Answer:

The price of one ticket is $76.

Step-by-step explanation:

5% of $330 is $16.50 and 45% of $330 is $148.50. Add those two together and then add $13 to it. You should get 178 and subtract it from 330 which leads you to 152. It asks for the price of one ticket, so you divide that by 2 which results to $76.

Answer:

The error is in the second line.

x = -1

Step-by-step explanation:

When solving for "x", you are trying to isolate it, or move everything else to the other side. You may have learned that "what you do to one side, you do to the other" .

2x + 18 = 16

2x = 34               18 was added to the right side, but not to the other.

If you add 18 on both sides, then the equation would be:

2x + 36 = 34       "x" is not being isolated.

Instead, you should subtract 18 from 16.

Correct solutions steps:

2x + 18 = 16

2x + 18 - 18 = 16 - 18     Subtract 18 from both sides to cancel out 18

2x = -2

2x/2 = -2/2                     Divide both sides by 2

x = -1                              Final answer

-20

Explanation:

( − 7   ^ 2  −  4 )  +  ( − 7   ^ 2  −  6  − 2 )

Eliminate the redundant parentheses, subtract the numbers which will get you, combine like terms, rearrange terms, then your solution is:

− 1 4 2 −6 −6

Figure that problem out then you will get -20.

Answer:

−14x^2 − 6x - 6

Step-by-step explanation:

(−7x 2 −4)+(−7x 2 −6x−2) should be written as (−7x^2 −4) + (−7x^2 −6x−2).  The " ^ " symbol denotes exponentiation.  7x^2 means "7 times the square of x."  We can immediately remove the parentheses, obtaining:

−7x^2 −4 −7x^2 − 6x − 2

Our next step is to combine like terms.  For example, -7x^2 appears twice, with the same (negative) sign; summing these up results in -14x^2.

Immediately after doing that, we have:

−14x^2 −4 − 6x − 2

and need to combine the constants -4 and -2:

−14x^2 −6 − 6x

Finally, we write these terms in descending powers of x:

−14x^2 − 6x - 6

Answer: A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

The standard form of the given number is 983.7 x 10^6.

We have given that,

The screen displays 9.837E8. Write this number in standard form.​

We have to write the above equation in standard form.

The standard form of a number is a way of writing the number in a form that follows certain rules. Any number that can be written as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form.

We have given  9.837^8

Therefore the standard form of the given number is  983.7 x 10^6.

Answer:

The answer is 9.625

Step-by-step explanation:

So what you have is the area and the base of the rectangle. To find the height, just divide 4 into 38.5

38.5 / 4 = 9.625

To double check just multiple 9.625 by 4

9.625 x 4 = 38.5

Answer:

(- 2, 1 ) and (1, 4 )

Step-by-step explanation:

Given the 2 equations

y = - x² + 5 → (1)

- x + y = 3 → (2)

Rearrange (2) expressing y in terms of x by adding x to both sides

y = x + 3 → (3)

Substitute y = x + 3 into (1)

x + 3 = - x² + 5 ( subtract - x² + 5 from both sides )

x² + x - 2 = 0 ← in standard form

(x + 2)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 1 = 0 ⇒ x = 1

Substitute these values into (3) for corresponding values of y

x = - 2 : y = - 2 + 3 = 1 ⇒ (- 2, 1 )

x = 1 : y = 1 + 3 = 4 ⇒ (1, 4 )

Answer:

KM=JL=93 units

or KM=KN + MN= 8x-3

Step-by-step explanation:

The value of length of KM can be equal to either JL or obtained by adding KN = (3x + 1) and MN = (5x - 4) depending on the diagram.

An isosceles trapezoid has non parallel sides congruent.

In the isosceles trapezoid the diagonals are also equal.

There is a pair of parallel lines in an isosceles trapezoid.

In the 1st figure trapezoid JL and KM are diagonals.

If we take the JM and KL to be the parallel lines then the opposite sides can be  JK and LM

And N is the middle line or the mid segment.

In the figure 2

The value of length of KM is obtained by adding KN = (3x + 1) and MN = (5x - 4)

KM=KN + MN = (5x - 4) +(3x + 1)

KM=8x- 3

Answer:

The answer is C

Explain:

Solve for x in the first equation.

Add 4y to both sides of the equation

3x=12+4y

12y-9x=36

Divide each term by 3 and simplify

X=4+4y/3

12y-9x=36

Replace all occurrences of x with 4+4y/3 in each equation.

-36=36

X=4+4y/3

Since -36=36 is not true, there is no solution
