Membership in the Volunteers Club increased by 15% from last year. If the number of members last year was m, complete a simplified expression to represent the number of members this year.

a simplified expression to represent the number of members this year is: x = 1.15 * (m)

Step-by-step explanation:

For this case what you can do is the following rule of three:

m ---> 100%

x > 115%

Clearing the value of x we have:

x = (115/100) * (m)

x = 1.15 * (m)

if you need , reply with more info. u.

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
