Answer:

p = \frac{2}{5}

Step-by-step explanation:

3(5p - 3) = 5(p - 1)

<em><u>Try getting the x's all on one side</u></em>

15p - 9 = 5p - 5    <em>Start by adding 9 to both sides</em>

     + 9         + 9

15p = 5p + 4   <em>Then subtract 5p from both sides</em>

-5p   -5p

10p = 4     <em>Divide both sides by 10 to get p</em>

\frac{10p}{10} = \frac{4}{10}

p = \frac{4}{10} or \frac{2}{5}

On Monday, you run treadmill for 1/2 hour at x miles per hour. On Tuesday, you walk the same distance on the treadmill, at 2 mph
nikitadnepr [17]
Answer: 3

Explanation:

It is useful to summarise the information in the form of a table with columns for distance, speed and time.

Remember if you know two of these, you can write an expression or answer for the third one.

s = d/t and t = d/s and d = s × t

We have that the speed on Monday was x miles per hour and the time, 1/2 an hour. We can find the distance as x × 1/2

Show this on the table and then complete it for Tuesday as well.

Distance Speed Time
−−−−−−−−−−−−−−−−−−−−−−−−
Monday 1/2 x x 1/2
Tuesday 1/2 x (x-2) 3/4

The speed on Tuesday can be given in two ways:

It is the same as on Monday (1/2 x) or as s × t

Form an equation: 3/4 (x-2) = 1/2 x

4 x 3/4 (x-2) = 4 x 1/2 x ← x 4

3 (x-2) = 2x

3x - 6 = 2x

x = 6 ← this was the speed on Monday.

The distance run on Monday was 1/2 x 6 = 3 miles

so, the probability of students who choose calculators = 7/20

If there are 240 students in the Math club

What is the area of the composite figure? 262 cm2 264 cm2 266 cm2 268 cm2
miv72 [106K]

The Area is a two-dimensional scalar quantity. The area of the composite figure is 264 cm².

<h3>What is the area?</h3>

The area of a two-dimensional region, form, or planar lamina in the plane is the quantity that represents its extent. On the two-dimensional surface of a three-dimensional object, the surface area is its counterpart.

The composite figure can be broken down into four parts a square(A), a triangle(B) and two rectangles(C and D).

Now, if the area of the composite figure is taken out it will be,

\text{Area of composite}=\text{Area of Square A} + \text{Area of triangle B} + \text{Area of Rectangle C} + \text{Area of Rectangle D}\\

\text{Area of Composte}=(10^2)+(\dfrac12 \times 6 \times 4)+(8 \times 4)+(20 \times 6)\\\\\text{Area of Composte}= 100+ 12 + 32 + 120 =264\rm\ cm^2

Thus, the area of the composite figure is 264 cm².
