Let X = the number of weeks.
Jeanette will pass 3 per week, so 3x, and she already passed 8, so Jeanette would be 3x +8
Paul would be 4x + 3
Set them to equal to solve for x ( the number of weeks.)
3x +8 = 4x +3
Subtract 3x from both sides:
8 = x +3
Subtract 3 from both sides:
X = 5
So it will take 5 weeks to be the same.
Replace X with 5 to find the number of scales.
3x + 8 = 3(5) + 8 = 15 +8 = 23
They would have 23 scales.
Sofia's parents gave her an allowance for summer camp of $125.if she is going to be at camp for 6 weeks,what is the most she can spend each week while she is at camp? Inequality
Sofia can spend at most $20.83 each week.
Step-by-step explanation:
Given,
Amount of given by Sofia's parent = $125
Number of weeks = 6
Let,
x represent the amount that Sofia can spend each week.
As Sofia has $125, therefore, she can spend maximum $125 or less than that.
[tex]6x\leq 125[/tex]
Dividing both sides by 6
[tex]\frac{6x}{6}\leq \frac{125}{6}\\x\leq 20.83[/tex]

Olive Oil costs $8.70 per liter. A restaurant owner buys 5.6 liter of olive oil. How much does the owner pay?
Answer:
$48.72
Step-by-step explanation:
5.6 liters x $8.70 per liter= $48.72 total cost
Final answer:
To determine the total cost of the olive oil, multiply the quantity of 5.6 liters by the price per liter, which is $8.70. The total cost for the restaurant owner is $48.72.
Explanation:
The question asks us to calculate the total cost for a restaurant owner who buys 5.6 liters of olive oil at a price of $8.70 per liter. To find the total cost, we multiply the quantity of olive oil by the price per liter.
Calculation: Total cost = Quantity x Price per liter
Total cost = 5.6 liters x $8.70 per liter
Total cost = $48.72
Therefore, the restaurant owner will pay $48.72 for 5.6 liters of olive oil.
A researcher conducted a study investigating the effect of computer screen time on a person’s amount of REM sleep. The researcher randomly assigned 100 people into four groups. The first group was given 2 hours of computer screen time each day, the second group was given 4 hours each day, the third group was given 6 hours each day, and the fourth group was given 8 hours each day. The study was conducted for one week, and the amount of REM sleep for each person was measured. What is the explanatory variable in the study?
Answer:
Amount of screen time
Step-by-step explanation:
Explanatory variables are those variables that are not totally independent and are used to predict or explain differences in the response variable.
Having pointed what an explanatory variable is, we'll list the explanatory variable(s) in the question, using the definition above.
The Variable used to predict results here is the amount of screen time.
In that case, it is the explanatory variable.
And it's of numerical type.
In the described study, the explanatory or independent variable is the amount of computer screen time each day, as it is the variable that is being manipulated by the researcher in order to examine its effect on REM sleep.
Explanation:In this particular research study, the explanatory variable, or the independent variable, is the amount of computer screen time each day. This is because the explanatory variable is the factor manipulated by the researcher to observe any potential effects on the outcome variable, which in this case, is the amount of REM sleep.
The participants were divided into four different groups, each exposed to a different amount of screen time: 2 hours, 4 hours, 6 hours, and 8 hours. These varying hours of exposure were purposely manipulated by the researcher to observe and measure any differences in the REM sleep duration. Therefore, the computer screen time is the explanatory variable or cause, and the observed alterations to the REM sleep will be the response, or the dependent variable.

First find m<HGC.
m<HGC=14 degrees (through vertical angles)
So...
m<HGE=14+78=92 degrees (through adjacent angles)
Now we have two parallel line cut by a transversal. And so... <HGE and <CEG are same side interior angles which means they are supplements (sum to 180 degrees)
m<HGE+m<CEG=180
92+m<CEG=180
m<CEG=88 degrees
<CEG and <CEB make a linear pair and are thus are supplements as well.
So...
m<CEG+m<CEB=180
88+m<CEB=180
m<CEB=92 degrees
m<CEB=4x=92
x=92/4=23 degrees
answer: 23 degrees

