distribute

64x + 48 = -6x -22

get rid of the smallest x by adding 6x to both side

minus 48 to both sides

70x = -70

divide both side by 70

yes it is because you find the LCM which is 48 so then you convert those 2 fractions to have a denominator of 48 so 7/12 becomes 28/48. next you change 9/16 which becomes 27/48. now your equation would be 28/48>27/28

In a survey of 160 people who have reptiles as pets, 40% have a pet snake. Of those with a pet snake, 25% also have a pet lizard. Of those who do not have a pet snake, 75% have a pet lizard.
Part A

Part B
What percentage of those surveyed have a pet lizard?
Part C
What percentage of those surveyed have both a snake and a lizard?

Answers

Part a is the answer

Percentage of people having Lizard = 55% , Percentage of people having both Lizard & Snake = 10%

Important Information : Percentage people having pet snake = 40%

C] Percentage people having pet lizard, along with pet snake = 25% of those having pet snake = 25% of 40% = 10% {Percentage of people having both snake & lizard)

Percentage of people having pet snake only = 75% of those who don't have snake = 75% of ( total - 40%) = 75% of 60% = 45%

B] Total percentage of people having pet lizard = 10% + 45% = 55%

Answers

Answer:

x/3.5h = -$1.4

So, x = -$1.4 * 3.5h

= -$4.9

Step-by-step explanation:

Since your losing $1.4 every hour, the 1.4 is supposed to negative.

Also, since your losing that amount of money for 3.5 hours, we are trying to find the total of how much money is lost in the 3.5 hours. To do this, we have to do x/3.5h = -$1.4. But since you can't do x/3.5, we have to do inverse operation. When you divide 3.5 hours to the other side of the equation it becomes multiplication. So you do -$1.4 times 3.5 hours

and get  -$4.9.

1. 6/15, or 2/5.

2. Apples cost more per pound.

Step-by-step explanation:

1. Brian reads 2/15 in 20 minutes, like we were told. It's easy to determine how much of his book he can read within an hour, by using the ratio 1/15:10. There's clearly 1/15 in 10 minutes, 2/15 in 20, 3/15 in 30, and so on. This would result in him reading 6/15's of his book in an hour.

2.

Peaches

0.6÷8/5 converts to .6 × 5/8. The result is .375.

Apples

1.75 ÷7/2 converts to 1.75×2/7. The result of this equation is .5, so therefore, the apples cost more per pound.

8/15 because 2/15 *3 is 6/15 + 2 is 8 and you multiply by 3 because 60/20=3

Hey there!

In order to solve for this particular question that you have asked.. we can just simply divide 28 from 4

28 ÷ 4 / 4 ÷ 4

Finally, use decimal numbers to write an expression that represents the net change in Rylee’s bank account balance for her entire shopping trip. Use your answers from parts A through C to guide you.


PART C; The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:
-$23.50.

Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is
-$23.50 – (-$23.50 × 0.2).

Further simplify the expression by factoring -$23.50 from both terms:

-$23.50 – (-$23.50 × 0.2)
=
-$23.50(1 – 0.2)
=
-$23.50(0.8).

Answers

Answer:

look at explanation

Step-by-step explanation:

PART C; The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:

-$23.50.

Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is

-$23.50 – (-$23.50 × 0.2).

Further simplify the expression by factoring -$23.50 from both terms:

-$23.50 – (-$23.50 × 0.2)

=

-$23.50(1 – 0.2)

=

-$23.50(0.8).

The net change to her banking account balance is $83.22.

What is net change?

The net change theorem states that when a quantity changes, the final value equals the initial value plus the integral of the rate of change. Net change can be a positive number, a negative number, or zero.

Given that, She spent $36.50 plus 8% tax.  (to calculate the tax amount, we have to multiply the cost by the percentage in decimal form)

36.50 x (8/100) =$2.92 (value of tax)

Adding to the original cost

36.50+2.92 = $39.42

Then, she spent $25 to refuel her car at the gas station.

39.42 +25 = $64.42

She bought groceries worth $23.50. At the grocery checkout, she handed over a coupon for a 20% discount on her purchase

23.50 x (20/100) = 4.7 (amount of discount)

Subtracting to the purchase

23.50 -4.7= $18.8

Hence, adding to the total cost.

64.42 +18.8 = $83.22

Undoubtedly the Indians perished in great numbers. Yet although European enslavement of Indians and the Spanish forced labor system extracted a heavy toll in lives, the vast majority of Indian casualties occurred not as a result of hard labor or deliberate destruction but because of contagious diseases that the Europeans transmitted to the Indians. The spread of infection and unhealthy patterns of behavior was also reciprocal. From the Indians the Europeans contracted syphilis. The Indians also taught the white man about tobacco and cocaine, which would extract an incalculable human toll over the next several centuries. The Europeans, for their part, gave the Indians measles and smallpox. (Recent research has shown that tuberculosis predated the European arrival in the new world.) Since the Indians had not developed any resistance or immunity to these unfamiliar ailments, they perished in catastrophic numbers.-- From The Crimes of Christopher Columbus by Dinesh D'Souza, 1995The author of this article believes that the Native American population declined greatly mostly because of A.enslavement, mistreatment, and hard labor.B.lack of immunity to some diseases.C.violent conflict.D.unhealthy patterns of behavior. 30 POINTS!!!!
