james wants to compete in the international speed texting competition next year where

participants compete on text speed and accuracy. james's current text speed is 2

characters per second, james has found that his texting speed increases at a rate of 1/2 a

character per second for each month that he practices.

1. a. what is james's new texting speed if he practices for only 1 month?

b. what is james's new texting speed if he practices for 2 months?

c. what is his new texting speed if he practices for 3 months?

d. write an algebraic equation that gives james's texting speed s for m months of

practice.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
