Jay simplified the expression -3 × (3 + 12 ÷ 3) - 4. For his first step, he added 3 + 12 to get 15. What was Jay’s error?

Answers

Answer:

He should have divided 12 ÷ 3 first.

Step-by-step explanation:

Following PEMDAS/BODMAS, the first step is solving equations in parentheses. Since the parentheses contain a multi-step equation, Jay needs to follow PEMDAS for inside the parentheses as well. Instead of adding 3+12 first, he should have done division first (12  ÷ 3).

How the problem should be solved:

-3 × (3 + 12 ÷ 3) - 4

-3 × (3 + 4) -4

-3 × 7 - 4

-21 - 4

Sam already has $50 dollars saved.

He wants to get $30 each week.

The cost is $410.

If he already has 50 you should subtract this from 410(it equals 360)

Answer:

8000 in³ because 20 × 20 × 20 is 8000

Answer and Step-by-step explanation:

We are given:

Each side of the box is 20 inches.

A side of the box is denoted as s.

The volume of a cube is [tex]V=s^{3}[/tex]

If s is a side of the box, and one side of the box is 20 in., then that means s is equal to 20.

So, to find the volume, we plug 20 in for s in the volume equation.

[tex]V = 20^{3}[/tex]

(This is the same as saying 20 times 20 times 20).

V = 8,000 [tex]in^{3}[/tex]

Help, Missing work!!!

Answers

Answer:

Step-by-step explanation:

11) add 20 to both sides, x=-3

12) divide both sides by -8, v=18

13) divide both sides by -7, n=19

14) multiply both sides by 9, n=171

Answer:

11. x= -3

12. v=8

13. n=19

14. n=171

Step-by-step explanation:

11. 20+3=23, but since the answer is negative, the 3 has to be negative (different signs = negative)

12. 144/8 = 8, since product is negative, the answer has to be positive (different signs = negative)

13. 133/7= 19, answer must be positive because product is negative (different signs= negative)

14. 9*19=171, so therefore 171/9=19

He standardized measures and coinage, kept records of granary storage and initiated an accounting that prevented tax evasion tax evasion being a threat to the state's growth. When the ruler of Qin died, Shang Yang was left without protection at court, and jealous persons at court had Shang Yang executed. But his work lived on. In 314 BCE twenty-four years after the death of Shang Yang the kingdom of Qin won a military victory over nomads to its north. In 311, Qin expanded southward onto fertile plane against more nomadic people and defeated a state called Shu, and a Qin general, Zhang Yi, founded a new city, Chengdu. Other states were also expanding: Yan against so-called barbarians east of the Liao River, and Chu was expanding southward across the Yangzi River. War and conquest reduced the number of states to eleven. One of the eleven, Wei, had been reduced as a power by its war against Qi (pronounced chi). Qi appeared to be the dominant power, and Qin joined a coalition of four other states against Qi, which the allies of Qin feared more than they did Qin. Qi was well organized and densely populated relative to most other states. It was high in food production and had grown wealthy also from trade in iron and other metals, and, in 256 BCE, Qi absorbed Lu. Qin expanded into Zhou family territory, an area around Luoyang containing about 30,000 people and thirty-six villages. A Zhou prince counter-attacked, trying to claim the Zhou throne for himself. Qin's army defeated him, and this brought the great Zhou dynasty, dating from 1045 BCE, to an end, 256 BCE. In 246 BCE, Yong Zheng, the thirteen-year-old son of the ruler of Qin, succeeded his father. After sixteen years of rule, Zheng embarked upon the conquest of the remaining states that had been a part of Zhou civilization. According to Victoria Tin-bor Hui, the historian Mark Edward Lewis describes Qin, in his words, as having enjoyed "a splendid geographic situation... It was accessible from the East only through the Hangu Pass and from the southeast through the Wu Pass." And, writes Victoria Tin-bor Hui, Ralph D. Sawyer "similarly thinks that Qin occupied a 'virtually unassailable mountainous bastion'. " note11 In the wars that led to a unification of what had been Zhou civilization, armies of hundreds of thousands were involved on both sides. Qin was driven by the fear that if it didn't defeat all of the others they would combine and crush it. Qin defeated one state after another: Han in the year 230, Zhao in 228, Wei in 225, the large but more sparsely populated and less tightly knit Chu in 223, Yan in 222 and Qi in 221. Occasionally, to eliminate possible military opposition, Qin's armies slaughtered all enemy males of military age. The Warring States Period was over. Zheng had become ruler of all that had been Zhou civilization. He went to a sacred mountain, Dai Shan, where, it would be said, he received the Mandate from Heaven to rule the "entire world." He took the name Shihuang-di (di signifying emperor). He was also named Qin Shi Huang. He then expanded his frontiers southward to Guangzhou and to Guangxi, creating what would thereafter be considered China. And he pushed into Annam, or northern Vietnam an area the Chinese would hold only temporarily. Shihuangdi had become the first emperor of China.Describe Zheng's position and the effects of his actions after the "period of Warring States".Describe Liu Bang's view of government during the Han Dynasty.
