The general form of the linear equation is,
y = mx + b

where y is the dependent variable, m is the slope, x is the independent variable, and b is the y-intercept.

Substituting the known values,

1. y = 2.6x

where y is the total cost and x is the number of gallons purchased.

2. y = 1.6x + 2

where y is the total weight of the bucket and the golf balls and x is the number of golf balls inside the bucket.

3. P = 2x - (110/150)(x)

Simplifying,

P = 19x/15

where P is the profit and x is the number of pounds of tomatoes brought to the market

4. y = 40x + 80

where y is the total number of enrolled students and x is the number of years

5. y = mx + b

where y is the total number of charge, m is the cost per person, x is the total number of persons and b is the flat fee

The ratio of the perimeters of two similar triangles is 4:3. What are the areas of these triangles if the sum of their areas is

emmasim [6.3K]

Answer:

the areas of these triangles are 83.2cm² and 46.8cm²

Step-by-step explanation:

1. If the triangles are similar and the ratio of the perimeter ois 4:3, then the areas are in the following ratio:

4²:3²

16:9

2. The sum of their areas is 65 cm², then, you can calculate the area of the larger triangle as following:

130(16/16+9)

130(0.64)

=83.2cm²

3. The area of the smaller triangle is:

130(9/16+9)

130(0.36)

46.8cm²
