Well this isn't college math lol
You do 19x + 13x + 4x = 26x
180 divided by 26x = x = 6.92307...
plug in x then round to tenth
6.9 x 19 = 131.1 degrees
6.9 x 13 = 89.7 degrees
6.9 x 4 = 27.6 degrees
Answer:
3 1/4
Step-by-step explanation:
3/4 + (1/3 divided by 1/6) - (- 1/2)
first calculate between the brackets.
(1/3) / (1/6)
Division is the inverse of multiplying.
(1/3) * (6/1)
multiply both numerators and multiply both denominators
1*6 / 3*1 = 6/3 = 2
3/4 + (2) - (- 1/2)
make all denominators into 4
3/4 + (8/4) - (- 2/4)
- ( - = plus
3/4 + (8/4) + 2/4
3/4 + 8/4 + 2/4
add all numerators since the denominators are all the same.
( 3 + 8 + 2 ) / 4
13/4
3 1/4
3.25
Answer:
11x-2y
Step-by-step explanation:
Combine like terms so 2x+9x=11x AND -4y+2y=-2y so answer follows as 11x-2y
3x-12 ≥7x+4
Subtract 3x from both sides
-12 ≥4x+4
Subtract 4 from both sides
-16 ≥4x
Divide each side by 4
-4 ≥x
From point 4, you use a closed circle and the arrow is facing towards 0