Michael and Alexandra left their home at 8:00am to drive to new york. Michael drove at 55 miles an hour and arrived at 5:00 pm. Alexandra drpvw at 45 miles an hour and arrived at the same place as Michael. At what time did Alexandra arrive?
Answer:
7:00 pm
Step-by-step explanation:
You want to know Alexandra's arrival time if she started at the same time as Michael (8:00 am) and drove at 45 mph, while Michael drove at 55 mph and arrived at 5:00 pm.
TimeTravel time is inversely proportional to speed, so the time it takes Alexandra to make the trip is 55/45 = 11/9 times what it take for Michael to make the trip.
Michael's travel time from 8 am to 5 pm is 9 hours, so Alexandra's travel time is ...
(11/9)(9 h) = 11 h
She will arrive 2 hours after Michael does.
Alexandra arrives at 7:00 pm.

a bucket hold b liters of water, but a jar holds 8fewr liters than the bucket. how many times more water can the bucket hold than the jar?
Final answer:
To find how many times more water the bucket can hold than the jar, divide the bucket's capacity by the jar's capacity.
Explanation:
The bucket holds b liters of water, and the jar holds 8 fewer liters than the bucket. To find out how many times more water the bucket can hold than the jar, we need to compare their capacities. \
The bucket's capacity is b liters, and the jar's capacity is b - 8 liters.
To find the ratio of the bucket's capacity to the jar's capacity, we divide the bucket's capacity by the jar's capacity:
b / (b - 8)This ratio represents how many times more water the bucket can hold than the jar.
Katie Made a scale drawing of a restaurant in real life the restaurant kitchen is 12 m wide it is 36 mm wide in the drawing what scale katie use for the drawing?
Answer:
Scale : 1 mm = [tex]\frac{1}{3}\ m[/tex]
Or
Scale : 3 mm = 1 m
Step-by-step explanation:
Let the scale used be 1 mm = 'x' m
Given:
Actual width of kitchen is 12 m.
Length used by Kate in drawing is 36 mm.
So, 36 mm in drawing is equivalent to 12 m in actual.
Therefore, 1 mm in drawing is equivalent to 'x' m in actual.
Taking proportions and solving by cross multiplication, we get
[tex]\frac{36}{12}=\frac{1}{x}\\36x=12\\x=\frac{12}{36}\\x=\frac{1}{3}\ m[/tex]
Therefore, 1 mm in drawing is equal to [tex]\frac{1}{3}\ m[/tex] in actual.
Scale : 1 mm = [tex]\frac{1}{3}\ m[/tex]
Or
Scale : 3 mm = 1 m
2x=(360÷4) solve for x.
Answer:
Step-by-step explanation:
2x=(360÷4)
2x = 90
Dividing by 2
x = 90/2
x = 45
By following the steps of simplifying, isolating, and solving for x, we find that x = 45 is the value that satisfies the given equation.
To solve the equation 2x = (360 ÷ 4) for x, we need to isolate x on one side of the equation. Follow these steps to find the value of x:
Step 1: Simplify the expression on the right side of the equation.
360 ÷ 4 = 90
Step 2: Replace the right side of the equation with its simplified value.
2x = 90
Step 3: To isolate x, divide both sides of the equation by 2.
(2x) ÷ 2 = 90 ÷ 2
This simplifies to:
x = 45
The solution to the equation is x = 45. To verify, you can substitute x = 45 back into the original equation:
2(45) = 90
90 = 90
Since both sides of the equation are equal, x = 45 is indeed the correct solution.

Tim's phone service charges $25.08 plus an additional $0.22 for each text message sent per month. If Tim's phone bill was $30.58, which equation could be used to find how many text messages, x, Tim sent last month?
Final answer:
To find how many text messages, x, Tim sent last month, use the equation: Total cost = fixed cost + variable cost. Given that Tim's phone bill was $30.58, the equation is $30.58 = $25.08 + $0.22x. Solving the equation gives x ≈ 25, so Tim sent approximately 25 text messages last month.
Explanation:
To find the number of text messages, x, Tim sent last month, we can use the equation:
Total cost = fixed cost + variable cost
Given that Tim's phone bill was $30.58, the fixed cost is $25.08. The variable cost is $0.22 per text message sent. Let's represent the number of text messages sent by x.
So, the equation becomes:
$30.58 = $25.08 + $0.22x
To solve for x, we need to isolate x. Subtract $25.08 from both sides of the equation:
$30.58 - $25.08 = $0.22x
Simplify:
$5.50 = $0.22x
Divide both sides of the equation by $0.22:
x = $5.50 / $0.22
x ≈ 25
Therefore, Tim sent approximately 25 text messages last month.
