Find the value of x​

Mathematics
2 answers:
damaskus [11]3 years ago
4 0

Answer:

x=12

Step-by-step explanation:

First, note that the angles shown are vertical angles. In other words, the two equations are equivalent to each other.

Therefore, set the equations equal to each other and solve for x;

6x+7=8x-17

Add 17 to both sides:

6x+24=8x

Subtract 6x from both sides:

24=2x

Divide both sides by 2:

x=12

Therefore, the value of x is 12.

And we're done!

The sample loses 1/3of it’s mass every ___ days
eimsori [14]

Answer:

The sample loses \frac{1}{3} of its mass every \frac{1}{3} days.

Step-by-step explanation:

Expression that shows the relation between final mass of the element after 't' days is,

M(t) = 900(\frac{8}{27})^t

If M(t) = two third of the initial mass [After the loss of one third of the initial mass remaining mass of the element = 1 - \frac{1}{3} = \frac{2}{3}rd of the initial mass]

900\times \frac{2}{3}=900(\frac{8}{27})^t

\frac{2}{3}=(\frac{8}{27})^t

\frac{2}{3}=[(\frac{2}{3})^3]^t

(\frac{2}{3})^1=(\frac{2}{3})^{3t}

By comparing powers on both the sides

3t = 1

t = \frac{1}{3} day

Therefore, The sample loses \frac{1}{3} of its mass every \frac{1}{3} days.
