Answer:
X=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
120(2x−2)=240
(120)(2x)+(120)(−2)=240(Distribute)
240x+−240=240
240x−240=240
Step 2: Add 240 to both sides.
240x−240+240=240+240
240x=480
Step 3: Divide both sides by 240.
240x
/240
=
480
/240
x=2
Answer:
a) 8²
b) 2⁴ and 5⁴
Step-by-step explanation:
The power of a number is the base together with the exponent of the number.
The given expresion is
![( {8}^{2} )^{3}](https://tex.z-dn.net/?f=%28%20%7B8%7D%5E%7B2%7D%20%29%5E%7B3%7D%20)
We can rewrite this as:
![{8}^{2} \times {8}^{2} \times {8}^{2}](https://tex.z-dn.net/?f=%20%7B8%7D%5E%7B2%7D%20%20%5Ctimes%20%20%7B8%7D%5E%7B2%7D%20%20%5Ctimes%20%20%7B8%7D%5E%7B2%7D%20)
Over here the power being multiplied is
![{8}^{2}](https://tex.z-dn.net/?f=%20%7B8%7D%5E%7B2%7D%20)
Also, the powers being multiplied in
![( {2}^{4} )( {5}^{4} )](https://tex.z-dn.net/?f=%28%20%7B2%7D%5E%7B4%7D%20%29%28%20%7B5%7D%5E%7B4%7D%20%29)
are 2⁴ and 5⁴
Answer:
3/14
Step-by-step explanation:
There are 14 marbles, 5 are yellow, 6 are blue, and 3 are pink. You have a 5/14 chance to get a yellow marble, a 6/14 chance to get a blue marble, and a 3/14 chance to get a pink marble.
I hope that this helps :)
