Numero que multiplicado por si mismo de 50

Answer:

1st: 0 solutions

2nd: infinitely many solutions

3rd: 1 solution

Step-by-step explanation:

1st: add both equations and the result is 0 = 4 ⇒ inconsistent, no solution

2nd: add both equations and the result is 0 = 0 ⇒ it's true, for all x and y values

3rd: add both equations and obtain: 16x = 32 ⇒ x = 2,

then if you want to obtain y, replace x in any of both equations.

Conclusion is that only 1 solution (x = 2 and a unnique value for y) is obtained.

Answer:

103

Step-by-step explanation:

99+100+101+102+103=505

Answer: James had his gym membership for approximately 9 months.

Step-by-step explanation: To determine the number of months, m, James had his membership, we can set up an equation based on the given information.

The total cost of James' gym membership consists of two parts: the sign-up fee of $50 and the monthly fee of $65 multiplied by the number of months, m.

Therefore, the equation is:

Total cost = Sign-up fee + Monthly fee * Number of months

In this case, the total cost is $635, the sign-up fee is $50, and the monthly fee is $65. We want to find the number of months, which we will represent as m.

Plugging in the values, the equation becomes:

635 = 50 + 65m

Simplifying further:

635 - 50 = 65m

585 = 65m

To solve for m, we can divide both sides of the equation by 65:

m = 585 / 65

Calculating this division, we find:

m ≈ 9
