Answers

Answer 1
Answer:

we know that

A store has apples on sale for $3.00 for 2 pounds

Part a) How many pounds of apples can you buy for $9?

by using proportion

(3)/(2)(usd)/(pound) =(9)/(x) (usd)/(pound) \n \n 3x=9*2\n \n x=(18)/(3) \n \n x=6 pounds

therefore

the answer Part a) is

6 pounds

Part b) If an apple is approximately 5 ounces, how many apples can you buy for $9?

we know that

1 pound=16 ounces

step 1

convert ounces to pounds

1apple=(5)/(16)pounds

by using proportion

(1)/((5)/(16))\ (apples)/(pounds) =(x)/(6) (apples)/(pounds)\n \n x(5)/(16) =6\n \n x=(16*6)/(5) \n \n x=19.2 apples

therefore

the answer part b) is

about 19 apples
Answer 2
Answer: Since 2 pounds is $3 and you have $9, you would do: 

(3)/(2) = (9)/(x) , x= # of pounds of apples

You do cross multiplication to get:

3x=18

x=6      

1 lb= 16 oz

So 6*16=96   to get the number of ounces you can buy for $9.

Then divide 96 by 5, so that is ABOUT 19 APPLES.

Can some one plz Solve this. 4 - 2x = 10

Answers

Answer:

x = -3

Step-by-step explanation:

Given the expression

4 - 2x = 10

Using the subtraction property of equality

We have ,

-2x = 10 - 4

OR subtract four from both sides of the equation

4-4 - 2x = 10 - 4

-2x = 6

Now, divide both sides by -2 to get the unknown x.

We have -2x/-2 = 6/-2

Therefore x = -3
