If you would like to simplify <span>a - {4b - [a - (5b - c) + 3c - (a - b - 9c)]}, you can do this using the following steps:

</span>a - {4b - [a - (5b - c) + 3c - (a - b - 9c)]} = a - {4b - [a - 5b + c + 3c - a + b + 9c]} = a - {4b - [- 4b + 13c]} = a - {4b + 4b - 13c} = <span>a - {8b - 13c} = a - 8b + 13c
</span>
The correct result would be b) <span>a - 8b + 13c.</span>

3. Six less than twice a number is 17. Which equation could be used to determine the

Usimov [2.4K]

Answer & Step-by-step explanation:

n represents our number. So, twice a number would be 2n because twice means multiply by two.

When the problem says 6 less, then it means 6 less than 2n. So, it would look like 2n-6.

FInally, the problem says that all of this equals 17 so 17 would be the result.

So, you answer is 2n-6 = 17. This is answer choice B.

Suppose that you have an enormous grapefruit that is 92% water (by weight). The grapefruit weights 100 pounds. If the water cont

yuradex [85]

Answer:

The weight of grapefruit is now 80 pound.

Step-by-step explanation:

Consider the provided information.

Let the x is the weight loss. The weight of grapefruit is 100 pounds and water is 92%. After evaporation water is 90%.

Thus the weight loss is:

$0.92\times100-0.90(100 - x) = x$

$92-90+0.90x=x$

$2=x-0.90x$

$2=0.1x$

$x=20$

Hence, the weight loss is 80 pounds.

Therefore, New weight is 100 - 20 = 80 pounds

The weight of grapefruit is now 80 pound.
