Find the quotient. 5 1/4 - 15

a. 7/20
b. 78 3/4
c. 2 6/7
d. 3 1/4

Answers

Answer 1

What I find helps me with division is turning fractions into decimals. In this case 5 1/4 becomes 5.25 and 5.25/15 is .35 (equivalent to 7/20) Answer A: 7/20

Answer 2

The answer should be C- 2 6/7

I believe the question you are asking is what 5 1/4 (otherwise known as 5.25) divided into 15 is.

Simply put, your question is 15 divided by 5.25 (or 5 1/4)

To solve this we can make the fraction 5 1/4 into an improper fraction. This makes the fraction to consist of a numerator and a denominator and no whole numbers. Converting 5 wholes into fourths would mean 5 times 4 which is 20. Therefore 5 converted into 1/4 ‘s is 20 1/4’s. This combined with the other 1/4 in the fraction 5 1/4 makes the improper fraction 21/4.

When you divide fractions you switch the numerator and denominator of the fraction on one side (usually the right side although it doesn’t matter as long as you only switch one fraction of the two) and multiply. 15 times now 4/21 is 60/21.

To simplify this you can divide the numerator and denominator by a common factor. We can start with 3, simplifying the fraction to 20/7. Now as you may notice in the answer choices they are all mixed numbers, consisting of a whole number as well as the numerator and denominator. 20/7 as a mixed number is 2 6/7 as you can have 2 times 7 (14) and then have 6 left so you have 2 wholes and 6/7 away from another whole. This makes C the answer

Answer:

d. 3x + 6 = 26

Step-by-step explanation:

Definitions

Integer: a whole number that can be positive, negative or zero.
e.g. ..., -3, -2, -1, 0, 1, 2, 3, ...Even number: an integer that is exactly divisible by two. For example, 2, 4, 6, 8 are all positive even numbers.Consecutive: following one after the other in order.

The sum of three consecutive even integers

Let x be the first even integer.

As there is a difference of 2 between consecutive even integers, the next even integer after x will be (x + 2).

Therefore, the next even integer after (x + 2) will be (x + 2) + 2 = (x + 4).

So "the sum of three consecutive even integers is twenty-six" is:

x + (x + 2) + (x + 4) = 26

To solve

⇒ x + (x + 2) + (x + 4) = 26

⇒ x + x + 2 + x + 4 = 26

⇒ 3x + 6 = 26

(Please note that there are no three consecutive even integers that sum to 26, so the problem cannot be solved).

the answer to the question is d.

John has decided to prepare an old field for his son's new horse. the length of the field is 10 meters less than 4 times its width. He will spend $1,584 on fencing for the field at a cost of $4.80 per meter. He also needs to buy sweetgrass seed to plant in the field. The seed costs $3.98 per bag and each bag covers 460 square meters. If John has $1,600, is this enough money to purchase the fence and all the seeds needed to plant in this field?

Answers

Answer: The total money invested in the field will be $1,623.80

Step-by-step explanation:

step 1

Find the dimensions of the field

Let

x -----> the length of the field

y -----> the width of the field

p=2(x+y)

p(4.80)=1,584

p=330m

we know that

The perimeter of the field is equal to

330=2(x+y)----> equation A

x=4y-10 ------> equation B

substitute equation B in equation A and solve for y

330=2(4y-10+y)

165=(5y-10)

5y=165+10

y+35

Find the value of x

x=4(35)-10+130

therefore

The length of the field is 130 meters and the width of the field is 35 meters

step 2

Find the area of the field

The area of the field is

A=xy

substitute

A=(130)(35)=4,550m2

step 3

Find the number of bags of seed

Divide the area by 460

4,550/460=9.89 bags

Round up to the nearest whole number

9.89 bags=10 bags

step 4

Find the cost of the seed

(10 )(3.98)=$19.8

step 5

Find the total money invested in the field

1,584+$39.8=$1,623.80

b. x + (x + 2) + (x + 4) = 39

Step-by-step explanation:

Definitions

Integer: a whole number that can be positive, negative or zero.
e.g. ..., -3, -2, -1, 0, 1, 2, 3, ...Odd number: an integer that when divided by two leaves a remainder (so not a multiple of 2). For example, 1, 3, 5, 7 are all positive odd numbers.Consecutive: following one after the other in order.

The sum of three consecutive odd integers

Let x be the first odd integer.

As there is a difference of 2 between consecutive odd integers, the next odd integer after x will be (x + 2).

Therefore, the next odd integer after (x + 2) will be (x + 2) + 2 = (x + 4).

So "the sum of three consecutive odd integers is thirty-nine" is:

x + (x + 2) + (x + 4) = 39

To solve

⇒ x + (x + 2) + (x + 4) = 39

⇒ x + x + 2 + x + 4 = 39

⇒ 3x + 6 = 39

⇒ 3x = 33

⇒ x = 11

Therefore, the three consecutive odd numbers are 11, 13 and 15.

Answers

Total bill is $140.30

Mr. Rodriguez's bill after receiving a discount of 12 1/2% on each item is $140.30.

To calculate Mr. Rodriguez's bill after receiving a discount of 12 1/2% on each item, we need to find the discounted price for each item and then add them together to get the total bill.

First, let's calculate the discount for each item:

Jacket: 12.5% of $69.50

Discount on jacket = 12.5/100 * $69.50 = $8.69

Tie: 12.5% of $15.50

Discount on tie = 12.5/100 * $15.50 = $1.94

Raincoat: 12.5% of $75.35

Discount on raincoat = 12.5/100 * $75.35 = $9.42

Now, subtract the discounts from the original prices to get the discounted prices for each item:

Jacket price after discount = $69.50 - $8.69 = $60.81

Tie price after discount = $15.50 - $1.94 = $13.56

Raincoat price after discount = $75.35 - $9.42 = $65.93

Finally, add the discounted prices of all items to find the total bill:

Total bill = $60.81 + $13.56 + $65.93 = $140.30

3 friends shared 48 pineapples equally among themselves. One of the friends sold all his pineapple each at $5 how much did he get from selling the pineapples?

Answers

Answer: $80

Step-by-step explanation:

Step 1: Find how much each person got

48 pineapples shared amongst 3 people

48÷3= 16 pineapples each

Step 2: Find how much he earned

16 pineapples for $5 each

Total money made: 16x5= 80

$80 in all selling his share of the pineapples

hope this helps!!

The total amount of money the friend made from selling his pineapples is $80

How much did he get from selling the pineapples?

Total pineapples = 48

Total friends = 3

Number of pineapples each friend takes = Total pineapples / Total friends

= 48/3

= 16 pineapples per friend

Cost of each pineapple = $5

Total amount the friend made from selling his pineapples = Cost of each pineapple × Number of pineapples each friend takes

= $5 × 16

=$80

Hence, the friend made $80 from selling his pineapples.
