whoops i was confused a bit with the answers this is the same as the last one

Step-by-step explanation:

1.) 5x-4y=20

y=5/4x-5

5x/4-5=0

x=4

2.) 3x+3y=15

y=-x+5

x+5=0

-x=-5

=x=5

3.) y=3/4x-2

3/4x-2=0

x=0

3x4x/4 -2 x4x-0x4x

3-2x4x=0x4x

3-8x=0

8x=-3

=x=3/8

4.) y=3/2x+3

3/2x+3=0

x=0x

3x2x/2+3x2x=0x2x

3+3x2x=0x2x

3+6x=0

6x=-3

x=_3/6

=x=-1/2

Answer:

Artaud's age is 16.

Step-by-step explanation:

Answer:

The answer is B, 38.75

Step-by-step explanation:

The mean, you add up all the numbers and divided it by how much numbers are there.

1) 20 + 22 + 25 + 31 + 33 + 34 + 41 + 41 + 45 + 50 + 56 + 67 = 465

2) Count. How many numbers are there? There are 12 numbers.

3) 465/12 is 38.75

The answer is B, 38.75

Hope this helps :)

Answer:

D.

Step-by-step explanation:

According to the dot plot,

3 students spend 0.5 minutes brushing their teeth.

2 students spend 1.5 minutes brushing their teeth.

1 student spends 2.5 minutes brushing their teeth.

2 students spend 3.5 minutes brushing their teeth.

1 students spend 4 minutes brushing their teeth.

So, the number set will be: {0.5, 0.5, 0.5, 1.5, 1.5, 2.5, 3.5, 3.5, 4}

Median: The middle number in a set that is ordered from least to greatest.

In this example, the median is 1.5

Mean: The sum of all values divided by the number of values.

In this set there are 9 values so we’ll divide the sum by 9

In this example, the mean would be:

(0.5 + 0.5 + 0.5 + 1.5 + 1.5 + 2.5 + 3.5 + 3.5 + 4) ÷ 9

18 ÷ 9 = 2

If we compare the mean to the median we can see that the mean is greater because 2 > 1.5

Answer:

4

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.

Answer:

a = (4 - 9b)/2

w = (t - 3)/7

Step-by-step explanation:

2a + 9b = 4

2a= 4 - 9b

a = (4 - 9b)/2

t = 7w + 3

7w = t - 3

w = (t - 3)/7

Answer: I should measure first but I can not because it is an image but I leave you the explanation of how to do

Step-by-step explanation: Two angles are complementary if the sum of their degrees is equal to 90º (ninety degrees). For example: a 30º angle and a 60º angle are two complementary angles. Since 90º is the measure of a right angle, another way of saying that two angles are complementary is that together they form a right angle

Answer:

-3n-4n = 25 + 17

-7n = 42

n= -6

the main thing for here is to combine the like terms and to solve for n which is done by putting all the numbers with variables on one side and the non variables on the other and divide each side by the number that has the variable. Remember that when you bring numbers on the other side, you change its sign, for example if you have 5 on one side and you bring to the other side of the equal sign it becomes -5.

-15 + 15d -7.5d =7.5

15d - 7.5d = 7.5 + 15

7.5d = 22.5

d = 3

for the part where theres 7.5(2d-1)

you multiply each number inside the bracket by 7.5, its called distributivity of multiplication

hope that answers your question

hope you understand what i wrote lol

good luck:)

Answer:

Question 1

Original Equation:

-3n-4n-17=25

Add 17 to both sides (cancels out the -17)

-3n-4n=42

Combine -3n and -4n.

-7n=42

Divide by -7

n = -6

Question 2

Original Equation:

-15+7.5(2d-1)=7.5

Distribute:

-15+15d-7.5=7.5

Add 7.5 to both sides:

-15+15d=15

Add 15 to both sides:

15d=30

Divide by 15:

d = 2

Answer:

Strawberry= 3
Watermelon=3
Coconut=9
Orange=5

Step-by-step explanation:

Quite easy, you can use substitution

First look at the simplest row that can be solved by itself

row 2:

2strawberries +4 = 10

2 strawberries= 6

1 strawberry = 3

Row 3: Strawberry(3)+ orange=8

1 orange= 5

Rpw 4: 14= 1coconut +orange(5)

1 coconut= 9

Row 1: Coconut(9)+ watermelon+ coconut(9)= 21

2 coconut(18)= 21

1 watermelon = 3

Answer:

6,-24 is our NEW IMAGE.

Step-by-step explanation:

OUR PRE-IMAGE is currently in QUADRANT 1

moving 90 degrees clockwise moves it into the QUADRANT 4.

In a 90 DEGREE rotation, we have to SWITCH THE x, and Y.

6,24 is our new values after switching the x and y.

Now we can use the quadrant rules,
