Answer:
2.25
Step-by-step explanation:
6 · 3/8 = 18/8 = 2.25
N=8 is the correct answer
Answer:
Step-by-step explanation:
A line perpendicular to the y-axis, which is vertical, is a line that is horizontal. Perfectly horizontal lines always have a slope of 0. Thus, the equation of the line perpendicular to the one given and passing through the given point (5, 1) is
y - 1 = 0(x - 5) and
y - 1 = 0x - 0 and
y - 1 = 0 so
y = 1 is the equation you're looking for.
Answer:
x = 5
Step-by-step explanation:
11. <C=46 degrees
<D = - 1+8x
<B = 180 - (18x+5)
<C + <D + <B = 180 degrees
46 - 1 + 8x + 180 - 18x - 5 = 180
-8x = 180 - 180 -46 +1 +5
-8x = -40
x = -49/-8
x = 5
When you add any fractions, you need to find a common denominator. In this case they have no common factors so you just multiply them together. First multiply the first fraction by
which gets you
. Then multiply the second fraction by
to get
. Now you can add them together to get
.
(b)
now you can pull out root 2 and get
which equals
