7 video games were in each case.
Step-by-step explanation:
-So, Ricardo has 2 cases of video games with the same amount of games per case.
-He gives 4 games to his brother and is left off with 10 games.
Add 10+4 to get the total amount of games.
Since there are 2 cases, divide the total amount of games (14) by the total amount of video game cases.
This gets us 7, which is the starting amount of video games in each case.
Lets solve this!
175/16.46= 10.6318347509
so , your answer is 10.6318347509.
Hope this Helps!
We want to solve for a
-a + 7 = 2a - 8
we will add 8 to both sides and simply to
-a + 15 = 2a
We will then add a to both sides and simply to
15 = 3a
We then divide by 3 on both sides to get
a=5
Answer:
B. 2 x 10^2 m^3
Step-by-step explanation:
Given
Volume of submarine when full of water= 7.8 × 10³ m³
Total mass of submarine =8× 10⁶ kg
Density of sea water= 1000 kg/m³
Volume to be occupied by sea water at given mass of submarine=?
Apply; Density=mass/volume ⇒⇒volume=mass/density
where M=mas, V=volume, D=density
Excess volume= 8×10³ - 7.8× 10³ = 2×10² m³
