((7x+2)/3) -((9x -2)/5) =2

12) ((4n+1)/3)-1(1/2)=((2n+5)/6)

Ex 6d
9) The result of taking 3 from x and multiplying the answer by 4 is the same as taking 3 from five times x.
a.) Express this statement as an algebraic equation
b.) Hence find the value of x
One stick is 9cm longer than another. 2/5 of the longer stick equals to 1/2 of the shorter stick. Find the length of the longer stick

c. side angle side. u shares the same sides

well what did you do it matters what you did : )

step-by-step explanation:

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.

60 for the first and 130 for the second
