Answer:
A
Step-by-step explanation:
First, we need to find the unknown angle of the triangle.
40 + 20 = 60
180 - 60 = 120
So the unknown angle is 120.
Then, we can use the law of sines to create a proportion.
sin(120)/8 = sin(40)/a
Then, we can simplify this.
a is about 5.9, or answer choice A.
Answer:
0.025
Explanation:
Divide the percentage by 100 to convert it to decmals.
for example 20%=
20
100
=.2
30%=
30
100
=
.3
2.5%=
2.5
100
=
.025
1.) The error is that she attached the
variable with the flat fee (which is
constant) and put the daily rent as a
constant (which is variable).
The correct equation is:
365+125x=250+175x
2.) N=5
3.) k=-35.
Explanation: Solution:
17k-6=37k+4 . 17k-37k=4+6 .
-27k=10 . k=10\cdot(7-2) . k=-35 .
4.)
.
Your answer is
<span>x>-12
</span>
How?
Subtract 8<span> from both sides
</span><span>x>−4−8
Simplify <span>-4-8 to -12
</span><span><span>x>−12</span><span>

More than 1 hour.
1/4 + 1/2 is the same as 1/4 + 2/4 = 3/4
3/4 + 1/3 is the same as 9/12 + 4/12 = 13/12
13/12 = 1 1/12
