Answer:
y=4
Step-by-step explanation:
A) The roof would be horizontal
b) The roof would be vertical
c) The roof rises 5 feet
d) The peak is 15 feet from the front
e) Pitch = slope = rise / run
Pitch = 5/15 = 1/3
<span>4(2x + 3y)
The first step is distribution.
Multiply 4 by every term in the parentheses.
</span><span>
(4*2x) + (4*3y)
8x + 12y
The simplified version of </span>4(2x + 3y) is 8x + 12y.
You can't simplify further because you have two different variables, x and y, which can't be combined.
Answer:
0 y -6 o 1 y -7
Step-by-step explanation:
Answer: The conversion factor between km and m is 1 km = 1000 m, and between hr and seconds, it is 1 hr = 3600 s. Let's first convert 9 km/hr to m/hr.
9 km/hr x (1000 m / 1 km) = 9000 m/hr
Then use the 2nd conversion factor to convert hr to seconds.
9000 m/hr x (1 hr / 3600 s) = 9000 / 3600 m/s = 5/2 m/s
