Answer:

x=4

Step-by-step explanation:

To remove the radical on the left side of the equation, square both sides of the equation.

√x+4−72=12x+4-72=12

Simplify each side of the equation.

x−3=1x-3=1

Move all terms not containing xx to the right side of the equation.

x=4

8 t-shirts and 5 pairs of pants cost $220 how much does each t-shirt and pair of pants cost
Yakvenalex [24]
Hey, It looks like you're in Algebra and I'm here to give the best solution I can!

To write the equation, you are going to use the Standard Form. Standard Form is one way of solving this problem, and it is used to find the x,and y-intercepts of a problem.
Standard Form can be written using the equation <span>ax+by=c

</span>In your problem, you will write the equation like so, with 'x' representing T-Shirts, and 'y' representing pants:
<span>
8x+5y=220</span>
Now, in order to find the x-intercept you need to substitute a 0 for the 'y' variable and solve the new equation, 8x=220.
I'm sure you know you need to divide both sides by 8 which will give you the answer x=27.5.

Now, in order to find 'y' you would substitute a 0 for the 'x' variable which will give you an equation that should look like 5y=220.
Then, divided both sides by 5 to get your y-intercept.
y=44

Finally,you know that each T-Shirt (x) is $27.50, and each pair of pants(y)costs $44

-I hope this helped you, Sincerely, Auhrevo!

Answer:

4.8

Step-by-step explanation:

V_{sphere} = \frac{4}{3} \pi r^3

144\pi= \frac{4}{3} \pi r^3

r^3 = \frac {3 \times 144\pi}{4\pi}

r^3 = 3 \times 36

r^3 = 108

r =  \sqrt[3]{108}  \\  \\ r = 4.7622031559 \\  \\ r \approx \: 4.8 \:
