Answer: without parentheses it'll be : -2x square 2 2x square 2 9x-2!
Step-by-step explanation: well to start with,Nothing will change when you solve it just rember the PEMDAS and you'll be fine! Good luck :3
10x + 13y = 11....multiply by 3
3x + 14y = -27....multiply by -10
------------------
30x + 39y = 33 (result of multiplying by 3)
-30x - 140y = 270 (result of multiplying by -10)
-------------------add
- 101y = 303
y = 303/-101
y = -3
10x + 13y = 11
10x + 13(-3) = 11
10x - 39 = 11
10x = 11 + 39
10x = 50
x = 50/10
x = 5
solution is : (5,-3)
Answer:
7, 9, 11
Step-by-step explanation:
7+ 9+ 11 = 27.
7, 9, and 11 all fall right after each other when counting odd numbers, which makes them consecutive.
1 2/5 - (-3/5)
First, we're going to convert 1 2/5 into an improper fraction.
1 2/5 = 7/5
7/5 - (-3/5)
Subtracting a negative is the same as adding, so the problem will look like:
7/5 + 3/5
The denominators are the same, so we just add the numerators.
The answer is 10/5, or 2.
