Two lines, A and B, are represented by the equations given below:Line A: x + y = 2
Line B: 2x + y = 4
Which statement is true about the solution to the set of equations?
There are infinitely many solutions.
There are two solutions.
There is one solution.
There is no solution.
Answers
x + y = 2 ... y = 2 - x
2x + y = 4
_________________
2x + (2 - x) = 4
2x - x = 4 - 2
x = 2
y = 2 - x = 2 - 2 = 0
(x, y) = (2, 0)
The correct result would be: There is one solution.

4.5 + 4 1/2 so for the first part it is a fraction 4.5/15 you then multiply this to 5/8 and get 225/120 which you can then simplify to 3/16 then you work out 3 divided by 16 and get 0.1875 and multiply this decimal by 100 to get the percentage, 18.75%.

Answer:
2.
Step-by-step explanation:
Given that function is polynomial, each zero is contained in binomials of the form (x - a), where a is the value of the zero. The number of roots means the number of binomial and the grade of the polynomial. Then, the function has the following form:
In cosequence, the right answer is 2.
x-8 = 0 ⇒ x = 8
x-7 = 0 ⇒ x = 7

I'm guessing you mean to say that sum of 5 consecutive odd numbers is 135. In that case, let x be the first number. Then
x + (x + 2) + (x + 4) + (x + 6) + (x + 8) = 135
5x + 20 = 135
5x = 115
x = 23
So the numbers are 23, 25, 27, 29, and 31.
If you really did mean 555 consecutive odd numbers summing to 135,135,135, the process is the same, but you would find a non-integer solution so that wouldn't be possible.

Total meals: 23.50 + 40.65 + 30.50 + 15.68 = $110.42
Percentage =
Final answer:
James received an average tip of 16% for the meals he served, calculated by dividing his total tips by his total bill amount and multiplying by 100.
Explanation:
To solve this problem, we first need to find the total amount of bills that James served, which is $23.59 + $40.65 + $30.50 + $15.68 = $110.42. James received a total of $17.67 in tips. The percentage of tips James received can be calculated by dividing the total amount of tips by the total amount of bills he served and then multiplying that result by 100 to get the percentage. So, the calculation would look like this:
($17.67 / $110.42) × 100 = 16.01%
Rounding to the nearest percent, James received an average of 16% tip for serving these meals.
