You can solve a system using substitution, elimination, or graphing method.
If you solve using substitution or elimination, the variable will cancel out on both sides and you will be left with a number equal to a number. If "number = number" is a TRUE statement, then the solution is ALL Real Numbers. <em>If it is a FALSE statement, then you will have NO solutions.</em>
If you solve using the graphing method and the lines are exactly the same, then the solution is Infinite solutions (aka ALL Real Numbers). <em>If the lines are parallel, then you will have NO solution.</em>
Answer:
p = .007
Step-by-step explanation:
prob of blue
1st marble
P = 6/13
2nd marble
P = 5/12
3rd marble
P = 4/11
-----------------------------
all three blue
p = 6/13 * 5/12 * 4/11
p = 0.06993006993
Rounded
p = .007

We know that formular for volume of pyramid=area of base ×height
the area of the base is 1/2×base×height
=1/2×15×14
=105cm²
the given volume is 270cm³
∴height=volume÷base area
=270cm³÷105cm²
=
=
