Answer:

x<2/3b+-8/3

Step-by-step explanation:

Let's solve for x.

−3x+2b>8

Step 1: Add -2b to both sides.

2b−3x+−2b>8+−2b

−3x>−2b+8

Step 2: Divide both sides by -3.

-3x/-3>-2b+8/-3

x<2/3b+-8/3

Answer is : x<2/3b+-8/3

did she use?​

Answers

Answer:

4. His classmate's daily allowance is of P100.

5. She used 25% of the sheets of art paper.

Step-by-step explanation:

4. Manuel, a son of a school janitor, does not ask for more. He has a daily

allowance of P10 a day which is 20% of his classmate's daily allowance. How much is his classmate's daily allowance?

An allowance of P10 a day is 20% of his classmate's allowance, that is, 20% of x. So

[tex]0.2x = 20[/tex]

[tex]x = \frac{20}{0.2}[/tex]

[tex]x = 100[/tex]

His classmate's daily allowance is of P100.

5. Carla, a grade six pupil , has 24 sheets of art paper for his project in Math. If 6 sheets of art paper were used by Carla, what percent of the sheets of art paper did she use?​

She used 6 sheets, of the 24. So

[tex]P = \frac{6*100}{24} = \frac{100}{4} = 25[/tex]

She used 25% of the sheets of art paper.

Of the shirts produced by a company, 6.5% have loose threads, 9.5% have crooked stitching, and 3% have loose threads and crooked stitching. Find the probability that a randomly selected shirt has loose threads or has crooked stitching.

Answers

Answer:

[tex]P(L\ or\ C) = 0.13[/tex]

Step-by-step explanation:

Given

Represent loose threads with L, Crooked stitching with C.

So, we have:

[tex]P(L) = 6.5\%[/tex]

[tex]P(C) = 9.5\%[/tex]

[tex]P(L\ and\ C) = 3\%[/tex]

Required

Calculate P(L or C)

In probability:

[tex]P(A\ or\ B) = P(A) + P(B) - P(A\ and\ B)[/tex]

In this case:

[tex]P(L\ or\ C) = P(L) + P(C) - P(L\ and\ C)[/tex]

Substitute values for P(L), P(C) and P(L and C)

[tex]P(L\ or\ C) = 6.5\% + 9.5\% - 3\%[/tex]

[tex]P(L\ or\ C) = 13\%[/tex]

Convert to decimal

[tex]P(L\ or\ C) = 0.13[/tex]

Hence:

The required probability is 0.13

Step-by-step explanation:


Suppose that the functions r and s are defined for all real numbers x as follows.

Answers

Answer:

a)  ( r+ s) (x)  = 3 x + 9

b)   ( r . s ) (x) =  2 x² + 13 x +20

c) ( r- s) (x)  = -1 -x

Step-by-step explanation:

Step(i):-

Given that r(x) = x +4 and s(x) =  2x + 5

a)   ( r+ s) (x)  = r(x) + s(x)

                    = x +4 + 2x +5

                   = 3 x + 9

    ( r+ s) (x)  = 3 x + 9

b)

    ( r . s ) (x)  = r(x) . s(x)

                    = (x+4) . ( 2x +5)

                   = x ( 2x +5) + 4( 2x +5)

                  = 2 x² + 5 x + 8 x +20

                 = 2 x² + 13 x +20

( r . s ) (x) =  2 x² + 13 x +20

c)

 ( r- s) (x)  = r(x) - s(x)

               =  (x+4 - ( 2x +5)

              = x +4 - 2x -5

            = -x -1

( r- s) (x)  = -1 -x

Solve x and y 3x-4y=18,9x-2y=12

Answers

Answer:

3x-4y=18

1xy=18

xy=18 ans

Answer:

X=2/5

Y=-21/5

Step-by-step explanation:

solve your system by substitution.

3x−4y=18;9x−2y=12

Step: Solve3x−4y=18for x:

3x−4y=18

3x−4y+4y=18+4y(Add 4y to both sides)

3x=4y+18

3x/3=4y+18/3

(Divide both sides by 3)

x=4/3y+6

Step: Substitute 4/3y+6 for x in 9x −2y=12:

9(4/3y+6)−2y=12

10y+54=12(Simplify both sides of the equation)

10y+54+−54=12+−54(Add -54 to both sides)

10y=−42

10y/10=-42/10 .   (Divide both sides by 10)

y=-21/5

Step: Substitute

21/5 fory in x= 4/3y+6

x= 4/3y (-21/5) +6

  X=2/5 (Simplify both sides of the equation)

           Answer:

          X=2/5

          Y=-21/5

Determine whether or not the following graph represents two quantities that are proportional to each other. Explain your reasoning.

Answers

Answer:

The quantities are not proportional.

Step-by-step explanation:

The values, x and y, do not begin or pass through the origin, (0,0). This means they are not proportional.

The graph represents two quantities are not proportional to each other.

What is Proportional?

A relationship is proportional if each pair of data values are related in the same way, by multiplying by a factor. You can recognize a proportional relationship by looking at data, an equation, or a graph.

Given:

As, A relationship is proportionate if its graph is a line or ray that passes through the origin.

and, It is not proportionate if the line or ray does not go through the origin. Additionally, if anything is not linear, it is not proportional.

Here the graph also does not pass through the origin.

Hence, the graph is not proportional.

Angle Relationships

Answers

Answer:

In Geometry, there are five fundamental angle pair relationships:

Complementary Angles.

Supplementary Angles.

Adjacent Angles.

Linear Pair.

Vertical Angles.

The measure of the angle u and angle t will be 29 degrees.

What is an angle?

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

The angle u is congruent to angle t.

From the diagram, angle t, angle u, and angle 122 are supplementary angles. Then the equation is given as,

∠t + ∠u + 122° = 180°

∠t + ∠t  = 58°

2∠t = 58°

∠t = 29°

The measure of the angle u and angle t will be 29 degrees.

The guidance office at a high school surveyed their 12th grade students to know in which of four states they would prefer to live in after highschool. The results are summarized in the tso way frequency table below.

Which two-way table accurately represents the relative frequency for the whole table in this situation?

Answers

Hence, the two way frequency table is:

                  Action                 Drama                Comedy         total

Highschool  26/128=0.20          14/128=0.11           22/128=0.17     0.48      

College      20/128=0.16            28/128=0.22        18/128=0.14      0.52

total                   0.36                        0.33                     0.31                   1

Step-by-step explanation:

" When a two-way table displays percentages or ratios (called relative frequencies), instead of just frequency counts, the table is referred to as a two-way relative frequency table " .

We are given a table or data  as:

                         Action              Drama                     Comedy     Total

Highschool        26                     14                            22                 62

College              20                     28                            18                 68

------------------------------------------------------------------------------------------------------------

Total                            46                      42                           40               128

The total number of students in all the categories and classes are: 128

Hence the two way frequency table is constructed by dividing all the frequencies by the total number of students i.e. 128.

                               Action                 Drama                Comedy         total

High school      26/128=0.20          14/128=0.11           22/128=0.17     0.48      

College           20/128=0.16            28/128=0.22        18/128=0.14      0.52
