Answer:
55 miles per hour
Step-by-step explanation:
given the originally traveled 40 miles in one hour gives us 40 mph, 180 miles in the last 3 hours gives us an average of 60 mph for the second part, 40+60+60+60 (for the 3 hours going that fast) is equal to 220, divide that by 4 to give us our average of 55 mph
3x=x+40(vertically opposite angle)
thus ,
X= 20
Given data:
The given distance is d=26 km.
We know 1 kilometer is equal to approx 0.621 miles.
1km= 0.621 miles
Multiply the above expression with 26 on both sides.
26(1 km)= 26(0.621 miles)
26 km= 16.146 miles.
Thus, 26 kilometer is equal to 16.146 miles
Answer:
Negative 4
-4
Step-by-step explanation:
x+5= -23
-x+y= -1
6y= -24
-24÷6= -4
<span>Supplementary angles are two angles that add to 180 degrees.
The equation is </span><span>4x + 5x = 180.
(combine like terms and simplify) 9x=180
180/9=20
so x = 20
So that would mean 4x= 80.
The smaller angle is equal to 80. Since supplementary angles add up to 180, you have a clue as to what the larger angle measures to.
