Answer:
Option D.
Step-by-step explanation:
The given system of equations is
...(1)
...(2)
On simplifying the second equation, we get
On dividing by -1, we get
...(3)
It is clear that equation (1) and (3) are same equations. It means equation (1) and (2) represent the equivalent equation.
So, the given system of equations has infinitely many solutions.
Therefore, the correct option is D.
Answer:
An assumption can be made that 70% of 25000 passengers will check one item of luggage
Step-by-step explanation:
So our equation to find this can be represented by 7x + 10 = 45.
(x representing miles run)
Just solve for x!
Subtract the 10 from both sides, you've got
7x = 35
And now to isolate the x, we divide both sides by 7.
Now we're left with just
x = 5!
We can check this by substituting 5 as x in our equation.
7x x 5 + 10 = 45
45 = 45
It's right!
So the runner ran 5 miles total.
Hope this helps!
If I skimmed over this too much, let me know and I'll try to explain the best that I can.
Hello!
To find the minimum number of weeks Jakob will need to wait if he saved 35 dollars per week, we would need to create an inequality equation.
Since he needs to save at least 700 dollars, it can be represented by the the greater than or equal to symbol. Also, the variable x, will be used in this equation representing the number of weeks. Then, we can create an equation for this problem.
35x + 175 ≥ 700 (subtract 175 from both sides)
35x ≥ 525 (divide both sides by 35)
x ≥ 15
Therefore, Jakob will have to wait a minimum of 15 weeks in order to save at least 700 dollars for a new computer.
