X-18 = 17

Answer:

x=−20

Step-by-step explanation:

Step by Step Solution:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    x/5-(-4)=0

:

Rewriting the whole as an Equivalent Fraction

2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  5  as the denominator :

         -4     -4 • 5

   -4 =  ——  =  ——————

         1        5  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

x - (-4 • 5)     x + 20

————————————  =  ——————

     5             5  

Equation at the end of step

:

 x + 20

 ——————  = 0

STEP

:

When a fraction equals zero

3.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 x+20

 ———— • 5 = 0 • 5

  5  

Now, on the left hand side, the  5  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  x+20  = 0

Solving a Single Variable Equation:

3.2      Solve  :    x+20 = 0

Subtract  20  from both sides of the equation :

                     x = -20

One solution was found :

x = -20

Answer:

x=-4.5 or -9/2

Step-by-step explanation:

The first step is to isolate x to do this you add 5 to both sides which then gives you -2x=9 the next step is to divide by negative 2 which would give you -9/2 which simplifies to -4.5.

Step-by-step explanation:

the question should be : "which describes a POSSIBLE domain and range definition of the function and is inverse ?"

because this is just a matter of definition. the function itself would not suggest any limits.

and in that regard the function definition is basically irrelevant.

the domain of any basic function is the range of the inverse, and the range of the basic function is the domain of the inverse.

so, the second set of definitions is not possible, if we are really trying to define the inverse function.

Step-by-step explanation:

If the base is a square than you figure out what number multiplied by itself is equal to 144 and since a square has 4 side you do 12x4 which equals 48. P.S. 12x12 is 144!

Answer:

Step-by-step explanation:

If the angle measures x, then the supplement measures 180-x.

This means x-132.6=180-x, and thus x=156.3

This means the angles measure 156.3 and 23.7 degrees.

The amount of cardboard = Surface area of a triangular prism = 679.2 in.²

Surface area of a triangular prism = (perimeter of base × length of the prism) + (2 × Base Area)

= (S1 +S2 + S3)L + bh

The mailing tube is a triangular prism with an equilateral triangular base, and has the following given values:

Plug the values into the surface area formula to find the amount of cardboard that would be used to make the tube:

Amount of cardboard = Surface area of a triangular prism = (6 + 6 + 6)36 + (6)(5.2) = 679.2 in.²

Answer:

y= -2

Step-by-step explanation:

3y -15 =-21

add 15 to both sides

-15+ 15 =0 , -21+ 15 = -6

so we have

3y= -6

isolate y by dividing by 3 to each side and get

y=-2

Answer:

(-3, -6)

Step-by-step explanation:

The coordinate of point P is, (- 3, - 6)

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

We have to given that;

Point P partitions directed line segment AB in the ratio of 3 to 4.

And, A (-9, -9) and B (5,-2).

Now, The coordinate of Point P is find as;

⇒ P (x, y) = (3×5 + 4×- 9/ (3+ 4) , 3×-2 + 4×- 9 / (3 + 4) )

               = (15 - 36/7 , - 6 - 36/7)

               = (- 21/7, - 42/7)

               = (- 3, - 6)

Answer:

r = 1.7389 in

Step-by-step explanation:

(A) Volume of hollow block = 540 in^3

(B) volume of block without Hollows = b×d×h

= 6 ×16 ×8

= 768 in^3

(C) volume of 3 hollows = 3 ×( pi ×r^2 h)

= 3 ×( pi ×r^2 ×8)

= 24 ×pi ×r^2

solve,

A = B - C

540 = 768- (24 ×pi ×r^2)

r^2 = (768- 540) / 24 pi

r = root(3.023943919)

r = 1.7389 in

Answer:

(7,0)

Step-by-step explanation:

By Multiplying 4 and 7 (aka x), it will equal 28.

Multiplying 9 and y, (aka 0) , it will equal to 0

4(7)+9(0)=28

multiplying -4 by 7 will equal to -28 ,minus y which is 0, total will be -28

So $18 would be 120%. This is because the yoyo is 100% and you increased by 20%. If this was a calculator question, you would do 18 / 120 than times by 100 to get 100%. Naturally it would just be 18/12 x 10 = 15. so $15 is 100% or the originally price.

Hope it helped :)

The original price was $15.00

The price of the yo-yo increased by 20% and went to $18.00. Assuming the original price is x, the original price would be:

18 = x × (1 + 20%)

18 = x × 1.20

18 = 1.20x

x = 18 / 1.20

x = $15.00

In conclusion, the original price was $15.00 but after the price increased by 20%, it went to $18.00.

When it comes to fat, there's one type you don't want to cut back on: omega-3 fatty acids. Two crucial ones -- EPA and DHA -- are primarily found in certain fish. ALA (alpha-linolenic acid), another omega-3 fatty acid, is found in plant sources such as nuts and seeds. Not only does your body need these fatty acids to function, but also they deliver some big health benefits.
