What is the answer to x?

Answer: the number must be placed in the box is 9

suppose: the number must be placed in the box is x

have:

5u + 3(4u - 6) = -3u -27 + 20u + x

⇔ 5u + 12u - 18 = -3u - 27 + 20u +x

⇔ 17u + 3u - 20u = -27 + 18 + x

⇔ 0 = x - 9

⇔ x = 9

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

Simplifying both sides gives 

17u - 18 = 17u - 27 + ▢.

Subtracting 17u from both sides gives

-18 = -27 + ▢. 

If the number in the box is anything but 9, then the equation cannot be true, and the original equation has no solutions. If the number in the box is 9, then the two sides of the original equation are equivalent, and all values of u are solutions to the equation.

Work Shown:

s = side length = 15 inches

SA = surface area of the cube

SA = 6s^2

SA = 6*15^2

SA = 6*225

SA = 1350

The surface area is 1350 square inches.

Note the formula has us compute the area of each square face, which is s*s = s^2. Then we multiply by 6 since there are 6 identical square faces on the cube.

Answer:

1350 [tex]in^{2}[/tex]

Step-by-step explanation:

A cube has six sides. To find the area of a square, multiply the length by itself:

15 x 15 = 225

Since each side is the same (because the box is a cube), simply multiply 225 by 6 (the number of sides on a cube):

225 x 6 = 1350

Answer:

32 free throws.

Step-by-step explanation:

It is given that,

Peter shot 40 free throws. He made 80% of his shots.

We need to find the fraction that is equivalent to 80%.

It means we have to find 80% of 40. It can be calculated as follows :

[tex]F=\dfrac{80}{100}\times 40\\\\=32[/tex]

80% of 40 is equivalent to 32 free throws.

Answer:

125yd

option b is correct

The height of the arch from the ground will be 125 yards.

Given information:

An architect is designing a commemorative steel arch in the shape of a parabola.

Parabola is vertically placed and its legs are 300 yards apart.

The focus of the parabola is 80 yards above the ground.

Let a be the distance of focus from the vertex of the parabolic arch.

So, the equation of parabola will be,

[tex]x^2=-4ay[/tex]

Assume the origin is placed on the vertex of the parabola.

So, the coordinates of the legs will be,

(-150, -(80+a)) and (150, -(80+a))

Satisfy the above point with the equation of parabola as,

[tex]x^2=-4ay\\150^2=4a(80+a)\\a^2+80a-5625=0[/tex]

Solve the above quadratic equation as,

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\a=\dfrac{-80\pm\sqrt{80^2+4\times 1\times5625}}{2}\\a=\dfrac{-80\pm170}{2}\\a=-125, 45[/tex]

The value of a can't be negative. So, [tex]a=45[/tex].

So, the height of arch will be,

[tex]80+a=80+45\\=125\rm\;yd[/tex]

Therefore, the height of the arch from the ground will be 125 yards.

Step-by-step explanation:

Answer:

Volume is the amount of space an object occupies. To determine the volume of any rectangular object, multiply the measurements of length, width, and height.

Volume = Length × Width × Height

Calculate the volume of this rectangular object.

Length = 3 cm

Width = 3 cm

Height = 12 cm

Volume = l × w × h

Volume = 3 cm × 3 cm × 12 cm

Volume = 108 cm3

Notice that the units for volume are cubic centimeters (cm3).

So 8 ÷ 25 = 0.32 and the units would be g/ cm3 . Other units of density could be g/L or g/ml or mg/ cm3 or kg/ m3 and the list could go on and on. Any unit of mass divided by any unit of volume.

Answer:

7/50 meter

Step-by-step explanation:

Total piece of string = 7/8 meter

Used string = 1/5 of the piece of string

Used string =

1/5 of 7/8 meter

= 1/5 × 7/8

= 7/40 meter

Balance = Total string - used string

= 7/8 - 7/40

= 35-7/40

= 28/40

Balance = 28/40 meter

cuts the rest into 5 equal parts. What is the length of the pieces.

28/40 ÷ 5

= 28/40 × 1/5

= 28 / 200

= 7/50 meter

Length of each piece = 7/50 meter

Answer:

0.5 3/5 5/8 65%

Step-by-step explanation:

Answer:

Your answer is 0.5, 3/5, 5/8, 65%.

Step-by-step explanation:

Convert all numbers to decimals:

0.5 = 0.5

5/8 = 0.625

65% = 0.65

3/5 = 0.6

Arrange the numbers accordingly: 0.5, 0.6, 0.625, 0.65. Hence, your answer is 0.5, 3/5, 5/8, 65%.

plugin values into the formula:

surface area = 2 ( LW + LH + WH)

                     = 2 ( 9*2  + 9*9  + 2*9 )

Answer:

The answer is 9

Answer:

Nine

Step-by-step explanation:

Given:

Cost of the trip to get into the park = $19.99

Brady bought a hot dog for $3.50 and spent $2.10 on gas money.

To find:

The total money Brady spend.

Solution:

It is clear that,

Total money he spend = Cost of the trip to get into the park + Cost of a hot dog + Amount he spent on gas money

On substituting the values, we get

Total money he spend = $19.99 + $3.50 + $2.10

                                      = $25.59

Therefore, the total money Brady spend is $25.59.
