Answer:
Option c) y= is correct
The value of y is 3
Step-by-step explanation:
Given equation is
To solve the given equation for y
(converting mixed fraction to normal fraction )
(taking LCM 25 )
(adding the terms )
(now convert fraction into mixed fraction )
Therefore y=
Option c) y= is correct
The value of y is 3
Answer:
2 cm
Step-by-step explanation:
Given that
The length is 13 cm longer than its width
And, the volume of the box is 60cm^3
We need to find out the dimension of the box
Since the box has square ends
So,
the height is equivalent to the width
Let us assume the width be W so the height also be W
Now the length is W + 13
The volume is
W × W × (W + 13) = 60
After solving this W is 2 cm
Answer:
2
Step-by-step explanation:
In general, .
So we have here that:
We went by itself first.
Subtract 441 on both sides:
Multiply both sides by -1:
Take the square root of boht sides:
So both 2 and -2 would satisfy the equation.
Only one of these is a whole number.
The whole numbers consist of the elements that you can count with and 0.
The whole number set is {0,1,2,3,4,5,6,7,...}
So 2 is the answer.
Check:
Replace x with 2:
437=(21+2)(21-2)
437=(23)(19)
437=437 is a true equation so 2 is definitely a solution.
