687.58 is the answer.
Use the formula V= pi(r^2) h/3
Answer:
18
Step-by-step explanation:
Let the number be 'x'
Sum of 'x' and 12 = x +12
The product of 8 and the sum of a number and 12 = 8* (x +12)
= 8*x + 8*12
= 8x + 96
8x + 96 = 240
Subtract 96 from both sides
8x + 9 6 - 96 = 240 - 96
8x = 144
Divide both sides by 8
x = 144/8
x = 18
Answer:
1.11x +3
Explanation:
Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler (usually shorter), for example. Simplification of a fraction to an irreducible fraction. Simplification of expressions, in computer algebra.
Answer:
x = 21
Step-by-step explanation:
Diagonal angles are equal to eachother, so 143 = 6x +17
143 = 6x + 17
Subtract 17 from both sides
126 = 6x
Divide by 6
21 = x
To check put x as 21
143 = 6(21) + 17
Mutiply 6 by 21
143 = 126 + 17
add 17
143 = 143
