3(у - 3) - 2(у 4) = 4​

Answers

Answer 1

Answer:

y = 5

Step-by-step explanation:

3(у - 3) - 2(у -4) = 4​

Distribute

3y -9 -2y +8 =4

Combine like terms

y -1 =4

Add 1 to each side

y-1+1 = 4+1

y = 5

Answer 2

Answer:

y = 5

Step-by-step explanation:

So I'm gonna assume this is 3(y-3) - 2(y-4) = 4

Use the distributive property

3y - 9 - 2y + 8 = 4

y - 1 = 4

y = 5

LONGEST SIDE:__________

Answers

Answer: 29 centimeters long

Step-by-step explanation: What you want to do in this kind of situation is to combine all like terms. After, you would get 6x + 24 = 150. What you would do here is to get 6x by itself by subtracting 24 on both sides. Now 6x = 126, to isolate the variable you divide 6 on both sides to get x = 21. However, the questions is asking for the longest side and you know that x + 8 will be the greatest out of all. So, x = 21 + 8 equals 29 centimeters. I hope this helps, please give me a brainlest! :)

We know that the polygon is a six side shape because there is 6 measurements

Perimeter: all sides added

First add the given numbers
6+4+5+8+1=24

Then subtract that number from answer
150cm-24cm=126cm

Divide that by the amount of numbers
126/6=21

That means ’x’ is 21
Now you have;
21(x)
27(x+6)
25(x+4)
26(x+5)
29(x+8)
22(x+1)

Make sure they all add to 150
21+27+25+26+29+22=150cm

To find the longest side you look and the largest number which is 29

LONGEST SIDE= x+8

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The descending numbers are calculated as:-

2.4√(3π) → 7.3679

(221/30)  → 7.3666

7.36 bar  → 7.3636

(7[1/3]).    → 7.3333

Q1. If ∛5x+10=5, Find x

Answers

Answer: x=-25

Step-by-step explanation:

Concept to know:

When given a number that is cubic root, in order to solve the equation/function, you need to cube numbers on both sides.

Solve:

Given

∛5x+10=5

Subtract 10 on both sides

∛5x+10-10=5-10

∛5x=-5

Cube numbers on both sides

5x=-125

x=-25

Answer:

x = -25

Step-by-step explanation:

If ∛5x+10=5, Find x

∛5x = 5 - 10

∛5x = -5

take both sides of equation to the power of 3

5x = -125

x = -125/5

x = -25

Answers

Answer:

The temperature difference is equal to 27-(-4)=31.

Step-by-step explanation:

Answer:

31° .

Step-by-step explanation:

we need to calculate the temperature difference between 2 pm and 2 am we can get the difference by subtracting the temperature at 2 am from the temperature at 2 pm

the temperature at 2 pm is 27°  

the temperature at 2 am is -4°

the temperature difference between 2 pm and 2 am is:

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

PLEASE HELP ASAP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Part A: To calculate the measures of center, we can find the median and the mean for each school.

For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.

To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.

For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.

To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):

18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.

Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.

The measures of center for Seaside School are: median = 15, mean ≈ 15.9.

Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.

For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.

To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.

For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.

To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.

Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.

The measures of variability for Seaside School are: range = 15, IQR = 6.

Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.

Answers

Answer:

Step-by-step explanation:

the number should be 212.02568593112

Answer:

3426/3200 = 1.070625. So, 277/___ = 1.070625

We have to find the equivalent fraction

Step-by-step explanation

We can turn 1.070625 into a  fraction 1713/1600 .

This is so we can cross multiply

Answer: 212.02568593111

You can cross multiply 3426 x 212.02568593111 = 726400

Then cross multiply 3200 by 227 = 726400

Since these are equal, the answer is 212.02568593111.

Jason spent $30 at a baseball game. He spent $10 on the ticket, $12 on nachos, and he bought a soda. He does not remember how much the soda was. Which of the following is an equation that can help him solve for his missing soda price?

A 10 + 12 + j = 30

B 30 = j -10 -12

C 30 + 10 + 12= j

D 12+ j -10 = 30

Answers

Answer: A

Step-by-step explanation: You are saying that when he bought all of these things he spent $30. So all of your items have to add up to 30.  Answer A is saying Ticket+Nachos+Soda=total.

The answer is A) 10 + 12 + j = 30

When you come across a problem like this, try sounding it out in your head. Even though the question is asking for an equation that would help find the missing soda price, j won’t be behind the equal sign because $30 is how much Jason spent in total. The ticket price, plus the nachos, plus the soda price equal 30 dollars, so A) would be the best option.

In order to solve the equation, since we’re dealing with money here and trying to reach $30, adding up the price of the ticket and the nachos makes the most sense:

10+12+j=30
22+j=30

$22 plus the soda price is $30, so in order to find j, find the difference between 22 and 30 ( basically 30-22) which is 8. the soda price was $8

To check your work, plug in $8 in place of j like this:

10+12+8

If the equation equals 30 (which it does), then the j value you came up with is right.
Good luck on the rest of your math stuff, hope this helped
