Help PLS Which value of n makes the equation (4n - 10) + 4 = (6n - 9) true?

n= 3/2

yes!

Step-by-step explanation:

calculate the sum 4n-6=6n-9

move the varaible to the left hand side and change its sign

4n-6n-6=-9

collect terms -2n=-9+6

dive both sides of the equation by -2

ANSWER  n=3/2        

3 is ontop and 2 is on the bottom

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.

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
