Answer:

x=5

Step-by-step explanation:

4(2x – 1) + 8 = 4x + 24.

Factor out a 4 from each side

4{ 2x-1 +2} = 4(x+6)

Cancel the 4 on each side

2x-1+2 = x+6

Combine like terms

2x+1 = x+6

Subtract x from each side

2x+1-x = x+6-x

x+1 = 6

Subtract 1 from each side

x+1-1 = 6-1

x = 5

harkovskaia [24]

Answer:

a. $395

b. $(350 + 0.15x)

Step-by-step explanation:

Her income in a week can be written as;

$350 + 15% of sales

a. In the case of $300 sales in a week

Mathematically, that would be;

$350 + 15% of $300

$350 + (15/100 * 300)

$350 + $45 = $395

b. In the case of $x in sales

= $350 + 15% of x

= $350 + (15/100 * x)

= $350 + 0.15x

= $(350 + 0.15x)

Find the area of the parallelogram.

tensa zangetsu [6.8K]

Answer:

Step-by-step explanation:

Area of a parallelogram = base × height

From the question

The base is = 30 cm

Let h represent the height of the parallelogram

We must first use Pythagoras theorem to find the height of the parallelogram before finding it's area

We have

${25}^{2} = {h}^{2} + {24}^{2} \\ {h}^{2} = {25}^{2} - {24}^{2} \\ {h}^{2} = \sqrt{ {25}^{2} - {24}^{2} } \\ {h}^{2} = \sqrt{625 - 576} \\ {h}^{2} = \sqrt{49}$

We have the answer as

h = 7 cm

So from the question

height = 7cm

Let's substitute the base and the height into the above formula and solve for the area

We have

Area = 30 × 7

We have the final answer as

Hope this helps you

1st set = 4 letters

2nd set = 4x 4 = 16 letters

3rd set = 16 x 4 = 64 letters

4th set = 64 x 4 = 256 letters

5th set = 256 x 4 = 1,024 letters

6th set =1024 x 4 = 4,096 letters

7th set = 4096 x 4 = 16,384 letters

8th set = 16,384 x 4 = 65,536 letters

Each letter cost 2

Total cost = 65,536 x 2 = 131,072
