The answer would be 56 4/10, or 56 2/5 simplified, because .4 into fraction form is 4/10.
Please make brainliest! ☺
Answer:
Step-by-step explanation:
In this problem you’d need to multiply 4 on the bottom equation to make -x into -4x and from there the 4x on the top equation and the -4x in the bottom equation cancel out. Don’t forget, if you are multiplying 4 on the bottom equation you have to distribute it to the other terms in that equation So the new bottom equation would look like this 4(-x - 3y =3) then distribute the 4 so -4x - 12y = 12. Once you cancel the x you can add the y and the answers from both equations. And find y from there.
Answer:
Yah no way man your gonna fail
Step-by-step explanation:
Tangent is the ratio opposite/adjacent
tan(angle) = opposite/adjacent
tan(x) = 8/5
tan(x) = 1.6
x = arctan(1.6)
x = 57.9946
x = 58 degrees which is the answer
The answer is approximate to the nearest whole number. Make sure your calculator is in degree mode.
