18(2a-b)-4(2a-b)-13
=36a-18b-8a+4b-13
Rearrange
=36a-8a-18b+4b-13
=28a-14b-13
Answer:
Option A. 0.20
Step-by-step explanation:
Observations from the given frequency table are :
Total number of beds sold at Cloud Nine Furniture = 3 + 6 + 4 + 2
= 15
Number of twin beds sold = 3
Then, probability that the next bed sold will be a twin bed,


= 0.20
Therefore, the probability that the next bed sold is a twin bed will be 0.20 or 20%.

Answer:
11 dimes, 17 nickels
Step-by-step explanation:
d + n = 28, put one variable by itself on a side, d = 28 - n
.10d + .05n = 1.95
Sub the first equation into the second
.10(28 - n) + .05n = 1.95
2.8 - .10n + .05n = 1.95
2.8 - .05n = 1.95
-.05n = -0.85
n = 17 nickels
d + 17 = 28
d = 11 11 dimes
Answer:
The number of employees in 8 years is 442
Step-by-step explanation:
Given:
Decreasing rate = 7%
Current number of employees = 790
To Find:
The number of employees after 8 years is this same rate continues =?
Solution:
Let the number of employees after 8 years be x
The current number of employees is:
---------------------------------(1)
since the decrase rate is 7% we use 0.07
So after 8 years , eq (1) can be rewritten as



x= 442.005
x= 442 (approx)
