Answer : b= -1
just move -7 to the right side of the equal sign so you will know what b equals. So now -7 is a postive number ( 7) -8+7 = -1
so B= -1
Answer:
2 animals
Step-by-step explanation:
Number of animals=40
Fraction of fish=3/4
=>number of fish=3/4*40=30
Fraction of cats=1/5
=>number of cats=1/5*40=8
Animals which are not cats or fish are=total number of animals-(number of cats + number of fish)
Animals which are not cats or fish=40-(8+30)
40-38
2 animals
Volume of the cube is given as 512 cm^3
We also know that
Volume of a cube = (side)^3
Then we can use this formula to find the size of each side of the cube very easily.
Let us assume the length of each side = x
Then
x^3 = 512
= 8
So the length of each side of the cube is 8 cm. I hope you have got the answer you were looking for. You can crosscheck the answer by multiplying 8 three times. You will get the result as 512. This is the only method to solve this problem.
