X=60
That’s the answer
What I did to get it
(3x-60)=120
+60. +60
3x =180
————. = 60
3
X=60
<span>-1 + n=8(n+6)
Use distributive property
-1 + n= 8n + 48
Subtract n from both sides
-1= 7n + 48
Subtract 48 from both sides
-49= 7n
Divide 7 on both sides so that the only thing remaining on the right sides is the varible n.
Final Answer: -7 = n</span>
110 liters. 1000ml = 1 liter. Move the decimal 3 places to the left,so 110,000 ml becomes 110 liters.
<h3><u>Given</u>:-</h3>
Radius(r) of sphere = 3m
<h3><u>To Find</u>:-</h3>
Volume of the sphere.
<h3><u>Formula Used</u>:-</h3>
Volume of sphere = 
<h3><u>Solution</u>:-</h3>
Volume of sphere = (putting the value of r(radius) from the above given and pie(π) = 
)
Therefore, the volume of the sphere , which can be rounded off to it's nearest tenth as

<span>Let each side perpendicular to the river be
"x".
Then the side parallel to the river is "2400-2x".</span>
The function would be:
<span>A(x) = x(2400-2x)
</span>
And it would be: A(x) = 2400x - 2x^2
To solve the equation:
<span>
You have a quadratic with a = -2 and b = 2400
</span>
Maximum Area happens where:
x = -b/2a
= -2400/(2*-2)
<span>= 600 ft. (width)
</span>
To find the length it will be:
<span>= 2400-2x = 2400-2*600 = 1200 (length)</span>
