Sue claims that the solution to the equation 12x-3(5+4x)=7x+20 is x =-5 she shows the steps below to justify her solution
Answer:
Sue is correct and I did the steps below.
Step-by-step explanation:
12x-3(5+4x)=7x+20
12x-15-12x=7x+20
-15=7x+20
-35=7x
-5=7
x = -1+y
2x - y = 0
All of this is one question it’s simultaneous equations. Can someone please help
Answer:
y = 2
Step-by-step explanation:
x= -1+y
2x-y=0
2(-1+y)-y=0
-2+2y-y=0
-2+y=0
-2+2+y=0+2
y=2
hope it's helpful ❤❤❤❤
THANK YOU.

The Teknomite Corporation must appoint a president, chief executive officer (CEO), a chief operating officer (COO). It must also appoint a planning Committee with three different members. There are eight qualified candidates, and officers can also serve on the committee. How many ways can the officers be appointed? How many different ways can the committee be appointed?
Answer:
336 ways ;
56 ways
Step-by-step explanation:
Number of ways to have the officers :
Number of qualified candidates, n = 8
Number of officer positions to be filled = 3
A.)
Using permutation (since the ordering matters):
nPr = n! ÷(n-r)!
8P3 = 8! ÷ (8-3)!
8P3 = 8! ÷ 5!
8P3 = (8*7*6)
8P3 = 336 ways
B.) Different ways of appointing committee: (ordering doesn't count as officers can also be appointed)
Using the combination relation :
nPr = n! ÷(n-r)!r!
8C3 = 8! ÷ (8-3)! 3!
8C3 = 8! ÷ 5!3!
8C3 = (8*7*6) ÷ (3*2*1)
8C3 = 336 / 6
8C3 = 56 ways

What is the volume of a cylinder, in cubic centimeters, with a height of 2 centimeters
and a base diameter of 20 centimeters? Round to the nearest tenths place
Answer:
V ≈ 628.3 cm³Step-by-step explanation:
Volume of cylinder: V = π×r² × h
diameter = 20 cm ⇒ r = 10 cm
h = 2 cm
Volume:
V = π×(10)²×2 = 200π cm³ = 628.318.... cm³ ≈ 628.3 cm³

Step-by-step explanation:
(3.8^3)^4
^ = exponents
[tex](3.8^{3} )^{4}[/tex]
Now lets do the parenthesis first
3.8 * 3.8 * 3.8 = 54.872
[tex](54.872)^{4}[/tex]
54.872 * 54.872 * 54.872 * 54.872 = 9,065,737.908494995
We can round that up to
