Answer:

oof that is messed up

Answer:

y=4x−11

Step 1: Flip the equation.

4x−11=y

Step 2: Add 11 to both sides.

4x−11+11=y+11

4x=y+11

Step 3: Divide both sides by 4.

[tex]\frac{4x}{4}[/tex]  =  [tex]\frac{y+11}{4}[/tex]

x= [tex]\frac{1}{4} y[/tex] + [tex]\frac{11}{4}[/tex]

y=-8x + 13

Step 1: Flip the equation.

−8x+13=y

Step 2: Add -13 to both sides.

−8x+13+−13=y+−13

−8x=y−13

Step 3: Divide both sides by -8.

[tex]\frac{-8x}{8}[/tex]  =  [tex]\frac{y- 13}{-8}[/tex]

x= [tex]\frac{-1}{8}y[/tex]  +  [tex]\frac{13}{8}[/tex]

Answer:

Mean:29.25

Median:25

Mode:25

Outlier:69

Range:53

Step-by-step explanation:

mean: 18+69+22+27+32+25+16+25/8=29.25

median: put in order: 16+18+22+25+25+27+32+69

middle is 25+25/2 which is 25.

median:25.

Mode = 25.

Outlier = 69.

Range is 69-16=53

Hope this helps :) pass your test :)

Answer:

mean = 29.25

median = 25

mode = 25

outlier = 69

range = 53

Step-by-step explanation:

Mean: add all values and divide by number of values   234 ÷ 8

Median: middle value if there are an odd number of data values, or the average of the two middle values if there are an even number of data values    

Mode:  data item seen most often

Outlier = data value that is extreme

Range = Highest value minus lowest value

Answer:

178.5mcg

Step-by-step explanation:

If you need 5000 per 125mcg, we can express it as;

5000 = 125mcg

To get the amount of mcg needed for 7140, we will say;

7140 = x mcg

Divide both expression

5000/7140 = 125/x

Cross multiply

5000x x= 7140 * 125

5000x = 892,500

x = 892,500/5000

x = 178.5

Hence the amount og mcg needed is 178.5mcg

Answer:

Zoey needs 51 more beads to make 5 bangles.

Step-by-step explanation:

Total number of beads Zoey currently has = 99 beads

Beads need to make one bangel = 30 beads

so

Beads need to make 5 bangles = 30 × 5 = 150 beads

Since she has already 99 beads.

So, all we need s to subtract 99 beads from 150 beads.

Therefore,

The number of beads Zoey needs = 150 - 99

                                                          = 51 beads

Thus, Zoey needs 51 more beads to make 5 bangles.

2= 15x-35+20y

3= 4(4x-3)

4= 6(6x-1)

5= 24x-109

6= 7.5x+20y

Answer:

12.15 *10^4

=1.215 *10^5

it must be like that so as to express it in standard form

The sum of (5.2 × 10⁴) and (6.95 × 10⁴) in scientific notation will be 12.15 × 10⁴.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The numbers in the scientific notation will be given as,

(5.2 × 10⁴) and (6.95 × 10⁴)

Then the sum of the numbers will be

⇒ (5.2 × 10⁴) + (6.95 × 10⁴)

⇒ (5.2 + 6.95) × 10⁴

⇒ 12.15 × 10⁴

The sum of (5.2 × 10⁴) and (6.95 × 10⁴) in scientific notation will be 12.15 × 10⁴.

Answer:

639 students attend the highschool

Step-by-step explanation:

Find one-ninth of the students

Since 142 students is two-ninths of students, we would divide

1) 142/2=71

71 students is only one ninth of the students, we need to find 9/9 of students

2) 71*9 = 639

639 students attend school

There is a total of 639 students in the school.

If we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.

It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.

Let's say the number of students in the school is x

Then,

Since 2/9 of it are in the school band

So,

(2/9) x = 142

x = 639

Hence "There is a total of 639 students in the school".

48.3

Step-by-step explanation:

bc =9)4

b=9

c=4       sooo 9x4=36 anddd 36+12.3=48.3. :P

Answer:

48.3 is the answer.

Step-by-step explanation:

*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^

Essentially, you are just multiplying and adding.

When it says b = 9 and c = 4, that is representing the variables. Just think of the variables as x and y (which are normally used as variables).

So, in the equation, we see that b and c are together, meaning that they need to be multiplied. When we plug in the values for those variables, we see that the equation now says:

9 * 4 + 12.3 =

Now, we just multiply 9 by 4, and add 12.3.

36 + 12.3 =

48.3

This means that the equation bc + 12.3 is equal to 48.3.
