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!

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 = ___
Answers
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?
Answers
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).

108 is 36% of what number? Write and solve a proportion to solve the problem.
Answers
108/n = 36/100
Next write the cross products. So, 36n = 108 x 100 = 10,800
divide each side by 36.
36n/36 = 10,800/36
Lastly simplify. Which will be, n = 300.
so my answer is 108 is 36% of 300.
1. Take the percentage (36%) and change it to a decimal (.36)
2. Set up the equation.
.36x = 108
3. Divide both sides by .36
x = 300

Which of the following tables are non-linear?
Answers
PLEASE HELP ME :DDDDDDDDDDDDDD
Answers
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.
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?
Answers
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.
