how do you think you can represent the number 2300 as a number times a multiple of 10? How do you think you can represent the number 2300 as a number x 10 to some exponents? How could you describe the relationship between the two representations?

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

i think is g(1)=-1.

hope that i can

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.
