Answer:

x = 25

Step-by-step explanation:

<em>Step 1: Identify the similar triangles</em>

Triangle DQC and triangle DBR are similar

<em>Step 2: Identify the parallel lines</em>

QC is parallel to BR

<em>Step 3: Find x</em>

DQ/QB = DC/CR

40/24 = x/15

x = 25

Answer: x=25

Step-by-step explanation:

In order to calculate the value of "x", you can set up de following proportion:

\frac{BQ+QD}{QD}=\frac{RC+CD}{CD}\\\\\frac{24+40}{40}=\frac{15+x}{x}

Now, the final step is to solve for "x" to find its value.

Therefore, its value is the following:

1.6=\frac{15+x}{x}\\\\1.6x=x+15\\\\1.6x-x=15\\\\0.6x=15\\\\x=\frac{15}{0.6}\\\\x=25

Answer:

Step-by-step explanation:

Snorkel, mask, and flippers Slope: 2 (so in the equation, it would look like 2x).

Snorkel, mask, and flippers Y-intercept: 10 (12 - 2 = 10, which is 0 hours, possibly the initial amount)

Snorkel, mask, and flippers Slope intercept form: y = 2x + 10

Write children 3 and under free as an inequality
Valentin [98]

Answer:

Children ≤ 3 (are free)

Step-by-step explanation:

This is strangely worded by I think this is what you were looking for.

The key take away is, if it says something and under, you know it means that it can either be exactly that "something" or anything that is less than it, so you would use the less than or equal to symbol.

Triangle FCD is cut from parallelogram ABCD moved with left-hand side. What are the dimensions of the resulting triangle AEFD?
Ilya [14]

Answer:

The answer is below

Step-by-step explanation:

Triangle FCD is cut from parallelogram ABCD moved with left-hand side. What are the dimensions of the resulting rectangle AEFD?

A parallelogram is a quadrilateral (has four sides and four angles) in which opposite sides are parallel to each other.

A rectangle is a quadrilateral with opposite sides which are parallel and equal to each other. All the angles in a rectangle are at 90 degrees.

From the image, AD = z, FC = x, BF = w and BC = y. Hence:

EB = FC = x.

EF = AD = length = z; AE = FD = height = w

Therefore the dimensions of rectangle AEFD is length z and height w

Solve the inequality below. Use the drop-down menus to describe the solution and its graph.
aniked [119]

Answer:

x < -4

Step-by-step explanation:

Hello!

I don't see the drop-down menus, but I will try to help as best as I can...

Like any other equation, you are trying to get x by itself.

Our first step will be to subtract 13 from both sides.

-7x + 13 > 41

-7x > 28

Now, we will need to divide -7 from both sides. But, remember, dividing or multiplying a negative number will switch, or flip, the sign.

-7x/-7 > 28/-7

Doing the above equation will provide us with x all alone on one side:

x < -4

Hope I helped!

-Mary :)
