Answer:
below.
Step-by-step explanation:
408 = 2*2*2*3*17
1032 = 2*2*2*3*43
So the HCF is 2*2*2*3 = 24
24 = 2/1032 + p/408
24 - 2/1032 = p/408
p = (24 - 2/1032) * 408
p = 9791.21 to nearest hundredth.

Answer:
The correct ordered pair is (7,1)
Step-by-step explanation:
The given system has equations:
We make x the subject in the first equation to get:
Put equation 3 into equation 2 to get:
Expand:
Put y=1 into equation 3 and solve for x.
The correct ordered pair is (7,1)
Answer:
r = -40
Step-by-step explanation:
1. Move constants to the other side of the equation
r = 16/-.04
2. Simplify (by calculator)
You can use a calculator and plug in 16/-.04
r = -40
2. Simplify (by fraction)
You can turn -.4 into a fraction.
-.04 = - 4/10
r = 16/-(4/10)
r = 16*10/-4
r = -40
Answer:
3r + 2b is the simplest form, are you missing anything?
