Answer:
just find out how much does a quarter and nickel cost then multiply it by the number of coins (nick or quart)
Step-by-step explanation:
Answer:
-2(8)=16
Step-by-step explanation:
-2(8) is equal to -2 times 8/ -2 x 8
So 2 times 8 is 16, but since it's negative 2 it takes the negative sing
4 2/3 * 11 1/4
14/3 * 45/4 = 630/12 = 52 6/12 = 52 1/2
OPTION B IS YOUR ANSWER....
For the exponential expression,
the simplified value is 2.

How to simplify the exponential expression?</h3>
First, we need to remember a rule for exponential expressions, it says that:
![x^{1/n} = \sqrt[n]{x}](https://tex.z-dn.net/?f=x%5E%7B1%2Fn%7D%20%3D%20%5Csqrt%5Bn%5D%7Bx%7D)
Then we can rewrite the given exponential expression as:
![16^{1/4} =\sqrt[4]{16}](https://tex.z-dn.net/?f=16%5E%7B1%2F4%7D%20%3D%5Csqrt%5B4%5D%7B16%7D)
So, we just need to find a number that when multiplied by itself 4 times, is equal to 16.
We know that:
2*2 = 4
Then:
2*2*2*2 = 2⁴ = 4*4 = 16
Then we can conclude that:
![16^{1/4} =\sqrt[4]{16} = 2](https://tex.z-dn.net/?f=16%5E%7B1%2F4%7D%20%3D%5Csqrt%5B4%5D%7B16%7D%20%3D%202)
So the simplified value of the exponential expression is 2.

Answer:
392 minutes
Step-by-step explanation:
She reads 6/7 of a page in 12/5 mins
She will read 1 page in (12/5)* (7/6) mins
She will read 140 pages in (12/5)*(7/6)*140 mins = 392 mins
