Answer:
(a)
(b)
(c) Jim initially had 48; Kirk initially had 12
Step-by-step explanation:
Given
Solving (a): An equation for the amount they originally had.
From the question, we understand that j is 4 times as many as k.
Mathematically, this is:
Solving (b): Equation after Kirk wins
Initially Kirk had k.
To get the new expression, we add 18 to k.
This gives: 18 + k
In the same vein, Jim's number of chirps will reduce by 18.
Initially, Jim had j chirps (or 4k chirps)
To get the new expression, we subtract 18 from j.
This gives: j - 18
So, the equation is:
Solving (c): Number of chirps they started with.
In (b), we have:
Substitute 4k for j

Divide both sides by 3
Substitute 12 for k in
F(x) = x^2 + 24x + 138
f(x) = x^2 + 24x + (24/2)^2 + 138 - (24/2)^2
f(x) = (x+12)^2 - 6
Student 3 is correct. This is because you can distribute 3. You would do 3x6m, or 18m, and you can do 3x3, or 9. This means that Student 3 is correct. Since m is not defined as an integer, it can’t be any of the other choices.
Answer:
(3^3*5^3)-2
(27*125)-2
3375-2=3373
Step-by-step explanation:
(3^3*5^3)-2
(27*125)-2
3375-2=3373
Rounding to cents means rounding to hundredths. Since the place to the right of the hundredths place is a 5, we round up, for a result of $4,822.78.
