Which equation is equivalent to 3(1 – x) = 2x - (6x+3)?

Answers

Answer:

3-3x=-4x-3

Please correct me if I am wrong.

Step-by-step explanation:

Option A is equivalent to 3(1 – x) = 2x - (6x+3) That is :

3 – 3x = -4x+3

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

The given equation is :

3(1 – x) = 2x - (6x+3)

multiply 3 with inside the parenthesis in the left side of equation :

3 – 3x = 2x - (6x+3)

subtract 2x with 4x and simplify :

3 – 3x = 2x - 6x+3

3 – 3x = -4x+3

this result is equivalent to option A which will give the same result.

Therefore, Option A is equivalent to 3(1 – x) = 2x - (6x+3).

Step-by-step explanation:

Given is the cyclic quadrilateral.

Opposite angles of cyclic quadrilateral are supplementary:

m∠U + m∠W = 18014 + 4x + 6x - 14 = 18010x = 180x = 18m∠V + m∠T = 18015y - 4 + 12y - 5 = 18027y = 189y = 189/27y = 7

U and w are opposing so supplementary

14+4x+6x-14=18010x=180x=18

Same efor V and T

15y-4+12y-5=18027y-9=18027y=189y=7

Find the value of YZ

Answers

Answer:

YZ = 44

Step-by-step explanation:

Let the intersection of XW and YZ equal A. For this problem, we can use power of a point in the scenario where two secants intersect in the interior of a circle. We get the equation:

WA * AX = ZA * AY

We can substitute the values we are given to get:

(2x - 6)(21) = (x + 1)(30)

42x - 126 = 30x + 30

12x - 126 = 30

12x = 156

x = 13

Using segment addition postulate, we can say that:

YZ = YA + AZ

And we can plug in what we know from the diagram:

YZ = 30 + x + 1

We can also plug in the value of x, 13

YZ = 30 + 13 + 1 = 44

Laura is walking for a local charity She earns 75 cents for every lap she walks How much does she earn for walking 50 laps

Answers

Answer:

She earns $ 37.5 by walking 50 laps

Step-by-step explanation:

This method is called unitary method.

If we know the value of 1 unit of an item we can calculate any number of units of item.

For 1 lap she earns 75 cents.

She walks 50 laps.

She earns for 50 laps = 50*75= 3750 cents

Now we have to converts cents into Dollars for convenience.

1$ = 100 cents

3750 /100 = $ 37.5

Answers

Complete question :

Colleen and Caroline each built a rectangle out of square tiles placed in 3 rows of 5. Colleen used tiles that measured 1 2/3 cm in length. Caroline used tiles that measured 3 1/3 cm in length.

a. Draw the girls’ rectangles, and label the lengths and widths of each.

b. What are the areas of the rectangles in square centimeters?

c. Compare the areas of the rectangles.

Answer:

Colleen = 41.667 cm²

Carolina = 166.667 cm²

Carolina's rectangle is larger Than Collen's

Step-by-step explanation:

To start with, we determine the total number of tiles used

3 Rows of 5 ; 3 in 5 places = 15

Length of collen's square tiles : 1 2/3 = 5/3

Area of collen's square tiles = square of side length, = (5/3)² = 25/9

Area of rectangle formed = area of square * number of tiles

(25 /9) * 15 = 41.667 cm²

Length of carolina's square tiles : 3 1/3 = 10/3

Area of collen's square tiles = square of side length, = (10/3)² = 100/9

Area of rectangle formed = Area of square * number of tiles

(100/9) * 15 = 166.667 cm²

Carolina's rectangle is larger Than Collen's

A drone builder states in their terms of conditions that the battery for their foldable drone will last for more than 4 hours of continuous flight-time if the battery was fully charged before the flight. To test this, claim a sample of n = 10 drones were tested. The results showed a sample mean of 4.2 hours and a sample standard deviation of 0.4 hours. Conduct the hypothesis test using a 0.5 level of significance and determine whether or not the manufacturers claim is supported.

Answers

Answer:

The manufacturer's claim is not supported

Step-by-step explanation:

The time duration the battery of the foldable drone is said to last, μ = 4 hours

The number of drones that were tested, n = 10 drones

The sample mean, [tex]\overline x[/tex] = 4.2 hours

The standard deviation, s = 0.4 hours

The hypothesis test level of significance = 0.5

The null hypothesis, H₀; μ = 4

The alternative hypothesis, Hₐ; μ ≠ 4

The test statistic is given as follows;

[tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s }{\sqrt{n}}}[/tex]

We get;

[tex]The \ test \ statistic, \ t =\dfrac{4.2 - 4}{\dfrac{0.4}{\sqrt{10} } } \approx 1.58113883008[/tex]

Therefore, the test statistic, t ≈ 1.58

The degrees of freedom, d. f. = n - 1

For n = 10, we have;

The degrees of freedom, d. f. = 10 - 1 = 9

From the t-table at 0.5 level of significance, the critical-t = 0.7

Given that the test statistic is larger than the critical-t, we reject the null hypothesis and there is enough statistical evidence to suggest that the manufacturer claim is not supported and that the mean is not 4 hours as claimed.

Ayoub is driving to France for his holiday.

He will drive a total distance of 300 miles. Ayoub sets off at 07:15.

It takes him 2.5 hours to travel the first 125 miles.

Use this information to estimate the time Ayoub will arrive.

Answers

Answer:

10:30 hours

Step-by-step explanation:

Total distance=300 Miles, Start Time=07:15

Distance travelled so far is 125 miles for 2.5 hours

First we need to calculate Ayoub's speed as follows

Speed=Distance/Time

=125miles/2.5hour

=50 miles/hr

The calculate the remaining distance

=300-125

=175 Miles

Assuming that Ayoub Travels in the same speed at the first 300 miles, the time he will use to cover the remaining 175 miles is

Time=Distance/speed

Substituting the values

Time=175/50

=3.5 hours

The time he will arrive at Paris is

07:15+03:30

=10:30 hours

Average speed is calculated by taking the total distance divided by total time taken

Total distance =32.5+100

Total time=2+0.5

Average speed=132.5/2.5
