Answer:
-9
Step-by-step explanation:
2(n+6) -15 = 5n+18
2n + 12 - 15 = 5n + 18
2n - 3 = 5n + 18
2n = 5n + 21
-3n = 21
n = -9
Answer:
n = -20
Step-by-step explanation:
Subtract 34 on both sides of the equation:
n = 14 - 34
n = -20
Hope this helps!
Answer: x = 70, y = 110, z = 85
Step-by-step explanation:
If BE = CD, then using corresponding angles (are equal), x = 70
If x = 70, then 70+y = 180 (angles on a straight line)
y = 110
And z = 85 (corresponding angles again): angle ABE = angle ACD
Answer:
6 hours. ( I DID IT USING PROPORTIONS!)
Step-by-step explanation:
houses/hours
130/2.5= 312/x
(cross multiply)
130x = 780
130x/130 = 780/ 130 (divide each by 130)
6 = h
