Multiply the first equation by –3.
Multiply the second equation by 2.
Add the resulting system of equations.

Which terms will cancel when you add the resulting system of equations?

Answers

Answer 1

The first equation will turn into -18x -6y = -18, and the second equation will turn into 14x + 6y = 18. The y terms will cancel out when you add the equations together.

Answer:

x = -4

Step-by-step explanation:

First you need to find the common factor, which in this problem is 3. Then you need to divide the equation by the common factor which makes it -x = 4. We then need to multiply the equation by -1 to make x positive which makes it x = -4.

Find the area of this parallelogram.
9 cm
12 cm
1
21 cm

Answers

The area of the given parallelogram with a base of 12 cm and a height of 9 cm is 108 cm². The area is obtained by multiplying the base and height.

To find the area of a parallelogram, the formula that should be used is A = b × h, where b is the base and h is the height. Since a parallelogram has two pairs of parallel sides, either of the two parallel sides can be chosen as the base. The height is the perpendicular distance between the base and the opposite side.

In the given parallelogram, the base is 12 cm since it is one of the parallel sides. The height, on the other hand, is 9 cm since it is the perpendicular distance between the base and the opposite side. Therefore, the area of the parallelogram is: A = b × h = 12 cm × 9 cm = 108 cm²

Thus, the area of the parallelogram is 108 cm². It is important to note that the unit of the area is always squared since the area is calculated by multiplying two lengths together.

Answer:

Train B is traveling faster.

Step-by-step explanation:

To find which train is faster, divide the distance the train traveled by the elapsed time for each train:

Train A:

Distance traveled is 12.5 meters.

Elapsed time is 1 second.

12.5 ÷ 1 = 12.5

Train A travels 12.5 meters per second.

Train B:

Distance traveled is 100 meters.

Elapsed time is 4 seconds.

100 ÷ 4 = 25

Train B travels 25 meters per second.

25 is greater than 12.5, so train B travels faster.

On those rare occasions when he did, he never used more words than what was needed. As a result, I did not benefit from a first-hand account of the Cultural Revolution. Instead, I was forced to gather information from other sources. But that wasn't good enough for me. I wanted to hear it from him. We left our country for America when I was just a child. I never knew if my father had worked in the revolution as a peasant, solider, or a revolutionary intellectual. I tried to picture him writing big-character posters and holding great debates with his fellow revolutionaries. Did he use big words? Did he sometimes skip classes to meet with the comrades across China? These were questions I often asked myself. I wanted to ask him if he believed that the right to air one's views fully really existed in his youth. As an only child, who was brought up to think that education was my only key to prosperity, I didn't know why my father did not finish his degree. My father's friends behaved just like himquiet, laborious, and mysterious. They all looked at me with eyes full of love and hope. Only once, did I hear one of them speak about the past. Uncle Chen recounted something about "not being a Communist," "arrest," and "freedom." It was then that I realized my parents and their friends had always talked to each other in Mandarin, the language I could no longer grasp, when they spoke about their lives back home. At that moment, I regretted my dwindling Chinese vocabulary and the opportunities I had already missed. 9 Based on this excerpt, the Cultural Revolution in China A. provided safety for people who didn't support communism. B. encouraged all citizens to be involved in changing the nation. C. discouraged the citizens from holding meetings and debates. D. demanded that the revolutionaries move to other countries. Which statement describes the point of view of The Adventures of Tom Sawyer? A. A narrator is telling the story. B. A family member is telling the story. C. Sid is narrating the story. D. Tom is narrating the story.Text:Monday morning found Tom Sawyer miserable. Monday morning always found him sobecause it began another week's slow suffering in school. He generally began that day with wishing he had had no intervening holiday, it made the going into captivity and fetters again so much more odious. Tom lay thinking. Presently it occurred to him that he wished he was sick; then he could stay home from school. Here was a vague possibility. He canvassed his system. No ailment was found, and he investigated again. This time he thought he could detect colicky symptoms, and he began to encourage them with considerable hope. But they soon grew feeble, and presently died wholly away. He reflected further. Suddenly he discovered something. One of his upper front teeth was loose. This was lucky; he was about to begin to groan, as a "starter," as he called it, when it occurred to him that if he came into court with that argument, his aunt would pull it out, and that would hurt. So he thought he would hold the tooth in reserve for the present, and seek further. Nothing offered for some little time, and then he remembered hearing the doctor tell about a certain thing that laid up a patient for two or three weeks and threatened to make him lose a finger. So the boy eagerly drew his sore toe from under the sheet and held it up for inspection. But now he did not know the necessary symptoms. However, it seemed well worth while to chance it, so he fell to groaning with considerable spirit. But Sid slept on unconscious. Tom groaned louder, and fancied that he began to feel pain in the toe. No result from Sid. Tom was panting with his exertions by this time. He took a rest and then swelled himself up and fetched a succession of admirable groans. Sid snored on. Tom was aggravated. He said, "Sid, Sid!" and shook him. This course worked well, and Tom began to groan again. Sid yawned, stretched, then brought himself up on his elbow with a snort, and began to stare at Tom. Tom went on groaning. Sid said: "Tom! Say, Tom!" [No response.] "Here, Tom! TOM! What is the matter, Tom?" And he shook him and looked in his face anxiously. how do I figure out the speed of a train with constant speeds Do you think that humans and humpback whales share a common evolutionary lineage?
