7m+8=71 how do i answer this question it's a two-step equation

m=9

Step-by-step explanation:

It's very simple.

First, you have to subtract 8 to both sides.

7m+8=71

      -8  -8

Then, once you've subtracted, your left with 7m= 63. Now you have to divide to both sides.

7m= 63

  7     7

In conclusion, once you've divided, you are left with your answer.

m=9

2^y = ln 5, or   y(ln 2) = ln 5.   solving for y,   y = (ln 5) / (ln 2).   y=5

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
