ab-c=x
x=ab-c
Answer:

Step-by-step explanation:
The composite solid consists of a cylinder and a cone. Therefore, its total volume will be the sum of the volumes of the cylinder and cone:
Volume of the cone: 
Volume of the cylinder: 
Thus, the total volume of the solid is:

Answer:
(Y × 10) + X = 30
hope it helps
Step-by-step explanation:
Y = Cost of each ticket
X = cost of entry fee
so he bought 10 tickets
so you multiply cost of each ticket ( y ) by 10
then you add the entry fee ( x ) to find the total cost ( $30 )
Answer:
1'/4
Step-by-step explanation:
perimeter of a triangle is a + b + c
15 = 5n+n+2n-6+1
15 = 8n - 5
15 - 5 = 8n
10 = 8n
n = 10/8
n = 1'/4
Subtract 100 from both sides
50x = 150 + 30x - 100
Simplify 150 + 30x - 100 to 30x + 50
Subtract 30x from both sides
50x - 30x = 50
Simplify 50x - 30x to 20x
20x = 50
Divide both sides by 20
x = 50/20
Simplify 50/20 to 5/2
<u>x = 5/2</u>
<em>In decimal: 2.5</em>
