Hello there!
2x - 7 = 3
Solve for x
2x = 3 + 7
2x = 10
x = 10/2
x = 5
Therefore, the number of x in the equation is 5
Let me know if you have additional question!
Answer:30
Step-by-step explanation:
Answer:
Step-by-step explanation:
2x(x - 3) + 7(x - 3)
2x^2 - 6x + 7x - 21
reduce
2x^2 + x - 21
if this is equal to 0 then:
2x^2 + x - 21 = 0
factored:
(2x + 7)(x - 3) = 0
How that was done:
Divide the (2x^2) into (2x) and (x).
Divide the (-21) into (+7) and (-3). You choose these numbers so that their sum, when multiplied by (2x) and (-3), adds up to (+x).
Answer:
<u>69 years</u> after 2005 which is in <u>2074</u> year the average price of a studio in this city will reach $1081.10.
Step-by-step explanation:
Given:
Average Price to rent a studio is denoted by 'p'.
It is been approximated by equation:

where t ⇒ number of years since 2005
Now given:
Average Price to rent a studio p = $1081.10
Substituting the value of p in above equation we get;

Solving the new equation to find the value of t we get;

Dividing both side by 24.1 we get;

Hence<u> 69 years</u> after 2005 which is in <u>2074</u> year the average price of a studio in this city will reach $1081.10.
