The answer you are looking for is

Solution/Explanation:

First, writing out the equation,

3x+5=2x-2x+29.

Next, making the equation more simple by subtracting 2x-2x, which is 0,

3x+5=0+29.

3x+5=29.

Now, subtracting 5 from both sides of the equation,

3x+5-5=29-5.

3x=24.

Finally, dividing both sides of the equation by 3,

3x/3=24/3.

x=8.

So, therefore, the final answer is x=8.

I hope this has helped answer your question. Enjoy your day, and take care!

Mrs Perry shares out 15 biscuites between Gemma and Zak in the ratio 1:4 How many biscuites do they get each? Gemma: Zak
kotykmax [81]
Number of biscuits shared by Mrs Perry = 25
ratio in which the biscuits were shared between Gemma and Zak = 1:4
Let us assume the common ratio = x
then
x + 4x = 15
5x = 15
x = 3
Then
The number of biscuits that Gemma got = 3
The number of biscuits that Zak got = 4x
                                                          = 4 * 3
                                                           = 12
So
Gemma: Zak = 3:12
I hope the procedure is clear enough for you to understand.

Select the most important variables and expressions the park owners should consider as they decide whether to add another roller
JulijaS [17]

Answer:

The park owners should take into account the population of children in the community, if there are a good number of kids living in that area and the towns nearby - there would be a great demand for another roller coaster. They should consider the safety measures on the particular roller coaster they intend to add and check for the available space where they plan to fit the ride in the park.

Hope that answers the question, have a great day!

The figure is composed of a rectangular prism and a triangular prism. Find the volume of the figure.
Darya [45]

<u>Given</u>:

The given figure is composed of a rectangular prism and a triangular prism.

The length of the rectangular prism is 30 inches.

The width of the rectangular prism is 14 inches.

The height of the rectangular prism is 14 inches.

The base of the triangle is 7 inches.

We need to determine the volume of the composite figure.

<u>Volume of the rectangular prism:</u>

The volume of the rectangular prism can be determined using the formula,

V=lwh

Substituting l = 30, w = 14 and h = 14, we get;

V=30 \times 14 \times 14

V=5880 \ in^3

Thus, the volume of the rectangular prism is 5880 cubic inches.

<u>Volume of the triangular prism:</u>

The volume of the triangular prism can be determined using the formula,

V=\frac{1}{2}bhl

where b is the base of the triangle,

h is the height of the triangle and

l is the length of the prism.

Substituting b = 7, h = 14 and l = 30, we get;

V=\frac{1}{2}(7)(14)(30)

V=1470 \ in^3

Thus, the volume of the triangular prism is 1470 cubic inches.

<u>Volume of the composite figure:</u>

The volume of the composite figure can be determined by adding the volume of the rectangular prism and the volume of the triangular prism.

Thus, we have;

Volume = 5880+1470

Volume = 7350 \ in^3

Hence, the volume of the composite figure is 7350 cubic inches.
