Answer:

4th term = -5.

Step-by-step explanation:

a1 = 2

an = 2an-1 - 3

So a2 = 2*2 - 3 = 1

and a3 = 2*1 - 3 = -1

and a4 = 2*-1 - 3 = -5.

Answer:

The value of x is 5

Step-by-step explanation:

In the given triangle

∵ A segment joining two points lie on the two side

∵ This segment is parallel to the third side

∴ This segment divides the two sides into parts that have the same ratio

→ That means x over 2x - 3 equal to 10 over 14

∵ \frac{x}{2x-3} = \frac{10}{14}

→ By using cross multiplication

∴ 10 × (2x - 3) = x × 14

∴ 10(2x) - 10(3) = 14x

∴ 20x - 30 = 14x

→ Add 30 to both sides

∵ 20x - 30 + 30 = 14x + 30

∴ 20x = 14x + 30

→ Subtract 14x from both sides

∵ 20x - 14x = 14x - 14x + 30

∴ 6x = 30

→ Divide both sides by 6

∴ x = 5

∴ The value of x is 5

Answer:

More than 10% of Gillway students earned honors.

Step-by-step explanation:

<u>Step 1: Find the number of students who earned honors</u>

43 + 17 = 60

<u>Step 2: Find the total number of students</u>

381 + 108 = 489

<u>Step 3: Find the percentage of students who earned honors</u>

Students who earned honors/Total students x 100

60/489 x 100

12.27%

<u>Step 4: Find the correct answer</u>

Just under 11% of Gillway students earned  honors.

<em>This is incorrect since the percentage is more than 11%.</em>

Just over 11% of Gillway students earned honors.

<em>This is incorrect as just over 11% would mean somewhere between 11 and 12% whereas the actual percentage is just over 12%.</em>

More than 10% of Gillway students earned honors.

<u><em>This is correct as compared to all other statements since 12.27% is more than 10%.</em></u>

Almost 11% of Gillway students earned  honors.

<em>This is incorrect since almost 11% means less than 11% whereas the actual percentage is more than 11%.</em>

7.8 X 103<br>--------------<br>1.2 X 104<br>​
Strike441 [17]

;-;

Let's just do a bunch of math below.

7.8 X 103          ?

-------------- =    ------

1.2 X 104           ?

So, first, we're gonna do 7.8 multiplied by 103 to get 803.4.

Thus....

7.8 X 103         803.4

--------------   =  -----------

1.2 X 104              ?

Then we would do 1.2 multipied with 104 to get a product of 124.8.

Therefore....

7.8 X 103         803.4

--------------   =  -----------

1.2 X 104           124.8

Dividing 803.4 by 124.8 would get you a quotient of 6.4375.

Your answer is 6.3475.~

Have a nice day~
