3.5 is rounded to the nearest tenth.
Answer:
w=57
Step-by-step explanation:
The angles are supplementary because they are adjacent to one another and lies on a straight line
w-8+2w-1=180
Combine like terms
3w-9=180
Subtract 9 on both sides
3w=171
Divide 3 on both sides
w=57
Expression I: 3n + 7 + n + 4n

Step-by-step explanation:
Answer:
x = 4
y = 2
Step-by-step explanation:
by using substitution method ;
now, in second equation ;
- 2x + 3y = 14
- 2 (8 - 2y) + 3y = 14
( since x = 8-2y, from equation 1 )
- 16 - 4y + 3y = 14
- 16 - y = 14
- -y = 14 - 16
- -y = -2
- y = 2
<em>i</em><em> </em><em>hope</em><em> </em><em>it</em><em> </em><em>helped</em><em>.</em><em>.</em><em>.</em>
putting value of y in equation 1, we get :
- x + 2y = 8
- x + (2 × 2) = 8
- x + 4 = 8
- x = 8 - 4
- x = 4
