Answer:
22
Step-by-step explanation:
The answer is 22. You solve the equation 3x+10=7x-6 like so
3x+10=7x-6
-3 = -3
10= 4x-6
+6 +6
16=4x
x=4
You then plug in the value of x to the equation for LM.
7x-6 becomes 7*4-6 which is 22.
Answer: the number of boats that are in the marina is 105.
Step-by-step explanation:
Let x represent the number of boats that are in the marina.
Two-thirds of the boats in the marina are white. It means that the number of white boats in the marina is
2/3 × x = 2x/3
The remaining number of boats will be
x - 2x/3 = x/3
4/7 of the remaining boats are blue. It means that the number of boats that are blue is
4/7 × x/3 = 4x/21
The number of boats left would be
x/3 - 4x/21 = 3x/21
If there are 15 red boats, it means that
3x/21 = 15
3x = 21 × 15 = 315
x = 315/3
x = 105
