Answer:
w = 4
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
13w + 18w + 56 = 180
31w + 56 = 180 ( subtract 56 from both sides )
31w = 124 ( divide both sides by 31 )
w = 4
Answer:
I believe its B, But I am unsure since I haven't done geometry in a couple years.
Answer:
c = 20
Step-by-step explanation:
lets express the word sentence as mathematical equations:
"1/4 of a number c" can be written---> (1/4) x c = c/4
"5 is 1/4 of a number c" can be written ---> 5 = c/4
solving the equation for c
5 = c/4 (multiply both sides by 4 and rearranging)
c = 5 x 4
c = 20
If you expand -9(-2x-3) you get 18x+27 (a minus times a minus is a positive) so the answer is A.
