PLz help me! We r doing semester finals and i need to get this lesson finished in 2 hours!

Answer:

Ans = 42

Step-by-step explanation:

just substitute the variables with their respective value

x² + 2y ÷ w + 3z

= 5² + 2(8) ÷ 2 + 3(3)

= 25 + 16 ÷ 2 + 9 <bear in mind, have to do multiplication/division before addition/substraction>

= 25 + 8 + 9

= 42

Answer:

x = 1

Step-by-step explanation:

-8(1+4x)+7x=-25-8x (Given)

-8 + -32x + 7x = -25 - 8x (Distribute)\

-8 + -25x = -25 - 8x (Combine like terms)

-17x = -17 (Move variables(x) to the left and constants to the right)

x = 1 (Divide) (the answer is positive because when you divide a negative number by a negative number it turns positive)

Answer:

68%

Step-by-step explanation:

     Here, it asks for the percentage that attended, and percentage is a ratio expressed as a fraction of 100. First, we must start with the total number of students, not to be confused with the total number of students who attended. The total number of students in the class is 25, which we must multiply to get to a hundred.

     This depends on the number of course. For example, if the number were to be greater than 100, then you would divide, but never adding or subtracting, but in this case, we must stick with multiplying as 25 is less than 100. As you should know, 24 times 4 equals hundred, so you must multiply 17 by 4 too in order for it to be equal, which leaves you with 68/100 attending the part, meaning the percentage of students attending the dance is 68%.

Answer:

" all numbers less than -27 "

Step-by-step explanation:

The instructions for this problem most likely go like this:  "solve the following identity."  In other words, find an inequality for n.

Start by multiplying both sides of the given inequality by 3, to eliminate the fraction 1/3:

n < -27

The solution:  " all numbers less than -27 "

Step-by-step explanation:

Backpack 2 is 2x, 2y, so double each number:

(0,2) = (0, 4)

(8,2) = (16, 4)

(6,5) = (12, 10)

(2,5) = (4, 10)

(0,2) = (0,4)

Backpack 3 is x + 8, y - 2 so add 8 to x and subtract 2 from y:

(0,2) = (8, 0)

(8,2) = (16, 0)

(6,5) = (14, 3)

(2,5) = (10, 3)

(0,2) = (8, 0)

Backpack 4 is x, 2y, so keep the same x and multiply y * 2

(0,2) = (0, 4)

(8,2) = (8, 4)

(6,5) = (6, 10)

(2,5) = (2, 10)

(0,2) = (0,4)

Step-by-step explanation:

Answer:

Stem and Leaf Plot ⇒ Makes it easy to see the largest, smallest and most common data values.

Double Bar Graph ⇒ Compares two sets of data.

Bar Graph ⇒ Shows whether one type of data increases, decreases or neither when another type of data increases.

Scatter Plot ⇒ Shows the frequency of results and trends clearly.

Step-by-step explanation:

Stem and Leaf Plot makes a set of data easy to see and shows common data values together.

Double bar graph is the only graph that focuses solely on 2 sets of data.

Bar Graph description is a bit weird for this one to me but it's the last one (I did others first) and it is close enough.

Scatter plot is best at showing frequency and trends and to see the approximate increase/decrease of many data points.

Answer:

1. 4/3 and 2. 2?

Step-by-step explanation:

I have no clue tbh

EXPLAIN:    [tex]\frac{8}{6}= \frac{4.2}{3.2} =\frac{4}{3}[/tex]            [tex]\frac{4}{3}[/tex] ÷ [tex]\frac{2}{3}[/tex] = [tex]\frac{4}{3}.\frac{3}{2} =\frac{2.2}{3}.\frac{3}{2}=2[/tex]

ok done. Thank to me :>

Answer:

14. decrease

15. divide 59.95 by 40

16. increase

Answer:

3 hours

Step-by-step explanation:

2 hours equals 120 minutes add 15 minutes you get 135 minutes when you divide 135/3 you get 45 minutes per quarter so 45*4=180 minutes  180/60=3

Answer: The answer would be 950 international minutes. Only if assuming that this is in one month since the question doesn't give much detail.

Step-by-step explanation:

X would be used to represent the number of months.

25+0.10x=120

0.10x=95

950 international minutes used

Answer:

950

Step-by-step explanation:

An equation to model this scenario would be: y = 0.1x + 25

y would mean the amount of money paid depending on x, which is the number of minutes.

In this problem, we know the amount of money. So we know y is 120.

We can then put 120 into the equation to find x.

120 = 0.1x +25  

95 = 0.1x

x = 950

Therefore, x is 950.

Answer:201.06

Step-by-step explanation:

area of a circle = [tex]\pi[/tex][tex]r^{2}[/tex]

Radius of table = d/2 = 16/2 = 8

The area of the table = 8^2 x [tex]\pi[/tex] = 64[tex]\pi[/tex] = 201.06 (2.d.p)

Answer:

if there can be no more than 5 students, then anything less than 5 students will suffice. However we don’t want any left over ones cause we don’t want that one kid sitting alone during lunch so we can simply put 4 into each group.

Step-by-step explanation:

Hope this helped :DDD

Answer:

6 groups, 4 students in each one

Step-by-step explanation:

The factors of 24 include 6 and 4

That means that you can break 24 into those numbers

You are able to put the students up into groups of 6, with 4 students in each

However, you cannot place the students into groups of 4 (with 6 students in each) because no more than 5 students are allowed in each group
