8(3x-2)-8x=9(2x-6) find x
Answers
Answer:
x=19
Step-by-step explanation:
8(3x-2)-8x=9(2x-6) Distribute.
24x-16-8x=18x-54 Combine like terms.
16x-16=18x-54 Subtract 16x from both sides (getting rid of a variable first
-16x -16x is easier).
-16=2x-54 Add 54 to both sides.
+54 +54
38=2x Divide both sides by 2.

A newspaper is launching a new advertising campaign in order to increase the number of daily subscribers. The newspaper currently (t0) has 26,000 daily subscribers and management expects that number, S(t), to grow at the rate of subscribers per day, where t is the number of days since the campaign began. How long (to the nearest day) should the campaign last if the newspaper wants the number of daily subscribers to grow to 49,000?
Answers
Answer:
57 days
Step-by-step explanation:
Given that:
t(0) = 26000
Growth rate (S'(t)) = 80t^1/2
Targeted number of subscribers = 49000
Take the integral of the growth rate :
∫80t^1/2dt = [(80t^(1/2 + 1)) / 1/2 + 1] + C
[(80t^(1/2 + 1)) / 1/2 + 1] + C = (80t^3/2) / 3/2 + C
(80t^3/2) * 3/2 + C = (160/3)t^3/2 + C
(160/3)t^3/2 + C
Let C = t(0)
(160/3)t^3/2 + 26000 = 49000
(160/3)t^3/2 = 49000 - 26000
(160/3)t^3/2 = 23000
Multiply both sides by 3/160
t^3/2 = 23000* 3/160
t^3/2 = 69000/160
t^3/2 = 431.25
t^(3/2 * 2/3) = 431.25^2/3
t = 57.080277
t = 57 days (approx.)

In an office building, 39 offices are currently being rented. This represents 30% of the total units. How many offices are there in the building?
There are __ offices in the building
Answers
Answer:
130 offices are in the building
Step-by-step explanation:
first 39/x = 30/100
secondly, you cross multiply 39 x 100 and 30 x x
100 x 39= 3900
3900/30 = 130
Answer:
ANS. = 130
30% or 30/100=39offices
use cross multiplication
100/30 x 39/1 (note 30/100 is inversed to 100/30) math. law
10/3 x 39/1 (using divisor 10)
10/1 x 13/1 (using divisor 3)
10 x 13 = 130
Ans = 130 offices
Ans.Checked
30% of 130 offices
30/100 x 130/1
3/10 x 130/1 (10 as divisor)
3/1 x 13/1 (10 as divisor)
3 x 13 = 39
39 offices

Now from the given histogram following informations are extracted-
Number of students got 1 answer incorrect = 2
Number of students got 2 answer incorrect = 3
Number of students got 3 answer incorrect = 4
Number of students got 4 answer incorrect = 1
Number of students got 5 answer incorrect = 2
Thus from above we can conclude that,
Number of students got 3 answer incorrect = 4
Thus, the number of students got 3 answers incorrect is 4.
