I need some help, pls

Step-by-step explanation:

Your expression is technically correct. However, the root notation is by default referring to the square root of the number, and we often neglect it for convenience.

Also for the sake of convenience, we also write x mean we mean x^1.

2)

80 +67 +97+ 98 +85 +72 = 499

499/6=83.1666666667

Average: 83.1666666667

3)

a) 97 93 92 90 90 90 86 =90

median of Edgars grades for his midterm is 90

99 93 93 89 88 88 86

median of Edgars grades for his trimester is 89

7)

(z+9+18)= z+27 (remember don't mix the numbers if they are attached to the x)

(z+18+9)= z+27 (because adding is both ways the same)

a) a + b =b + a

Geometry

1.

a) 6x^2

b)The surface area of a cube = 6a^2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, x is just the length of one side of a cube

c) The unit would be sq(squared) feet

Answer:

26 minutes

Step-by-step explanation:

Since the mean is the average of all the number, we need to reach a total of 315 minutes for the entire week.

[tex]35+40+37+42+45+50=\\75+40+37+42+45+50=\\115+37+42+45+50=\\152+42+45+50=\\194+45+50=\\239+50=\\289[/tex]

Step-by-step explanation:

Ok...so yes the greater number is 7 but 7 is also the number farther from zero because when the positives and negatives are ignored, it takes 7 unit spaces to get to 7 whereas it only take 3.25 to get to the negative, making 7 farther from 0 than -3.25.

Step-by-step explanation:

we turned the number into a fraction

Step-by-step explanation:

Perimeter = 12 + x + 6 + 2x + 5

Perimeter = 3x + 23.

Area = ½ × b × h

Area = ½ × 12 × (x + 6)

Area = 6(x + 6)

Area = 6x + 36

Step-by-step explanation:

To add integers on the number line, you move forward, and you face right (the positive direction) when you add a positive number. As with positive numbers, to add negative integers on the number line, you move forward, but you face left (the negative direction) when you add a negative number.

Answer: any number or variable adding or subtracting when moved to the other side of the equal sign changes sign. Also you can change all the signs in both sides of the equation. so -a = 6 is the same as a = -6 or -6 = a.

Answer:

x = 15, 72 degrees

Step-by-step explanation:

4x + 12 + 108 = 180

4x + 120 = 180

4x (+ 120 - 120) = 180 - 120

4x = 60

4x/4 = 60/4

x = 15

4x + 12

4(15) + 12

60 + 12

72 degrees

Answer:

q = 3.5

Step-by-step explanation:

Start by distributing the 5

-15 = 15q - 50 - 5q

Combine like terms

-15 = 10q - 50

Add 50 to both sides

35 = 10q

Divide by 10 to isolate q

35/10 = q

q = 3.5

Answer:

q=3.5 or 4

Step-by-step explanation:

-15=5(3q-10)-5q

-5=15q-50-5q

-15+50=15q-5q

35=10q

Divide both sides by 10.

35÷10=10q÷10

3.5=q

Therefore,q= 3.5

Round up=4

the person could be very lazy and just dot down whatever they feel like or could take their time with the assignment an get a fairly god grade. on a four choice yes the typical score would be 70 and for a two choice test It would be around 50 depending on the amount of questions and whether the "Jimmy" gives a d4mn :)

Try this solution, note a) the suggested way is not the only one, b) the suggested solution is for segments AC:CB=2:1 only.

1) if the point A is (-7;-9), the point B is (5;6) and C is required point, then

2) the coordinate 'x' of the point C is:

[tex]X_C=X_B-\frac{X_B-X_A}{2+1}=5-4=1;[/tex]

3) the coordinate 'y' of the point C is:

Answer:

Its A

Step-by-step explanation:

Answer: 8.5 miles

Step-by-step explanation:

Given information

Base fee = $3.00

Fee per mile = $2.00

Distance = x

Total money spend = $20

Set equation

3 + 2x = 20

Subtract 3 on both sides

3 + 2x - 3 = 20 - 3

2x = 17

Divide 2 on both sides

2x / 2 = 17 / 2

[tex]\boxed{x=8.5}[/tex]

Step-by-step explanation:

The order must always be the same.

Answer:

2 21/40

Step-by-step explanation:

First, you take the fractions in the parenthesis and make the denominators alike by finding the least common multiple. Once you've done that you can add them together and then add the outer fraction. When adding the outer fraction, you need to make it into an improper fraction. I hope this helped! :)

The given pattern is an illustration of a linear equation. The students' equations are:

Given that:

[tex]n \to[/tex] number of tiles

[tex]s\to[/tex] step number

See attachment for the pattern, that is being analyzed by the students.

Dan

For each step, the number of tower is the same as the step number.

This means that:

[tex]n \to s[/tex]

2 arms contain one less block means: 2 x (s - 1) blocks for both arms.

So, Dan's equation is::

[tex]n = s + 2 \times (s - 1)[/tex]

[tex]n = s + 2(s - 1)[/tex]

Sally

First, we calculate the slope (m) of the table

[tex]m = \frac{n_2 - n_1}{s_2 - s_1}[/tex]

So, we have:

[tex]m = \frac{4-1}{2-1}[/tex]

[tex]m = \frac{3}{1}[/tex]

[tex]m =3[/tex]

The equation is then calculated using:

[tex]n = m(s - s_1) + n_1[/tex]

This gives:

[tex]n = 3(s - 1) + 1[/tex]

Open bracket

[tex]n = 3s - 3 +1[/tex]

[tex]n = 3s - 2[/tex]

Hence;

Dan's equation is: [tex]n = s + 2(s - 1)[/tex]

Sally's equation is: [tex]n = 3s - 2[/tex]
