Answer:
x=54
Step-by-step explanation:
easy
180 is a triangle
so
exterior+interior=180
so 180-123
57
now add all up to 180
180=57+x+69
x=54
You divide 30 miles by 10 to get 3 miles, so you do the same for the bottom.
20 hours divided by 10 = 2 hours.
2 hours is the answer.
W > Y + H/P
W - Y > H/P
P(W - Y) > H
H < P(W - Y)
It’s -37! | this means the opposite of the number ;)
Let x = width
<span>length is 8 cm more than three times it’s width so length = 3x + 8
</span>
Perimeter of a rectangle = 2(L + W)
so
128 = 2(x + 3x + 8) solve for x (width)
128 = 2(4x + 8)
64 = 4x + 8
4x = 56
x = 14
width = 14 cm
length = 3(14) + 8 = 50 cm
Answer:
width = 14 cm
length = 50 cm
