1 answer:
Consequently, the equation determining the remaining number of rooms Martin has to clean after hours can be represented as:
, in which indicates the overall number of rooms. Step-by-step explanation: It is given that Martin has 4 rooms left to clean and takes 7 hours for the task. The equation in standard form for the number of rooms remaining after x hours, y, is set up as follows: The remaining rooms
, indicates the quantity after
hours. The cleaning rate is established as follows: Considering Martin cleans 4 rooms in 7 hours, the rate at which he cleans is given by: Hence, the equation can be expressed as

Answer:
Option 2 50 ≤ s ≤ 100
Option 5 She can make a deposit of $50
Option 6 She can make a deposit of $75
Detailed explanation:
Let
s represent the amount of money Layla puts into her savings account.
We know that
25% = 25/100 = 0.25
50% = 50/100 = 0.50
Thus
----->

The compound inequality is
Check each case
case 1) 25 ≤ s ≤ 50
This statement is falseRefer to the procedurecase 2) 50 ≤ s ≤ 100
This statement is true
Refer to the procedure
case 3) s ≤ 25 or s ≥ 50
This statement is false
Because s ≤ 100 and s ≥ 50
case 4) s ≤ 50 or s ≥ 100
This statement is false
Because s ≤ 100 and s ≥ 50
case 5) She can make a deposit of $50
This statement is true
As the value of s meets the compound inequality
case 6) She can make a deposit of $75
This statement is true
As the value of s meets the compound inequality
Response:
The correct choice is option C
The proportion of green marbles to red marbles is 3: 1
Step-by-step breakdown:
According to the problem statement:
A bag holds 44 marbles, comprising both red and green ones.
⇒Total marbles = 44
If it includes 11 red marbles.
Then;
Green marbles = Total marbles - red marbles.
By substituting the values provided,
Green marbles = 44 - 11 = 33
We are tasked with determining the ratio of green marbles to red marbles.
Consequently, the ratio of green to red marbles is 3: 1
