Answer: 66.66% rise
Step-by-step explanation:
350-210=140
140/210 =2/3
66.6% rise
Answer:
It is a 40% increase
So first of all the formula is
New-old/old
Or rate of change/ original
SO th new is 350
THe old is 210
140/350 which is old is 2/5
2/5 is 40 percent
So 40 percent increase
37
if lucy was half lisa's age at 6, that means she was 3. so there's a 3 year difference between the two sisters, so now if Lisa is 40, that makes Lucy 37.
5 is the value of x
x=35
3x+7+68=180
3x+75=180
3x=105
