3x + 2y = 39
5x - y = 13
Multiplying the last by two:
10x - 2y = 26
Adding to the first
13x = 65
x = 5
y = 5x-13 =25-13=12
Check:
3(5)+2(12)=39 good
5(5)-12=13 good
Answer: x=5, y=12
Answer:
No you can not it would come out as a decimal form.
Step-by-step explanation:
3 divided by 2 is 1.5 or 1 1/2
This is not divided evenly between each other
This proves that (no) anything that is a odd number can not be divided equally
Hope that helps
Answer:
-2150000
Step-by-step explanation:
I hope this right cause my head hurt doing that
You will have to use trig to solve this:
The side you have is adjacent to the known angle
The side you are looking for is opposite the known angle
^^^This means you need to use tan:
tan(24) = 
.445222 =
^^^input tan(24) into calculator, then multiply 12 to both sides to isolate and solve for x
5.3 ≈ x
Hope this helped!
Answer: x = 54
Explanation:
180 - 14 = 166
3x + 4 = 166
3x = 162
x = 162/3 = 54
