2 x length + 2 x width = perimeter.
2(2s-5) + 2(4s-13) = 108
Simplify:
4s-10 + 8s-26 = 108
Combine like terms:
12s - 36 = 108
Add 36 to both sides:
12s = 144
Divide both sides by 12:
s = 144/12
s = 12
Now replace s with 12 in each equation:
2(12) - 5 = 24-5 = 19
4(12) - 13 = 48-13 = 35
The answer is d. 35,35, 19,19
3x-x+2=4, That should be your answer if that is what your looking for
Essentially, you're going to want to reverse the steps on x in order to isolate it from the rest of the variables. To do this, perform inverse operations on x. The first one of these is the multiplication of x and m, so divide both sides by m to cancel m out on the right side. Now we have y/m = x + b. The final thing to do in order to isolate x is to subtract b from both sides. This yields us y/m - b = x. This can be rearranged into x = y/m - b, which should be your answer.
To the nearest thousand, it is 8,000
To the nearest hundred, it is 7,900
To the nearest ten, it is 7,930
Hope that helped :)
This means that it is 8x-28=15+x. We let x equal the number. You can solve for the equation.
