obtain the height.
When m=5,
h= 5 +15
h= 20
3x+6=3(x+2)
x-2= -(2-x)
15x-10/5= 3x-2
They all had in common a 2
