B
Step-by-step explanation:
35 percent answer the quiz correctly
4 * 42 + 55 * x / ( 4 + x ) = 50.
The answer of x comes out to be 6.4. Which means that the truck will have to travel around 6.4 miles at an average speed of 55 miles to make it 50.
Well to understand how i constructed its equation is very simple. I equated the total average speeds answer to 50 and just calculated the average speeds with the help of algebra where x is the number of miles at 55 mph.
Answer:
The number of half-page advertisements is 4.
The number of Full-page advertisements is 11.
Step-by-step explanation:
According to the Question,
- Given, An advertising company charges $60 per half-page advertisement and $100 per full-page advertisement. Michael has a budget of $1340 to purchase 15 advertisements.
Let, 'x' be the number of half-page advertisements and 'y' be the number of full-page advertisements.
- Thus, 60x + 100y is the money charged, and given that he has a budget of $ 1340.
60x + 100y = 1340
- And, the number of advertisements is 15. So, the other equation is
x + y = 15
Now, We have Two Equations,
60x + 100y = 1340 and x + y = 15
- the solution of the system is Put x=(15-y) in Equation 60x + 100y = 1340
60 (15-y) + 100y = 1340
900 - 60y + 100y = 1340
40y = 1340 - 900
40y = 440
y = 440/40
y = 11 So, For x = 15 - y ⇒ 15-11 ⇒ x=4 .
- Thus, the number of half-page advertisements is 4 and The number of Full-page advertisements is 11 .
Answer:
x=334
Step-by-step explanation:
log(3x-2)=3
log(3x-2)=3
3x-2=10^3
3x-2=1000
3x=1000+2
3x=1002
x=1002/3
x=334
