Please help me with the correct answer

Answer:

The first thing to do when solving an algebraic equation is the isolate the variable.  Thus, simply subtract 1/2x from both sides of the equation and subtract 5 from both sides to get [tex]-2=\frac{1}{2} x[/tex]

Answer:

Jackson is 12 and Shelly is 6.

Step-by-step explanation:

Since we know Jackson is two times older than Shelly, it only makes since for our answer to be 12.

to find this you can make two circles and add dashes in each until you reach 18, but add 2 to Jackson to each 1 you put for Shelly.

Answer:

32ft³

Step-by-step explanation:

Let the shape of the locker be cubic in nature.

Volume of a cube = L³

L is the side length of one of the lockers

Volume of four lockers = 4L³

If one side of the locker is 2feet long, then L = 2ft

Substitute into the formula;

Volume of four lockers = 4(2)³

Volume of four lockers = 4(8)

Volume of four lockers = 32ft³

Hence the total volume of all four lockers is 32ft³

To solve the problem we will calculate the volume of a single locker first.

The volume of the 4 lockers is equal to 32 ft³.

Given to us

one side of a locker is 2 feet long

Assumpting that the locker is of cube shape.

As it is given that the side of the locker is 2 feet long, and we know that all the sides of a cube are of the same length, therefore, the length of the side of the cube is 2 feet.

We know that the shape of the locker is cubic in nature, therefore,

The volume of the locker = Volume of the Cube

                                          = (Side of the cube)³

                                          = (2)³ = 8 ft³

Thus, the volume of a cubic locker is 8 ft³.

We have already calculated the volume of a locker, therefore, the volume of 4 such lockers will be 4 times the volume of a locker,

The volume of 4 lockers = 4 x  volume of a lockers

                                         = 4 x 8 ft³

                                         = 32 ft³

Hence, the volume of the 4 lockers is equal to 32 ft³.

Answer:

  80.5°

Step-by-step explanation:

The applicable trig function is the tangent.

  Tan = Opposite/Adjacent

In this scenario, the side opposite the angle is the tower height, 324 m. The side adjacent is the distance to the tower, 54 m. Then the angle α is related by ...

  tan(α) = 324/54

The value of the angle with this tangent is found using the arctangent function:

  α = arctan(324/54) ≈ 80.5°

She should set her binoculars to 80.5°.

Answer:

(3x^2+6x)/(x^2-16)

Step-by-step explanation:

When multiplying fractions you just go straight accross

this means that our fraction is equal to

((x+2)(3x))/((x-4)(x+4))

The numerator is quite easy 3x(x+2)=3x^2+6x

The second one is a little tough at first and if you need help I would reccomend using khan academy

but pretty much you get x^2-16

Answer:Meyer uses 2.5 loads

Step-by-step explanation:Why does he use 2.5? Because, he has 8 loads and with 1 load he covers 2/5 of his driveway so 2 loads covers 4/5 and 2.5 loads cover 5/5 of his driveway

Height = Volume / area of base

Area of base = 3.5 x 4 = 14 sq. inches.

Height = 84 / 14

Height = 6 inches.

yes that is true

Answer:

Her percent error was: ≈ 17% (whole percent)

Step-by-step explanation:

Given

Approximate value = 20 friends

Exact Value = 24 friends

To determine

Percent error

Using the formula to calculate the Percent error

Percent error = | Approximate Value| - Exact Value | / | Exact value | × 100

                       = | 20 - 24 | / | 24 | × 100

                       = | - 4 | / | 24 | × 100

Apply absolute value: |-a| = a,   a>0

                       = 4/24 × 100

                       = 16.67 %

                       ≈ 17% (whole percent)

Thus, her percent error was: ≈ 17% (whole percent)

Answer:

Tom's share = €800

Step-by-step explanation:

Given that:

Amount shared by Al, Tom and Joe = €3000

Ratio of Al's share to Tom's share = 5 : 4

Joe's share = 1.5(Tom's share) = 1.5(4) = 6

Therefore,

Ratio of Al, Tom and Joe = 5 : 4 : 6

Let,

x be the number of times of amount each get.

5x + 4x + 6x = 3000

15x = 3000

Dividing both sides by 15

[tex]\frac{15x}{15}=\frac{3000}{15}\\x=200[/tex]

Tom's share = 4x = 4(200) = €800

Hence,

Tom's share = €800
