2(x+5)=3x+1
x=?
please solve

Answers

Answer:

x=9

Step-by-step explanation:

expand 2(x+5) : 2x+10

2x+10=3x+1

subtract 10 from both sides

2x+10-10=3x+1-10

simplify

2x=3x-9

subtract 3x from both sides

2x-3x=3x-9-3x

simplify

-x=-9

divide both sides by -1 (-1 is equal to -x or -1x)

-x/-1=-9/-1

simplify

x=9

hope this helps :) have a nice day !!

Answers

Answer:

I think its A

Step-by-step explanation:

I did the math and thats what i got even rounded up

The value of the expression 3.14 x 4 x 4 x 7 is  351.4 and for expression 3.14 x 7 x 7 x 4  is 615.4.

To round the expression to the nearest tenth, we need to evaluate it first. Let's calculate each expression:

3.14 x 4 x 4 x 7 = 351.36

3.14 x 7 x 7 x 4 = 615.44

Now, let's round each result to the nearest tenth:

Rounding 351.36 to the nearest tenth gives us 351.4

Rounding 615.44 to the nearest tenth gives us 615.4

Based on the given options, neither result matches exactly.

However, option A (124.6) is the closest rounded value to 351.4.

Answers

Answer:

90 miles.

Step-by-step explanation:

Knowing that an inch is equal to 40 miles you can take 40 and multiply it by 2 1/4, thus getting 90. Or, you can break it down. 2 times 40 equals 80. This leaves 1/4 inch left to figure out. If you divide 40 by 4 (figuring out a fourth) you would get 10. Add 80 and 10 and you would have 90 miles.

I think it will be 90

Melanie can run around the track 9 times in 28 minutes. At this rate, how many laps can she run in 1 hour and 15 minutes?

Answers

Step-by-step explanation:

First step is to identify what the problem is asking for and what is given.

9 laps in 28 minutes

Searching for number of laps in 1 hour and 15 min.

1 hour + 15 min. = 75 minutes convert to minutes

9 laps / 28 minutes = x laps / 75 minutes create an equation

9/28 = x/75

9*75 = 28x cross multiply

675 = 28x

x = 675/28 = 24.12 simplify

Melanie can run 24 complete laps in 1 hour and 15 minutes.

From the diary of a young girl by ann frank -4 3 + -7 ????????? DUE TODAY!!!!!!!!!!!!!!!!'How does this excerpt describe the Corrupt Bargain of 1824? Four major candidates ran in the 1824 election, all under the "Democratic-Republican" name. One of the candidates, Andrew Jackson, was already famous. In the 1780s, he earned the right to practice law and served in various offices of the state government, including senator. He earned the nickname "Old Hickory" for his toughness as a general during the War of 1812 and First Seminole War. Jackson supported slavery and "Indian removal." This earned him support from voters in southern and frontier states. The other three candidates were John Quincy Adams of Massachusetts, Henry Clay of Kentucky, and William Crawford of Georgia. U.S. presidents are elected through the Electoral College. The Founding Fathers worried that Americans were to spread out to learn enough about the candidates. Under the Electoral College, Americans cast their ballot for the popular vote, which chooses the electors for each state. The number of electoral votes each state equals the number of representatives and senators combined. The candidates must win an absolute majority of electoral votes to win the election. In 1824, Andrew Jackson won the popular vote, but he did not win it in each state. Jackson and Adams both won many electoral votes. Jackson won the most with 99. However, a candidate needs an absolute majority of electoral votes to win. In 1824, Jackson needed 131 to win. When there is not majority winner, the election goes to the House of Representatives. This has only happened twice in U.S. history. Even though he won the popular vote and many electoral votes, Andrew Jackson lost the presidency in 1824. John Quincy Adams was the Secretary of State currently. Henry Clay was the Speaker of the House of Representatives. Henry Clay, receiving the least, was left out. However, as a leader in the House of Representatives, he had influence over the other members. Clay openly hated Jackson and there were rumors that Clay made a deal with Adams in exchange for his support. The House election declared John Quincy Adams president. Soon, he chose Henry Clay to fill the seat he left vacant, Secretary of State. Jackson was shocked and enraged. Although there was no inquiry of possible wrongdoing, Jackson accused Adams and Clay of making a "corrupt bargain." John Quincy Adams was a disappointment as president. Many of his goals created divisions like federal funds for internal improvement. Some states thought that taking federal funds would force them to follow certain rules. They felt this reduced their rights as independent states. Jackson took advantage of issues like this one to gather more support. More Jackson supporters found their way to seats in Congress. He was as a man of the people and said Adams could never understand the common man's concerns. John Quincy Adams ran against Andrew Jackson in the 1828 election. Personal attacks grew even more vicious, but Andrew Jackson appealed to many. He believed government was for the common man. He believed in strict reading of the law and limited internal improvements. He also believed in states' rights. Andrew Jackson easily won the 1828 election, winning both the popular vote and most electoral votes. Historians note the sectional nature of the voting. Support for Jackson was concentrated in South while Adams' support was mostly in the North. Jackson was so popular because he brought changes to the government. He also wanted to make sure the government was responsible for its actions. Jackson pushed settlement into the frontier. He supported the Indian Removal act. He also defended the spread of slavery. Though his support was heavier in the South, he was determined to keep a unified nation. The rise and presidency of Old Hickory is memorable to Americans today.
