Answer:

x = -3

Step-by-step explanation:

3х - 5 = 10 + 8x

Subtract 3x from each side

3х-3x - 5 = 10 + 8x-3x

-5 = 10+5x

Subtract 10 from each side

-5-10 = 10+5x -10

-15 = 5x

Divide each side by 5

-15/5= 5x/5

-3 =x

Elina [12.6K]

Solution:

The following information about the chain email can be Written as follows:

1 Person Email →→6 Persons (E-mail) →6² Persons  (E-mail)→6³ Persons  (E-mail)+.........few Days

As you can see the number of email sent starting from person 1 to 6 persons to 36 persons to 216 persons, forms a Geometric pattern.

So, Sum of the Series = 1 + 6 + 36 + 216 + 1296 +......+  for n days

        = 1+6^1+6^2+6^3+6^4 +6^5 +6^6+..........+ 6^n

Formula for n terms of a geometric series

\frac{a (r^n-1)}{r-1}

For, Common ratio (r)≥1

Sum of above geometric series up to n terms =\frac{6^n-1}{6-1}=\frac{6^n-1}{5}

I really need help with this​
Marrrta [24]

Answer:

G=21, F=9, M=6, L=7, E=20, D=15, B=10, R=12.5, T=16, N=13.5, W=18, H=36, Z=12

*I=5*

Step-by-step explanation:

I basically just found the scale factor/proportion from two given sides and then used that to find the remaining sides.

*I'm not sure about 'I' since the edge of the paper was cut off so I want sure if it was a 5 or a 15 on the left most problem in the third row. I assumed it was 15. If it's not, just shout it out in the comments and I'll fix it! :)*

You can fill the letters in at the bottom XD

I hope this helped! :D
