Solve each system by elimination. 3x - 2y = 1 2x + 2 y = 14

Answers

Answer 1

Add 3 and 12 , cancel -2 y+2y and and add 14 and 14
3x-2y=14
12x+2y=14
15x=28
Divide both sides by 15
X=28/15
3x 28/15 -2y=14
Y=-21/5
(X,y)=28/15, -21/5
3x 28/15 -2x(-21/5)=12x 28/15 +2x(-21/5)=14
14=14=14
(x, y)=(28/15, -21/5) is the answer

Leyan bought 234 pounds of apples for $1.32 per pound, 112 pounds of peaches for $1.20 per pound, and some tomatoes, all from a grocery store. The total cost of his purchase was $9.63. How much money did Leyan spend on tomatoes?

Answers

Answer: See explanation

Step-by-step explanation:

I think your question isn't well written and that 234 was meant to be 2.34 and 112 was meant to be 1.12

Let the amount spent on tomatoes be x.

The information given in the question can then be used to form an equation as thus:

Apples + Peaches + Tomatoes = $9.63

(2.34 × $1.32) + (1.12 × $1.20) + x = $9.63

$3.0888 + $1.344 + x = $9.63

x = $9.63 - ($3.0888 + $1.344)

x = $9.63 - $4.4328

x = $5.1972

The amount spent on tomatoes will be $5.1972

Answer:

The answer is 4.2 I did this question already

Step-by-step explanation: You multiply 2 3/4 and 1.32 and then add that to the product of the 1 1/2 peaches for 1.20 per pound, then subtract the answer from 9.63 to get the solution for x.

Principal = $2,400
Rate = 4%
Time = 30 months

Answers

Answer:

$240

Step-by-step explanation:

I = prt

I = (2,400) (0.04) (2.5)

note: I changed 4% to a decimal and 30 months to 2.5 years

I = 96 (2.5)

I = 240 <-- The interest

The simple interest accumulated on a principal of $ 2,400.00 at a rate of 4% per year for 2.5 years (30 months) is $240.00.

if y=3 then 14y equals

Answers

Answer:

Step-by-step explanation:

14(3)

Answer:

Step-by-step explanation:

first, substitute 3 for y in 14y. 14y means you are multiplying 14 and y, so when you plug in 3 for y, you're multiplying 14 and 3! :)

14y ⇒ 14(3)

simplify by multiplying 14 · 3.

14(3) = 42

so, when y = 3, 14y = 42.

you can check the answer by solving for y in 14y = 42.

divide both sides of the equation by 14.

14y/14 = 1y or y42/14 = 3

after dividing, you're left with y = 3. that means 14y does indeed equal 42 when y = 3! :)

The sum of three consecutive numbers is
42. Find the largest number in the set

Answers

Answer:

Step-by-step explanation:

Well consecutive numbers mean that the 3 numbers will follow each other in smallest to largest.

Example : 6, 7, 8 or 6,34,87

Non-Example : 7, 9, 6

As long as the number is greater than the one before it they are consecutive.

Following this rule I have come up with the numbers :

10, 12, 20

These three numbers are consecutive and equal to 42.

Now to find the largest number in this set just look at the greatest value which would be 20.

I don't have an entire explanation for this as I just did it in my head but I do hope it is correct.

Suppose both factors in a multiplication problem are multiples of 10. Why might the number of zeroes in the product be different than the total number of zeroes in the factors?

Answers

Answer:

Multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.

Step-by-step explanation:

Let the first five multiples of ten be

10*1= 10

10*2= 20

10*3=30

10*4=40

10*5= 50

Suppose we chose 20 and 50.

Now multiplying 20 with 50 we get

20*50= 1000

IF we count the total number of zeros in the factors ( 20 and 50) they are 2.

But the number of zeros in the product (1000) are 3.

This is because when we multiply 2 with 5 we get 10 which adds to the existing number of zeros ( i.e 2) and we get a total of 3 zeros.

And multiplying 10 with 50 we get

10*50= 500

IF we count the total number of zeros in the factors ( 10 and 50) they are 2.

But the number of zeros in the product (500) are also 2.

This is because when we multiply 1 with 5 we get 5 which does not add to the existing number of zeros ( i.e 2) and the total number of zeros remain the same.

Similarly multiplying 20 with 30 we get

20*30= 600

IF we count the total number of zeros in the factors ( 20 and 30) they are 2.

But the number of zeros in the product (600) are also 2.

This is because when we multiply 2 with 3 we get 6 which does not have a zero and the total number of zeros remain the same as in the factors.

So we see that multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.

I know what you're thinking. No way, right? English class is the most boring class of the day, right? I mean, why do I need to take English class when I already speak English? Right? Yeah, well I felt that way, too, until last summer when English class literally saved my life. Let me explain. My foster family, the Jamesons, decided to take a vacation. Sounds great, huh? Maybe Disneyland or a week on the beach? No way. They wanted to go to the desert. Long story short, we drove half way across the country to camp out in the Great Basin Desert. "Josh, be sure to pack your warmest clothing," Mrs. Jameson yelled up the stairs. "The desert is cold at night, but don't worry. It won't leave you cold. Just wait until you see the stars." We finally arrived at the Great Basin National Park, and I have to admit it was different than I imagined. "Amazing, isn't it?" Mr. Jameson asked me as we looked out over the desert's vast, silent valleys. I just grunted back at him and put my earphones back in. No matter what changed in my life, no matter how many times I failed, my music was always there. Later that night, I sat inside my tent and listened to the Jamesons telling stories around the fire they made. They thought it was so easy. Telling stories. Reading stories. I couldn't even pass English class. I couldn't understand those stu*** stories. Suddenly angry, I left the tent. They didn't even notice. The air was colder, but the stars were amazing. I had to admit it. I turned off my music as I walked and listened to the desert. Coyotes howling. Owls hooting. Clawing. Scurrying. Something wet hit my face. I looked up and realized it was snowing! In the desert in July! And I was lost. I wandered for hours but couldn't find our camp. The temperature continued to drop. I found a tree with deep crevices in the trunk and took shelter. My hands were getting numb, and I knew I was in trouble. Then I remembered Jack London and his story that we read in English class, "To Build a Fire." I knew I needed to keep warm, so I gathered up the branches around the base of the tree, piled up some dry grasses for kindling, and used the matches in my pocket to get the fire going. Just like in Jack's story. It worked! I spent the night keeping that fire going and listening to the sounds of the desert. In the morning, the Jamesons found me. I was only about a half-mile away. "Look at you," Mrs. Jameson said, when I told her how I'd remembered that story from English class, "making use of those 'stu***' stories from English class. Now all you have to do is write your own because your friends aren't going to believe how English class saved your life!"How does the setting affect Josh? A. It makes him cry because he is afraid of the dark. B. It allows him time to be alone and reflect. C. He becomes irritable because of the intense heat. D. The desert is so hot that he drinks more water. what is the answes please I need it! HELP MEH PLEASE!!!!!!!!!!!!!!!!!!
