Answer:
The number of pounds of almonds the customer purchased
Step-by-step explanation:
The system of equations can be used to represent this situation is as follows:
x + y = 3
8x + 14y = 31.50
The variable x represents the amount in pound of peanuts.
The almond cost $8 per pound and peanuts cost $14 per pound.
Therefore,
let
x = amount in pounds of almond
y = amount in pounds of peanuts
The customer bought a total of 3 pound. Therefore,
Total weight in pounds:x + y = 3The customer paid a total of $31.50 for the 3 pounds mixture. Therefore,
Total cost :8x + 14y = 31.50Therefore, the variable x represents the amount in pound of peanuts.

A ship must have 1 lifeboat for every 12 passengers, plus one lifeboat for
the crew and one backup lifeboat. Which equation shows the
relationship between the number of passengers, p, and the number of
lifeboats needed, I?
Select one
1) I= 2 + 1/2
2) I= 2p + 10
3) I= 12p
4)I=2+ p/12
===========================================
Explanation:
p = number of passengers
L = number of lifeboats
Since we're grouping the passengers in groups of 12, this strongly implies we'll be dividing two values. Specifically we have p divided by 12 to represent the number of boats we will need just for the passengers.
For example, let's say p = 36. This means we have 36 passengers. That would mean we need p/12 = 36/12 = 3 boats for those 36 passengers. This excludes the crew and backup boat. Adding those two extra boats leads to the expression 2 + p/12 which is the total number of lifeboats needed.
In the event that p is not a multiple of 12, this leads to p/12 not being a whole number. We could have say p = 50 passengers which means p/12 = 50/12 = 4.167 approximately. We will not round this to 4 because then we'll have passengers without a lifeboat.
We must round 4.167 up to the nearest whole number to get 5. The first four boats take care of 4*12 = 48 passengers, while that 5th boat handles the remaining 50-48 = 2 people. Since 2 people in a boat seems like a really low count, the crew could likely spread the people out such that say 10 people would be in each boat (since 50/10 = 5).
So in short, the result of p/12 is rounded up to the nearest whole number.

Answer:
x = 12
Step-by-step explanation:
18:24 (comparing the same sides for the similar shapes; 18 and 24) when simplified down is equal to 3:4.
Using this 3:4 scale factor we can find the missing side x.
Solving for x :
[tex]\frac{3}{4}[/tex] × 16 = 12
x = 12
OR: Set up a proportion:
[tex]\frac{24}{16}[/tex] × [tex]\frac{18}{x}[/tex]
cross-multiply
16 × 18 = 288
24 × x = 24x
288 = 24x
x = 12
Twenty people attended a going away party for Zach.The guest left in groups of 2.By 9:00,x groups had left.Rewrite the number of guests remaining at 9:00 as a sum.
Answer:
The number of guests remaining at 9:00 is;
(20-2x)
Step-by-step explanation:
From the question, we are told that x groups have left
Since they are leaving in groups of 2, x groups means a total of x * 2 = 2x
So we have 2x left out of a total 20; the people remaining at the party will be;
20-2x
