It raised $1.30
1.30/13.15 = .098
It raised 9.888%
(round as instructed by teacher)
Answer: 5
Step-by-step explanation:
sqrt of 100 = 10
10/2 = 5
Answer:
138
Step-by-step explanation:
According to PEMDAS (explains which operation you do first)
(Parentheses
Exponents
Multiplication or Division
Addition or Subtraction),
1. multiplication comes before addition
2. Even if it was 89+7x7, it would still be 7x7 first.
3. 7x7=49. Add it to 89 and you get 138
For this problem I would change:
2x + 3y = 25 into
-2x - 3y = -25
Then, I would add up both equations by lining them up top of another.
5x + 3y = 31
+ -2x - 3y = -25
3x = 6
x = 2
Now that you have x, solve for y.
5x + 3y = 31
5(2) + 3y = 31
10 + 3y = 31
3y = 21
y = 7
So, x is 2 and y is 7.
Check to see if the values are correct by plugging them into the other equation.
2x + 3y = 25
2(2) + 3(7) = 25
4 + 21 = 25
25 = 25
Since the values are correct, the solution to this problem is A (2, 7).
idk tbh so imma go with b because that is wut my gut says
