The quired ratio of apple trees to pear trees is  7/3. Option A is correct.

Given that,
An orchard has 28 apple trees and 12 pear trees.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,
Number of apple trees = 28
Number of pear trees = 12
Ratio of apple to pear = 28 / 12
                                     = 7 / 3

Thus, the quired ratio of apple trees to pear trees is  7/3. Option A is correct.

Answer:

D. y=(3)/(2)x

Step-by-step explanation:

Answer:

find the actual discount, multiply the discount rate by the original amount 'x'. To find the sale price, subtract the actual discount from the original amount 'x' and equate this to given sale price. Solve the equation and find the original amount 'x'.

Step-by-step explanation:

Sale Price = $11.34 (answer). This means the cost of the item to you is $11.34. You will pay $11.34 for a item with original price of $12.60 when discounted 10%. In this example, if you buy an item at $12.60 with 10% discount, you will pay 12.60 - 1.26 = 11.34 dollars.

The markup from cost to sale price is 81 dollars.

Cost price, for instance, equals selling price plus profit ( when selling price and profit is given )

Cost is equal to Selling price plus Loss ( when selling price and loss is given )

The Cost price = 100 Selling Price + 100 + Profit

where the Selling Price and Profit Percentage are supplied.

The selling price of item = $390

cost = $270

10% × $390 = $39

Now subtract 39 from 390

390 - 39

351

Now subtract 270 from 351

351- 270

81

$81 is markup price .

Step-by-step explanation:

For a all you have to do is multiply by 3 so the answer would be -15

For b all you have to do is subtract 12 then divide by -1 so the answer would be -0.5

for c all you have to do is divide by -10 so the answer would be -0.1/-10 or 0.1/10

your answer is 17 kilometers :)

The actual distance between the two rivers is 17 Km.

Distance is a numerical or occasionally qualitative measurement of how far apart objects or points are.

Given that, the distance between two rivers on a city map is 8.5 cm. The scale on the map states that 3 cm represents 6 km.

Scale factor = 3/6 = 1/2

8.5*2 = 17

Hence, The actual distance between the two rivers is 17 Km

Answer: Finding the Inverse of a Function

First, replace f(x) with y . ...

Replace every x with a y and replace every y with an x .

Solve the equation from Step 2 for y . ...

Replace y with f−1(x) f − 1 ( x ) . ...

Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.

Step-by-step explanation:

Answer:

x=9

Step-by-step explanation:

x + x - 4 + x - 4 = 19

3x - 8 = 19

3x = 19 + 8

3x = 27

x = 9

Answer: x=9

Step-by-step explanation:

There are three sides 2 that are x-4 and 1 that is x. The equation would be

x+2(x-4)= 19 so you would simplify to get

X+2x-8=19 then 3x=27 then divide by three to get x=9
