Answer is B, there ya go.
Could someone help me quickly
Answer:
a) 9x + 7y = 279
3x + 5y = 135
b) X (Weight of each large box) = 18.75 kilograms
Y (Weight of each small box) = 15.75 kilograms
Step-by-step explanation:
Let's assume:
X is weight of each large box
Y is weight of each small box
First, multiply the opposite number to get the same value of y:
9x + 7y = 279 ..... ×5
3x + 5y = 135 ...... ×7
Second, here comes the outcome of the multiplication from both side:
45x + 35y = 1,395
21x + 35y = 945
24x = 450
x = 18.75 kg
if x = 18.75, then:
3x + 5y = 135
3×(18.75) + 5y = 135
56.25 + 5y = 135
5y = 135 - 56.25
5y = 78.75
y = 15.75 kg
If you try to input the x and y value into the part a) equation, then you will get the same total weight for first and second delivery respectively.
Hope it helps. Thanks!

A pet store specializes in exotic fish. The graph shows a proportional relationship between the number of fish and the number of fish tanks at the store. Fish 65 52 39 26 13 0 1 2 3 4 Fish Tanks 5 6 X The constant of proportionality shown in the graph in terms of the number of fish per fish tank is
Answer:
13
Step-by-step explanation:
if there are 5 tanks and 65 fish in all the tanks together, you take 65 and divide it by 5 to get 13 fish in each tank
: )
Answer:
10.84.
Step-by-step explanation:
To find the constant of proportionality, we can use the fact that the relationship between the number of fish and fish tanks is proportional. This means that the ratio of the number of fish to the number of fish tanks is always the same.
From the graph, we can see that when there are 65 fish, there are 5 fish tanks. When there are 52 fish, there are 6 fish tanks. Let's use these two data points to find the constant of proportionality:
The constant of proportionality = (Number of fish) / (Number of fish tanks)
For the first data point, we have:
65 / 5 = 13
For the second data point, we have:
52 / 6 = 8.67
We can see that these two values are not the same, which means that the relationship between the number of fish and the number of fish tanks is not exactly proportional. However, we can still find an average constant of proportionality between these two values:
(13 + 8.67) / 2 = 10.84
So the constant of proportionality, in terms of the number of fish per fish tank, is approximately 10.84.

Answer:
Step-by-step explanation:
To find the area of a rectangle, you multiply the length by the height.
First, we need to convert the mixed numbers to improper fractions:
Length: 6 3/4 ft = (6 x 4 + 3) / 4 ft = 27 / 4 ft
Height: 2 2/12 ft = (2 x 12 + 2) / 12 ft = 26 / 12 ft = 13 / 6 ft
Now we can calculate the area:
Area = Length x Height
Area = (27 / 4) ft x (13 / 6) ft
Area = 351 / 24 ft^2
Area = 14 11/24 ft^2
Therefore, the area of the rectangle is 14 11/24 square feet.

Which of the following tables are non-linear?
How does the fact that the points are on opposite sides of the y axis affect the process of finding the distance between the two points?
Answer:
See below.
Step-by-step explanation:
The fact that the points are on opposite sides of the y-axis does not affect the process of finding the distance between the two points. The distance between two points in a two-dimensional coordinate system can be found using the distance formula, which is based on the coordinates of the two points and does not depend on which side of the y-axis they lie. The distance formula is:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
where (x1, y1) and (x2, y2) are the coordinates of the two points, and d is the distance between them. The formula involves squaring the differences between the x-coordinates and the y-coordinates of the two points, and then taking the square root of the sum of the squares. The process remains the same regardless of which side of the y-axis the points are located.
The variables y and x have a proportional relationship, and y = 7 when x = 2.
What is the value of y when x = 5?
Enter your answer as a decimal in the box.
y = ___
Answer:
17.5
Step-by-step explanation:
x=2
y=7
when y by x, then multiple y by 5.
7/2= 3.5
3.5×5= 17.5
you can also do 7x2 which would give you 14 and then divide 7 by 2 to get 3.5, and add the two together, so 14+3.5=17.

What is the area of a right triangle with a height of 8.9cm and a base of 14.3cm?
Answer:
ar of triangke is 1 /2 base*height
so
ar = 1/2 * 8.9*14.3
ans = 63.63 sq cm
Answer: 63.63cm
Step-by-step explanation: To find the area for a triangle, the formula is A=L*W divided by 2. So you want to do A=14.3*8.9/2= 63.63500 (63.63).
