Answer:
how do you do this
Step-by-step explanation:
Answer:
x = 10
Step-by-step explanation:
You know z = x+4, so ...
3z -x/2 = 37 . . . . . . . . the given relation
3(x +4) -x/2 = 37 . . . . substituting for z
5/2x +12 = 37 . . . . . . .eliminate parentheses and simplify
5/2x = 25 . . . . . . . . . . subtract 12
x = 10 . . . . . . . . . . . . . multiply by 2/5
_____
<em>Check</em>
3z = 3·14 = 42
x/2 = 10/2 = 5
42 exceeds 5 by 37 . . . . true
Answer:
The numerator factors to
![(x + 2)(x - 1)](https://tex.z-dn.net/?f=%28x%20%2B%202%29%28x%20-%201%29)
The denomenator factors to
![(x + 4)(x - 1)](https://tex.z-dn.net/?f=%28x%20%2B%204%29%28x%20-%201%29)
Answer:
29
Step-by-step explanation:
The right triangle is isosceles triangle so we have the left angle of it is:
180-64=116
116÷2=58
Then start to calculate the left triangle angles:
180-58 = 122
180-122 = 58
58÷2 = 29
