8 0

Answer:

x=8

Step-by-step explanation:

Make all the denominators the same

3(x-4/10)=6(3/5)-2(x-5/15)

(3x-12)/30=18/30-(2x-10)/30

Cancel out all the denominators because they're the same

3x-12=18-2x+10

3x-12=28-2x

Add 12 to both sides

3x=40-2x

Add 2x to both sides

5x=40

Divide both sides by 5

x=8

Element X decays radioactively with a half life of 6 minutes. If there are 790 grams of Element X, how long, to the nearest tent

frosja888 [35]

Answer:

It takes 27 minutes for the element to decay to 35 grams

Step-by-step explanation:

Given:

Initial amount = 790 grams

Final amount = 35 grams

Half life = 6 minutes

To find:

Time taken for the element to reduce into 35 grams = ?

Solutions

Time taken = $half life \times \frac{ log(\frac{ initial amount}{final amount})}{log(2)}$

On substituting the values given, Time taken

= $6 \times \frac{log(\frac{790}{35})}{log(2)}$

= $6 \times \frac{log(22.57)}{log(2)}$

= $6 \times 4.496$

= 26.97

= 27 minutes
