The airplane in the scale drawing has a wingspan of a feet and a tailspan of b feet. if the tailspan in the drawing is 2 inches, and ab = 3, what is the actual wingspan of the airplane?

1. are the triangles similar and if so why? what is the value of x? show your work.

Sh what is the value of x? ox= 2.25 x = 11.25 ox= x = 22 1 (2x + 10) seo - (6x + 1) -- nie

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
