Answer:

  • the number of 1 bed-room apartment: 5
  • the number of 2 bed-room apartment: 7

Step-by-step explanation:

  • Let x is the number of 1 bed-room apartment
  • Let y is the number of 2 bed-room apartment

Given the information:

  • The total number of  apartments: 12
  • rent for one bedroom apartment: $360
  • rent for two bedroom apartment: $450
  • total monthly rental is $4,950

Hence, we can form two equations:

x + y =12 <=> x = 12-y (1)

360x + 450y = 4950 (2)

Let substitute (1) into (2), we have:

360(12-y) + 450y = 4950

<=> 4320 - 360y + 450y = 4950

<=> 90y = 630

<=> y = 7

=> x = 12-7 = 5

So, we have:

  • the number of 1 bed-room apartment: 5
  • the number of 2 bed-room apartment: 7

Hope it will find you well

According to the empirical rule, 68% of 7-year-old children are between ___ inches and ___ inches tall.
AveGali [126]

Using the empirical rule 68% would fall within one standard deviation of the mean.

The standard deviation is given as 2 inches and the mean is 49 inches.

Since it is only one standard deviation find the lower number by subtracting the standard deviation from the mean and find the higher number by adding the standard deviation to the mean.

49 - 2 = 47

49 + 2 = 51


68% would be between 47 inches and 51 inches tall.

URGENT! 100 POINTS TO SOLVE!
masya89 [10]

Answer:

20/5 = x /4 x = 80/5 = 16

x - 10 / 39 = 5/15 = 1/3

3x - 30 = 39

3x = 69

x = 23

(2x + 10 ) * 4 = 10 *(x + 3)

8x + 40 = 10x + 30

2x = 10

x = 4.

AE = 2(5) + 10 = 20, hope this helped.
