Answer:
x = 7
and it means that 7 games were rented that month
Step-by-step explanation:
Here, we are to solve for x from the given equation
we have this as:
2.5x + 9 = 26.5
2.5x = 26.5-9
2.5x = 17.5
x = 17.5/2.5
x = 7
What x means in this case is that the number of games rented in the month is 7
Answer:
its already rounded to the nearest hundredth
Step-by-step explanation:
To solve both of these expressions, we want to add or subtract from left to right.
For the first one, we can rewrite it as:
8-6-9
=2-9
=-7
The second one we can rewrite as:
5-7+9+8-4
=-2+9+8-4
=7+8-4
=15-4
=11
The formula for the volume of a pyramid is,
V=1/3Bh
Since the base of the pyramid is a square, the base area is 11^2
which equals 121 sq. units
So, substitute 121
for B
and 6 for h, in the formula.
V=1/3(121)(6) = 242 cu. units
Or alternatively 1/3(11^2)(6) = 242 cu. units
