Answer:
<h3>Mathematical model =
</h3><h3>k = 0.09422</h3>
Step-by-step explanation:
If v varies jointly as p and q, this means that v varies directly as the product of p and q as shown;
... 1
k = constant of proportionality
Also v varies inversely as the square of s; mathematically,
Equating 1 and 2, we have;
Given v = 1.6, when p=4.1, q=7 and s=1.3
The constant of proportionality is 0.09422
The expression therefore becomes
20+5=25 then 25-4.67=20.33 so then you do 20.33/4.5=4.5 so the cost for one pound of fruit is $4.57. Hope this helps :)
C.) 2 is the right answer
Step-by-step explanation:
Given
-15(x-__)=25
We can see in the next step
We can check by substituting each option one by one
So,
A.) -30
We can see that by putting -30 we don't get the expression given in the picture so it is not the right answer.
B.) -2
We can see that by putting -2 we don't get the expression given in the picture so it is not the right answer.
C.) 2
We get the same expression by putting 2 in the blank so it is the right answer.
Hence,
C.) 2 is the right answer

Answer:
x ≥ 8
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define inequality</u>
-36x - 24 ≤ -6(5x + 12)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -6: -36x - 24 ≤ -30x - 72
- Add 36 on both sides: -24 ≤ 6x - 72
- Add 72 on both sides: 48 ≤ 6x
- Divide both sides by 6: 8 ≤ x
- Rewrite: x ≥ 8
Here we see that any number <em>x</em> greater than or equal to 8 would work as a solution.
