Answer:
Angle1:12
Angle2:168
Step-by-step explanation:
Angle 1+angle 2=180
X-9+8x=180
9x=189
x=21
angle1=21-9=12
Angle2=180-12=168
Exact form = 23/2
Decimal= 11.5
Mixed number= 11 1/2

A(a+5)+a(3-4) all divided by a(a+5)= a^2+5a+3a-4a all divided by a^2+5a= a^2+4a/a^2+5a
Answer:
The answer is B)
Step-by-step explanation:
First, we look at what we know. There are two points on the graph that we know, (0, 0) and (15, 5). This can give us the slope of the line.
y2 - y1 / x2 - x1 | Plug in our coordinates
5 - 0 / 15 - 0 | 5 / 15 | 1/3. Our slope is 1/3. This means that for each inch of length, the ramp rises .33 inches.
