What is the value of x?

Answer:

20 inches longer

Step-by-step explanation:

78-58= 20

Answer:

Below in bold.

Step-by-step explanation:

To get a stratified sample you work out the proportion of girls from each school.

From  school A we take: (126/461) * 80 = 22 girls.

From B    :-      (82/461) * 80 = 14 girls.

From C  :-        (201/461)*80 = 35 girls

From CD  :-      (52/461)*80 =   9 girls.

[tex]\log_4 (2-x) = \log_4 (-5x-18)\\\\\implies 2-x = -5x -18\\\\\implies 5x -x = -18-2\\\\\implies 4x = -20\\\\\implies x = -\dfrac {20}4\\\\\implies x = -5[/tex]

Answer:

D. addition property

Answer:

D

Step-by-step explanation:

A root of f(k) is x=k. Option C is correct.The numbers we're multiplying are factors of the product since they're divisible by it.

A number is obtained by dividing another number by itself without leaving a leftover. To put it another way, if multiplying two whole numbers produces a product,

The factor of the f(x) is given as;

[tex]\rm (x+k)[/tex]

The factors satisfy the equation as;

[tex]\rm (x+k)=0 \\\\ x=-k[/tex]

Hence one root of f(x) is x = -k, The correct answer is option C.

Answer:

Option C

Step-by-step explanation:

Answer:

x < 3

Step-by-step explanation:

Your inequality: 4x - 1 < 11

4x - 1 < 11

Add 1 to both sides

4x < 11 + 1

4x < 12

**Don't switch signs because no negatives nor any specifications**

Divide 12 by 4

x < 3

Answer:

y = 3,224x + 750

Step-by-step explanation:

Assuming the scholarship and grants are applied using the slope intercept form y=mx+b where m is the slope in this case the cost per year attending x the number of years attended and b the y intercept which in this case is the one time fee subtracting 13,774 by 10,550 gives us 3,224.

Since the one time fee is only in place once that would make it the y intercept therefore y=3,224x+750 is the correct answer

Answer:

3 with an arrow pointing to the left

Step-by-step explanation:

The equations y = 3x - 4 and y = 3x + 1 are linear equations

The equations have no solution

The equations are given as:

y = 3x - 4

y = 3x + 1

Next, we plot the graph of the equations y = 3x - 4 and y = 3x + 1

From the graph (see attachment), we can see that the equations do not have a point of intersection

Hence, the equations has no solution

Step-by-step explanation:

You need to do distributive property to simplify the expression.  

3(2x+5) is your expression

You need to multiply 3 by 2x and 5

6x+15 is your final.

Therefore, D is the correct answer.

The circle and the lines AC & AB are illustrations of congruent angles

See below for the proof that the angles ∠ACB and ∠MAB are equal

To prove that ∠MAB=∠ACB, we make use of the attached diagram

From the attached diagram, we have:

∠MAB = x°

The angle at between a tangent and a radius or a diameter is a right angle.

This means that:

∠MAB + ∠BAC = 90°

Substitute ∠MAB = x°

x° + ∠BAC = 90°

Subtract x from both sides

∠BAC = 90° - x°

The angle at in a semicircle is a right angle.

This means that:

∠CBA = 90°

The angles in a triangle add up to 180°.

So, we have:

∠BAC + ∠CBA + ∠ACB = 180°

Substitute ∠CBA = 90° and ∠BAC = 90° - x°

90° - x° + 90° + ∠ACB = 180°

Evaluate the like terms

180° - x° + ∠ACB = 180°

Subtract 180° from both sides

- x° + ∠ACB = 0

Add x° to both sides

∠ACB = x°

Recall that:

∠MAB = x°

So, we have:

∠ACB = ∠MAB = x°

Hence, the angles ∠ACB and ∠MAB are equal

Step-by-step explanation:

The difference will usually be the first term subtracted by the second but it is the space/value between the numbers so technically you could just take the negative from b-a as -(b-a) and get the same value

Answer:

x=29

Step-by-step explanation:

divide by 2 first on both sides.

then put paranthesis on both sides and power it to the 2nd.

you get

(x-4)^2=5^2

simplify and you get x-4=25

add 4 on both sides and you get x=29!

Answer:

96 / 6 = 32 / 2 = 16 / 1 = 16 per pillow

Step-by-step explanation:

Answer:

$16

Step-by-step explanation:

To find the cost of a single pillow, you have to divide the total cost of the pillows ($96) by the number of pillows purchased (6).

96 / 6 = 16

Therefore, the cost per pillow, in dollars, is $16. I hope this helps! Have a lovely day!! :)

Answer:

  125 mL

Step-by-step explanation:

Susan's purple paint has the proportions 2 parts red and 3 parts blue. That means the total amount of paint is (2+3)/2 = 5/2 the amount of red paint, or (2+3)/3 = 5/3 the amount of blue paint.

__

The total amount of paint Susan has is 50 mL +100 mL = 150 mL.

If Susan uses all of her red paint (with sufficient blue paint), she would have an amount of purple paint equal to ...

  (5/2)(50 mL) = 125 mL . . . . purple paint

If Susan uses all of her blue paint (with sufficient red paint), she would have an amount of purple paint equal to ...

  (5/3)(100 mL) = 166 2/3 mL . . . . purple paint

This is more paint than Susan has, so the amount of purple paint Susan can make is limited by the amount of red paint she has. Susan can make a maximum of 125 mL of purple paint.

_____

Additional comment

Essentially, we have rewritten the proportion to show corresponding amounts of red and blue paint:

  red : blue = 2 : 3 = 50 : 75 = 66 2/3 : 100

Since Susan has only 50 mL of red, and more than 75 mL of blue, the red paint is the limiting ingredient.

Answer:

h = 46

Step-by-step explanation:

Have unknowns (h) on one side and knowns on other side.

-18 + h = 28       Add 18 on both side to move it to the right side.

h = 28 + 18

h = 46

Answer:

Step-by-step explanation:

Isolate the term of h from one side of the equation.

First, switch sides.

⇒ h-18=28

Add by 18 from both sides.

⇒ h-18+18=28+18

Solve.

Add the numbers from left to right.

⇒ 28+18=46

⇒ h=46

Rebekah reports the volume of sugar solution using metric system as 39.1 mL. Thus, option D is correct.

The metric system has been the measurement system introduced in 1790s. The system has mediated the units for the measurement of volume, mass, length.

The volume has been the space that has been occupied by matter. The volume can be denoted with SI unit L. However, the another accepted unit for volume has been mL.

Thus, the volume of sugar solution has been reported in mL.

The given sugar solution has volume of 1.32 fl. Oz

The volume in mL can be given as:

[tex]\rm 1\ fl\ oz=29.6\ ML\\\\1.32\ fl\ oz=-1.32\times 29.6\ ML\\\\1.32\ fl\ oz=39.1\ ML[/tex]

The volume of the sugar solution reported by Rebekah on the metric scale has been 39.1 mL. Thus, option D is correct.
