Answer:
10 books approx
Step-by-step explanation:
Step one:
Given data
Hight of cupboard= 1.21m
Thickness of book= 12.5cm
thickness in meters= 12.5/100= 0.125m
Required
The number of books need to fill the Cupboard
Step two:
the number of books can be computed as
= 1.21/0.125
=9.68 book
=10 books approx
Answer:
See below
Step-by-step explanation:
If an expression is not dependent on x, it simplified form must not contain x. To show that this is the case for (a) and (b) we need to simplify them and assess:
(a)
Indeed, does not depend on x!
And (b)
Again, does not depend on x.
Answer:
x = 5
y = 5
Step-by-step explanation:
In this question you need to solve one equation in order to plug the value into the second one and solve it as well. Lets start with the top one...
2x - x = 5
1x = 5
x = 5
Now we plug that value of x into the second equation
4x - 2y = 10
4(5) - 2y = 10
20 - 2y = 10
-2y = -10
y = 5
Finally, we can see that both x and y have a value of 5.
