Answer:
It will take approximately 20.454545454545455 weeks for the amount of water in the two tanks to be the same.
Step-by-step explanation:
To find the number of weeks it will take for the amount of water in the two tanks to be the same, we can set up the following equation:
675 - 4w = 900 - 7w
Then, we can solve for w by adding 4w to both sides and then adding 7w to both sides:
11w = 225
w = 225 / 11
thus, It will take approximately 20.454545454545455 weeks for the amount of water in the two tanks to be the same.

A hook in an office storage closet can hold no more than 6 pounds. An order of jumbo paperclips weighs 2 pounds and an order of packing tape weighs 3 pounds. If x is the number of orders of paperclips and y is the number of orders of packing tape, which graph represents the overall equation represented by this scenario (all points may not apply to the scenario)?

On a coordinate plane, a solid straight line has a negative slope and goes through (0, 3) and (2, 0). Everything to the left of the line is shaded.
The first graph shows how many of each order could fit into a bag that was hanging from a hook. First, a detailed explanation: * Let's discuss the issue's solution.
Find graph?The quantity of orders of paperclips is x, and the weight of the order of jumbo paperclips is 2 pounds. The order of paperclips weighs 2 x = 2 x, the order of packing tape weighs 3 lbs., and the quantity of orders of packing tape is y. The weight of the tape order is 3 y = 3 y, the weight of the entire order is 2 x + 3 y, and the hook can only support a maximum weight of 6 y. 2x + 3y ≤ 6
The graph that depicts this inequality, Any line's equation is y = mx + c, where m represents its slope.
The y-intercept indicates to replace x in the equation by 0; the x-intercept indicates to replace y in the equation by 0; 2x - 3y 6 is the inequality. 2x + 3y = 6 is the equation for the line.
- Subtract 2x from both sides: 3y = 6 - 2x; - Divide both sides by 3: y = 6/3 - 2/3 x; - Locate the y-intercept: x = 0; y = 2;
The line crosses the y-axis at position (0 , 2)
– Locate the x-intercept.
∵ y = 0
∴ 0 = 2 - 2/3 x
- Adjust both sides by 2/3x.
∴ 2/3 x = 2
Increase both sides by 3.
Divide all sides by 2 to get the answer.
∴ x = 3
The line crosses the x-axis at position (3 , 0)

Find the coordinates of Triangle KLM after a translation to the right by 8 units, then a reflection across the x-axis. Show your work or explain what steps you take to find your answer.
The new coordinates of triangle KLM after the given translation is;
M'(6, 1)
L'(1, 4)
K'(4, 8)
How to find the coordinates of translation?In transformations, there are different types such as reflection, dilation, translation e.t.c
Now, translation is what we are dealing with here and translation is a rigid transformation which means that it does not alter the dimensions of the figure after transformation. Translation is just moving the object from one point to another.
In translation, the size, the shape and the orientation of the image remain the same as that of the original object. Thus, the same orientation means that the object and image are facing the same direction.
The given coordinates of the triangle are;
M(-2, 1)
L(-7, 4)
K(-4, 8)
Now, If you move horizontally 8 units to the right, it means that 8 is added to the x-coordinate of each of the vertices. Thus, the transformation rule here is;
(x, y) → (x + 8), y
Therefore the new coordinates of triangle KLM are;
M'(-2 + 8, 1) = M'(6, 1)
L'(-7 + 8, 4) = L'(1, 4)
K'(-4 + 8, 8) = K'(4, 8)

One week, Jayden earned $87.50 at his job when he worked for 5 hours. If he is paid
the same hourly wage, how many hours would he have to work the next week to earn
$105.00?
Answer:
Here answer
Step-by-step explanation:
To find the number of hours Jayden would have to work to earn $105.00, we need to first find his hourly wage. We can do this by dividing his total earnings by the number of hours he worked:
hourly wage = total earnings / number of hours worked
= $87.50 / 5 hours
= $17.50/hour
Now that we know Jayden's hourly wage, we can use it to find the number of hours he would have to work to earn $105.00. We can do this by dividing the total amount he wants to earn by his hourly wage:
number of hours = total earnings / hourly wage
= $105.00 / $17.50/hour
= 6 hours
Therefore, Jayden would have to work for 6 hours to earn $105.00 at his job.
