Yes they are right you did a great job!
Answer:
breadth = 8, length = 32
Step-by-step explanation:
perimeter = 2 x (length x breadth)
= 2 x ((24 + b) + b))
= 2 x (24 + 2b)
= 48 + 4 b
48 + 4b meters costs rupees 2400
each meter costs rupees 30
so,
30 x (48 + 4b) = 2400
1440 + 120b = 2400
120b = 960
b = 8
the breadth is 8m, the length is 8 + 24 = 32m
Answer:
Do the parentheses first. then the operations. Then solve
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
First thing you gotta do is find the common denominator.
Do this by listing factors of the denominators:
5- 5, 10, 15, 20, 25, 30
6- 6, 12, 18, 24, 30, 36
5 and 6 both have 30 in common so that's the new denominator for all 3 of the terms.
What you do to the bottom you must do to the top.
Since you multiply 5 by 6 to get 30, you must multiply 2 and 4 by 6 as well.
Since you multiply 6 by 5 to get 30, then multiply 5 by 5 as well.
The new equation is:
+
+
=
Now add the numerators together
The solution is
. Now simplify. 61 is prime, so you cannot change the fraction How many times does 30 go into 61? Two times. This gives us 2
