Answer:
Hello my friend, I hope this helps you!
Step-by-step explanation:
Yes, they both are 2/7
Proof: Left-hand side
Simplify the following:
12/42
The gcd of 12 and 42 is 6, so 12/42 = (6×2)/(6×7) = 6/6×2/7 = 2/7:
Answer: 2/7
Right-hand side:
Simplify the following:
10/35
The gcd of 10 and 35 is 5, so 10/35 = (5×2)/(5×7) = 5/5×2/7 = 2/7:
Answer: 2/7
Answer:
![The\ weight\ of\ the\ 50\ erasers\ be\ \frac{4000}{n}\ grams.](https://tex.z-dn.net/?f=The%5C%20weight%5C%20of%5C%20the%5C%2050%5C%20erasers%5C%20be%5C%20%5Cfrac%7B4000%7D%7Bn%7D%5C%20grams.)
Step-by-step explanation:
As given
if n erasers have a weight of 80 grams .
I.e
n erasera = 80 grams.
1 erasers weight .
![1\ erasers\ weight = \frac{80}{n}](https://tex.z-dn.net/?f=1%5C%20erasers%5C%20weight%20%3D%20%5Cfrac%7B80%7D%7Bn%7D)
Now find out the weight of the 50 erasers.
![Weight\ of\ 50\ erasers = \frac{50\times 80}{n}\ grams](https://tex.z-dn.net/?f=Weight%5C%20of%5C%2050%5C%20erasers%20%3D%20%5Cfrac%7B50%5Ctimes%2080%7D%7Bn%7D%5C%20grams)
Simplify the above
![Weight\ of\ 50\ erasers = \frac{4000}{n}\ grams](https://tex.z-dn.net/?f=Weight%5C%20of%5C%2050%5C%20erasers%20%3D%20%5Cfrac%7B4000%7D%7Bn%7D%5C%20grams)
![Therefore\ the\ weight\ of\ the\ 50\ erasers\ be\ \frac{4000}{n}\ grams.](https://tex.z-dn.net/?f=Therefore%5C%20the%5C%20weight%5C%20of%5C%20the%5C%2050%5C%20erasers%5C%20be%5C%20%5Cfrac%7B4000%7D%7Bn%7D%5C%20grams.)
the answer is c 3/2 x - 3 = y. :)
Answer:
He should have to spell at least 36 of these words correctly.
Step-by-step explanation:
40 words.
He must spell at least 90% of those words correctly.
At least how many words should he have to spell correctly to get the prize?
90% of 40. So
0.9*40 = 4*9 = 36
He should have to spell at least 36 of these words correctly.
