11+2x = 8*(x-5)

11+2x = 8x-40

11+40+2x = 8x-40+40

51+2x-2x=8x-2x

51 = 6x

51/6 = 6x/6

8.5 = x

Therefore, your number is 8.5.

HI can someone do these 5 problems? it will really help me out I'll give out brainliest to the person who answers them. (No link
Softa [21]

Answer:

$73.60

$345

simple interest = amount deposited x time x interest rate

600 + (600 x 0.055 x 5) = $765

600 + (600 x 0.055 x 5) > $2000

$765  $2000

He would not have $2000 in 5 years

Step-by-step explanation:

Total cost of items purchased = $75 + (2 x $8.50) = 92

If there is a 20% discount, he would pay (100 - 20%) 80% of the total cost =

0.8 x $92 = $73.60

commission earned = percentage commission x amount of sales

10% x $3450

= 0.1 x 3450 = 345

Amount he would have in his account = amount deposited + simple interest

simple interest = amount deposited x time x interest rate

600 x 0.055 x 5 = $165

Amount in his account in 5 years = $165 + 600 = $765

He would have less than $2000 in his account. he would have $765

Matthew is packing 120 pencils and 108 notebooks
Rasek [7]

9514 1404 393

Answer:

  • 12 boxes
  • 10 pencils, 9 notebooks

Step-by-step explanation:

a) The number of boxes will be the greatest common divisor (GCD) of the numbers 120 and 108. That number is 12.

  120 = 12×10

  108 = 12×9 . . . . 12 is the greatest common divisor

Matthew can make 12 boxes with equal numbers of the items.

__

b) 120 pencils divided by 12 will be 10 pencils per box.

108 notebooks divided by 12 will be 9 notebooks per box.

_____

<em>Additional comment</em>

It helps to be familiar with multiplication tables up to about 12×12.

The GCD can always be found using Euclid's algorithm. Look at the remainder when the larger number is divided by the smaller. If it is not zero, then replace the larger number with the remainder and repeat. If the remainder is zero, the divisor is the GCD.

Here, we have ...

  120/108 = 1 r 12.

  108/12 = 9 r 0   ⇒   12 is the GCD

The difference between the two mass is 151950g

Data;

  • Mass a = 29.48kg
  • Mass b = 181,430g
<h3>Difference Between The Mass</h3>

To calculate the difference between the mass, we must do so in the same unit. i.e both mass a and mass b must be in the same unit.

<h3>Conversion of Mass from Kg to g</h3>

Let's convert mass a from kg to g

1kg = 1000g

Using this, we can find how many grammes are in 29.48kg

1kg = 1000g\\29.48kg = x\\x = 29.48 * 1000\\x = 29480g

Now we can find the difference between mass b and mass a

b - a = 181430 - 29480 = 151950

The difference between the two mass is 151950g

Can I just get the answer for this I feel like it’s wrong.
Leya [2.2K]

The initial membership fee for Club A is; $2.5.

The initial membership fee for Club B is; $3.

Hence, Club A has a lower initial membership fee.

<h3>What is the initial membership fee for each Club?</h3>

It follows from the concepts of linear graphs that the interpretation of the initial membership fee is the y-intercept of the graphs given.

This is so because, it corresponds to the total cost at a point when the number of movies watched is; 0. That is, before any movie is watched.

Consequently, the graph calibrations (including the missing Club A graph) allow the determination of the initial membership fee (y-intercept) as declared above.

Ultimately, Club A has a lower initial membership fee.
