Answer: 3 & 18
Step-by-step explanation:
x+6x = 21
7x=21
x=21/7
x= 3
21-3 = 18
so 3 and 18
V = pi * r^2 *h
where r is the radius and h is the height of the cylinder
V = pi * 7^2 *4
V = pi* 49*4
pi is approximated by 3.14 or 22/7
V = 22/7 * 49 * 4
V = 616 units ^3
Square root of 5 because it gives no real solution.
Step-by-step explanation:
Simplifying
1.5x + -2.5x = 3
Combine like terms: 1.5x + -2.5x = -1x
-1x = 3
Solving
-1x = 3
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '-1'.
x = -3
Simplifying
x = -3
Hey!
Okay, to solve this problem, we'd first have to multiply both sides by two. The reason we do this is to get
on its own.
<em>Original Equation : </em>

<em>New Equation {Changed by Simplification} :</em>
y < -6
<em>So, the equation
< -3 simplified is</em>
y < -6.
Hope this helps!
