Solve. 8 – 3x – x = 12 x =?

1 answer:

3 0

You have to isolate x. First you start off by adding the like terms which is -3x and -x. By adding them you get -4x.

8 - 4x = 12

Then you subtract 8 on both sides since it is positive to isolate x.
-4x = 4

Then you divide -4 by both sides and get x=4/-4

4/-4 is simplified to -1 so the answer is x= -1

Find the volume of each figure. Round your answer to the nearest hundredth, if necessary.<br><br>

bija089 [108]

Formula for volume of cone:

V = $\pi r^{2} \frac{h}{3}$

r = 6 km

h = 12 km

V = $\pi 6^{2} \frac{12}{3}$

V = $\pi 36*4$

V = $\pi 144$

V = 452.389 km^3 <----------------------Using the calculators pi button

V = 452.16 km^3 <-------------------------Using 3.14 for pi

Someone please help me <br> The top number is 18

kotegsom [21]

Answer:

x = 24

Step-by-step explanation:

Since this is a right angle, we can use the Pythagorean Theorem to find x. In the formula, a^2 + b^2 = c^2, variables a and b represent the lengths of the legs, and variable c represents the length of the hypotenuse.

a^2 + b^2 = c^2

18^2 + x^2 = 30^2

324 + x^2 = 900

x^2 = 576

x = 24
