Answer:

FGCE

Step-by-step explanation:

1. 3x - 9 = 30

add 9 to 30 ( 30 + 9 = 39) divide 39 by 3 (39 ÷ 3 = 13)

2. x/5 + 4 = 6

subtract 4 from 6 (6 - 4 = 2) multiply 2 by 5 (2 x 5 = 10)

3. x/2 + 6.5 = 8

subtract 6.5 from 8 (8 - 6.5 = 1.5) multiply 2 by 1.5 (2 x 1.5 = 3)

4. -2x + 2 = 18

subtract 2 from 18 (18 - 2 = 16) divide -2 from 16 (16 ÷ -2 = -8)

if 100 grams of meat costs 30 pesos,how much does 8 kilograms costs


Solution:
Answer:
Check:​

Answers

Solution:

First, we need to find out the amount for one kilogram. Since 100 grams = 30 pesos, and 1000 grams = 1 kilogram, we need to multiply it by 10.

30 x 10 = 300

Now we have the amount for 1 kilogram. Now in order to get the amount for 8 kilograms, we need to multiply it by 8.

300 x 8 = 2400 pesos

Answer:

The answer is 2,400 pesos.

Check:

30 x 10 = 300 So 300 pesos for a kilogram

300 x 8 = 2400 So 2400 pesos for 8 kilograms.

To solve this we are using the Pythagorean Theorem which is c^2=a^2+b^2.

In this case the c (hypotenuse) is x. Our equation will look like this:

x^2=15^2+8^2
x^2=225+64
x^2=289
We do the square root to undo ^2
x = 17

Bo' sister Anna is 3/4 his age minus 1 year. She is 11 years old.Write an equation to find Bo's age.

Answers

Answer: 16 years

Step-by-step explanation:

Let's Bo's age be represented by x.

Since Bo' sister Anna is 3/4 his age minus 1 year and she is 11 years old, this can be formed into an equation as:

(3/4 × x) - 1 = 11

3/4x - 1 = 11

3/4x = 11 + 1

3/4x = 12

Multiply both side by 4/3

x = 12 × 4/3

x = 16

Bo's age is 16 years

Answer:

x = 12 × 4/3

A Speedy River barge bound for New Orleans leaves Baton Rouge, Louisiana, at 9:00 A.M. And travels at a speed of 10 miles per hour. A Rail Transport freight train also bound for New Orleans leaves Baton Rouge at 1:30 P.M. The same day. The train travels at 25 miles per hour, and the river barge travels at 10 miles per hour. Both the barge and the train will travel 100 miles to reach New Orleans.

Answers

A rail transport freight train also bound for New Orleans leaves Baton Rouge at 1;30 PM on the same day. The train travels at 25 MPH and the river barge travels at 10 MPH. ... the barge leaves at 9:00 am so that would be at 9 hours past midnight. the train leaves at 1:30 pm so that would be at 13.5 hours past midnight.At 1.30 p.m. the barge has already traveled 4.5 X 10 = 45 miles.To catch up it will take the train 25-10 = 15 miles

Using the library and the Internet, find one research source about the topic. Your source should be at least five hundred words in length, or, if you select a print source, at least four to five pages.Choose one topic:a major Civil War battleCivil War munitions and uniformsthe Emancipation Proclamationthe Gettysburg AddressAfter you find your source, you should meet with your teacher to get it approved before moving on to the next step.Good readers rely on a set of skills to help them understand a text. You can use these strategies as you read the research source about the Civil War.If possible, print a version of the text that you can write on. It is helpful to highlight key points and make notes in the margins. This strategy is called annotating.When you find words or phrases that you do not know, do not skip over them. There is a series of steps you can take to understand the meaning of these words and phrases, so that you do not miss out on key ideas.Context clues: Look at the words before and after the unknown word or phrase. Using the surrounding text, or context, can you find any clues to the meaning of the unknown word?Using a dictionary: To find the specific meaning of a word, including helpful information like part of speech, word origin, and multiple meanings, you can use a dictionary. There are both print and online dictionaries available.Using an encyclopedia: Some words or phrases may have an important historical or contextual meaning behind them, especially in a social studies or history text. In this case, an encyclopedia is an excellent resource. For example, you would not want to simply use a dictionary to look up George Washington; in fact, an encyclopedia would provide you with a clearer meaning.After annotating the text, go back and read the text one more time. You might notice new details that you missed the first time.After you have finished reading the text a second time and have defined any unknown words, jot down some notes about the key points or ideas. It can be helpful to write a quick summary of the source in order to prepare you for your next step: writing a report.DirectionsChoose one Civil War topic from the list below.
