Answer:

a = 6

Step-by-step explanation:

120 = 3 + 3(7a - 3)   (by PEDMAS, expand parentheses first by distributive property)

120 = 3 + 7a(3) - 3(3)

120 = 3 + 21a - 9

120 = 21a - 6    (add 6 to both sides and rearrange)

21a = 120 + 6

21a = 126   (divide both sides by 21)

a = 126/21

a = 6

Step-by-step explanation:

120-(3+3*(7*a-3))=0

The mode is the most common number in the data set. If there are two numbers that appear frequently (in this case 69 and 73) then this data set has two modes.

The median is the middle of the set of numbers (line them up from top to bottom).

In this case it should look something like:

68 68 69 69 69 69 70 70 71 72 72 73 73 73 73 75 78

If the whole list of numbers are even, then pick the two middle numbers and find their average. If it is odd, just choose the middle most number.

Mean is the average of all numbers. If you have 5 numbers, add them all up and divide by 5. If you have 10 numbers, add them all up and divide by 10.

Two straight lines have equations y = p x + 4 y = p x + 4 and p y = q x − 7 p y = q x − 7 , where p p and q q are constants. The two lines meet at the point ( 3 , 1 ) ( 3 , 1 ) . What is the value of q q ?

Answers

Answer:

q = [tex]\frac{8}{3}[/tex]

Step-by-step explanation:

The point of intersection (3, 1 ) is the solution to both equations

Using

y = qx - 7 and substituting x = 3, y = 1

1 = 3q - 7 ( add 7 to both sides )

8 = 3q ( divide both sides by 3 )

[tex]\frac{8}{3}[/tex] = q

Step-by-step explanation:

Solve 8x – 5 = 23 + 4x.

Answers

Answer: X equals 7

Step-by-step explanation:

Answer:

7

Step-by-step explanation:

First you want to simplify the equation

8x + (-5) = 23 + 4x

-5 + 8x = 23 + 4x

Then solve for x, but before we do that we !!!must!!! move all terms that have x  to the left. Everything else would go to the right.

So we add -4x to both sides ..

-5+ 8x + (-4x) = 23 + 4x + (-4x)

-5 + 4x = 23 + 4x + (-4x)

-5 + 4x = 23 +0

-5 + 4x  = 23

Then add 5 to both sides of the equation:

-5 + 5 + 4x = 23 + 5

0 + 4x = 23 + 5

4x = 23 + 5

4x = 28

Then divide each side by 4:

x = 7

And there you have it. The answer is 7. Hope this helps! :)

Solve the system by substitution.
y=-4x
y=x-5

Answers

You would plug in y into the other equation.
-4x = x-5
Put x variables on one side
-4x - x = -5
-5x = -5
x=1
Then plug in 1 for x in any equation
y = 1 - 5
y = -4
So the answers are x=1 and y=-4

Shelley's kitten weights 2 1/3 times as much as she did last year. She now weighs 21 ounces. What did the kitten weight a year ago?

Answers

Answer:

weight of the kitten last year = 9 ounces

Step-by-step explanation:

Let

x = weight of the kitten last year

Weight of the kitten this year = 2 1/3 * x = 21

7/3*x = 21

7/3x = 21

x = 21 ÷ 7/3

x = 21 × 3/7

= 63/7

x = 9 ounces

weight of the kitten last year = 9 ounces

Cite text evidence to support your answer.Text: From Chapter Twenty-Two: Learning How to Settle in Flint Id been having such a good time being Little Stew and trying to fill in all the missing words from the Readers Digest that time had completely run off and forgot all about me! But, Mother, Miss Stew needs me to You arent suggesting you stay here and help Stew instead of going to school, are you? When she said it like that, it did seem silly. ***On the outside, schools in Flint seemed a lot like schools in Gary, but they werent. Instead of having one teacher all day, in Flint we went from classroom to classroom and teacher to teacher for each subject. The teachers were different too. First, all of them were white, and second, they werent anywhere as nice as the teachers in Gary. But one of Mrs. Needhams lessons stuck: I was learning how to toughen up. I got my usual As on the tests in mathematics, geography, civics and history. After my first mathematics test, when class was dismissed, Mrs. Scott called me to her desk. Deza, have you always done so well in math? Youre the only student who got a perfect score. I sounded very humble, but the truths the truth. Yes, maam. Mathematics is one of my favorite subjects. It was great to be back in school! Could I ask you a favor? Maybe she wanted me to help some of my classmates. Even though they were white, some of them were the spittin image of Dolly Peaches and Benny Cobb. She slid a paper toward me. It had five unsolved story problems on it. Could you sit right there, right now, and solve these for me? Maybe Mrs. Scott was seeing if I was ready for harder work. I finished in no time. She looked them over. Hmm, perfect again, but next time you must make sure to show all your work. Youre dismissed. I was surprised that was all she said. In English class I really showed how much Id toughened up. Flint teachers dont have the imaginations that Gary teachers do, so instead of giving grades back so everyone knows what you got, they walk around the class and hand your test or paper back to you. Upside down. Mr. Smith was passing out our first essay. Id followed all of Mrs. Needhams advice. Id written it at the Flint Public Library and was very careful not to use the dictionary or the thesaurus too much. And I didnt digress at all. I made sure my posture was good, crossed my ankles and folded my hands on the desk when he got close to me. He handed me my paper and smiled. Very good job. My heart flew! Thank you, sir. I turned my paper over. Hed written, Good for you! and put a giant C+ with three exclamation points. I turned the paper back over. Maybe I saw it wrong. I looked again but it was the same. One sign that I had toughened up was that instead of crying I thought of a little joke that Jimmie said he did whenever he didnt like his grade. I turn the paper over, then, the same way people bang on a machine it if aint acting right, I smack my hand on the paper. Maybe if I bang it hard enough my grade will jump up a mark! It was nonsense, but I slapped my hand on Mr. Smiths essay. I turned the paper back over and smiled. Id have to tell Jimmie that it still wasnt working. Mrs. Needham wouldve been proud. Instead of bawling, I looked at Mr. Smiths back and said to myself, OK, buster, Im going to make sure my next essay is the best thing Ive ever written. You wont have any choice but to give me my A plus. When me and Loretta were walking back to camp I asked, What grade did you get on your essay? I dont know, the same old D. Whatd you get? C plus. She stopped walking. Uh-oh, no, you didnt! I showed her my grade. Ooh, girl, you must be real smart. For getting a C plus? All these teachers up here at Whittiers prejudice. Katherine Williams was the smartest colored girl in the school and all she use to get was a C. You must be a genius to get a C plus! She laughed.
