Find the value of X, I need help solving this

Answer:

123.8

Step-by-step explanation:

nearest tenth is 7 and the sixes aftr it are over half of a full decimal, so they round to 123.8

Answer:

x = 59/4

Step-by-step explanation:

4x + 9 = 68

Subtract 9 from both sides.

4x + 9 - 9 = 68 - 9

4x = 59

Divide both sides by 4.

4x/4 = 59/4

x = 59/4

Answer:

X=0.75

Step-by-step explanation:

Step 1:

68-9=59

Step 2:

59 divided by 4= 14.75

Step 3:

0.75=3/4

14 3/4=14.75

Solution:

X=0.75

Another way is 59/4=14.75

Answer:

-3x+1y=-1

or

3x-1y=1

or

by multiplying with 1/3 the first equation we get

-1x+1/3y=-1/3

or from second equation

1x-1/3y=1/3

Step-by-step explanation:

y-y1=m(x-x1)

y1=-7

x1=-2

m=3

so

y-(-7)=3(x-(-2))

y+7=3(x+2)

y+7=3x+6

-3x+y=6-7

-3x+ 1y= -1

Answer:

[tex]\huge{ \boxed{ \sf{No}}}[/tex]

✑ Question :

No , it's not a function.

✎ Reason :

This is not a function because one element 11 of set A is associated to elements 9 and 5 of set B.

♨ Explore about function :

↪ Function is a special type of relation. It is the refinement of relation. In a relation from A to B , every element of set A should have only one ( distinct ) image in B to be a function. In other words , if no two different ordered pairs have the same first component , then it is a function.

Hope I helped!

Have a wonderful day ! ツ

Answer:

the lines are NOT perpendicular because their slopes aren't negative reciprocals

Answer:

31.241

Step-by-step explanation:

x = 6t + 5,   y = 7 − 5t            −1 ≤ t ≤ 3

dx/dt = 6

dy/dt = -5

The arc length of the curve can be calculated below as

L = ∫[tex]\sqrt{(\frac{dx}{dt} )^2 + (\frac{dy}{dt})^2 dt }[/tex]

 = [tex]\int\limits^3_ {-1} \, \sqrt{36 + 25 dt}[/tex]

 = [tex]\sqrt{61} \int\limits^3_ {-1} \, dt[/tex]

 = [tex]\sqrt{61} [3-(-1)][/tex]

= 4[tex]\sqrt{61}[/tex]  = 31.241

Answer:

336 × 0.4 = 134.4

Step-by-step explanation:

used a calculator

First play = 30 yards gained

Second play = 40 yards lost

Third play = 10 yards gained

Total yards Jason has = +30 -40 +10

= +40 -40

= 0

Answer: 0

Step-by-step explanation:

30 - 40 + 10

30 - 40 = -10

-10 + 10 = 0

0 is your final answer

Answer:

Check below for step-by-step guide.

Step-by-step explanation:

a) Recall the formula for area is length times width. You are given both of those values. Width= (5x+2) and length = (4x-1). All you have to do is multiply them. You will get a quadratic!

b) This is just basically a lot of plugging in to the equation: Volume= length x width x height. So let's look at what we have!

It says our volume is 20x^3 + 63x^2+ 7x-6

It says our width is : (5x+2)

It says out length is (4x-1).

So the volume = l x w x h , we just plug in those numbers I listed above :

20x^3 + 63x^2+ 7x-6= (4x-1) (5x+2) (height)

Now remember you already multiplied length times width in problem (a). You can use that expanded quadratic on the right side. Then subtract values and isolate height!

You asked for an explanation of what to do step by step, so if you actually need help solving it, comment please! :)

Answer:

8persons/group

Step-by-step explanation:

Give parameters:

Number fourth graders = 24

Number of groups  = 3 groups

Unknown:

Number of students in each group = ?

Solution:

Solving this problem involves finding the number of persons per group.

 Number of persons per group = [tex]\frac{number of fourth graders}{number of groups}[/tex]  

  Insert the parameters and solve;

 Number of persons per group  = [tex]\frac{24}{3}[/tex]   = 8persons/group

12 cups of pineapple and 15 cups of orange juice

Step-by-step explanation:

1 batch=4 pineapple with 5 cups orange

3 batches=12 pineapple with 15 cups of orange juice

Answer:

First number: 20

Second number: 30

Step-by-step explanation:

First#:   x

Second#:   y

Constraints:

   x + y = 50      

   1/4x + 2/3y = 25

Isolate variable y:

   x + y = 50    

  -1/4 (x + y = 50 )

 -1/4x - 1/4y = -12.5

  Add equations the two equations to eliminate x:

    -1/4x - 1/4y = -12.5

     1/4x + 2/3y = 25

  _________________

       5/12y = 12.5

           5y = 150

              y = 30

Substitution to find x:

       x + y = 50  

       x + 30 = 50

              x = 20

Answer:

[tex]\sqrt{ \frac{{3V\pi } }{h}[/tex] = r

Step-by-step explanation:

V = 1/3 pi r^(2) *h

Rewrite:

V = pi * r^(2) * h/3

Inverse operations:

V / h / 3 = pi * r^2

Simplify:

3V/h = pi * r^2

Inverse operations:

3V/h / pi = r^2

Simplify:

3Vpi/ h = r^2

Inverse operations:

sqrt( 3Vpi/h) = r

[tex]\sqrt{ \frac{{3V\pi } }{h}[/tex] = r
