<em>Answer: There are 5 trumpet players and 15 saxophone player</em>
<em>Step-by-step explanation: Let a be the number of trumpet players
</em>
<em>Let b be the number of saxophone players
</em>
<em>---------------------
</em>
<em>(1) a = b-10
</em>
<em>(2) b =3a
</em>
<em>----------------
</em>
<em>Substitute </em>
<em>(2) into (1)
</em>
<em>(1) a =3a-10
</em>
<em>(1) 2a =10 </em>
<em>
</em>
<em> (1) a = 5and
</em>
<em>(2) b = 3(5)(2) </em>
<em>b = 15

Question:
Escape park owner want 30% of each order to include long boards he wants to know how many long boards to order out of a total of 50 skateboards
Step-by-step explanation:
Let x and y represent the number of long board and the total number of skateboard to order.
Given that 30% of each order to include long boards;
x = 30% of y
x = 0.3y .....1
But, the total number of skateboard is given as 50
y = 50
From equation 1
x = 0.3y = 0.3(50)
x = 15
He should order 15 long boards

How To Find Volume of Pyramid With Slant Height? If 'x' is the base length, 's' is the slant height, and 'h' is the height of a regular pyramid, then they satisfy the equation (the Pythagoras theorem) (x/2)2 + h2 = s2.
If you’re looking for a equation it could be “ 24c + 15 = 687 “
