Answer:
the answer is 40 boys
Step-by-step explanation:
Let's say there are x boys who play both cards and carrom.
We setup up an equation that involved all information given and x.
Boys who only play cards = 45-x
Boys who only play carrom = 20-x
Boys who play both = x
Add there together and you should get 60, which is the total number of students in the class.
(45-x)+(20-x)+x=60
65-x=60
x=5
Boys who only play cards=45-x=45–5=40
hope it helps you

Answer:
Re-wright the problem as y=4x
Step-by-step explanation:
The number 1934 can be written as:
1,000 + 900 +30 +4
so the value of the 3 is 30, of the 9 is 900 and of the 1 is 1000.
900 is indeed 10 times 30, so
"<span>the value of the 9 in the hundreds place ten times the value of the 3 in the tens place</span>"
