Answer: A, arithmetic
Step-by-step explanation:
An arithmetic sequence has a constant difference between each term. If she spend 36 dollars each week, the first week would be 36 the second week would be 72, and so on.
Given:
An exam starts at 10:10 and lasts for 75 minutes.
To find:
The time when the exam end.
Solution:
We have,
Starting time = 10:10
Exam duration = 75 minutes
First we will divide the 75 minutes in two parts 50 minutes and 25 minutes.
We know that 50 minutes after 10:10 is 11:00 and 25 minutes after 11:00 is 11:25. So,
10:10 + 75 minutes = 10:10 + 50 minutes +25 minutes)
= (10:10 + 50 minutes) +25 minutes
= 11:00 +25 minutes
= 11:25
Therefore, the exam ends at 11:25.
The solutions to the equation are 
.
You can find the answer to any quadratic by using the quadratic formula. The formula is below.
Then find a (the number attached to x^2), b (the number attached to x) and c (the constant). This will allow you to plug in and solve.
Sure what can I help with?
X + y = 250
y + 40 = x
x + y = 250
y = x - 40
x + y = 250
- x + y = - 40
2y = 210
y = 105
