Answer: whats the answer???? I need it soo badd :((
Step-by-step explanation:
108-271+215-_____=-103
Im going to combine the first thee numbers and replace the blank with a variable, lets use x.
52 - x=-103
now I am going to subtract 52 on both sides to get the variable alone
-x=-155
Im going to multiply both sides to eliminate the negitive in the variable
x=155
If you want to check just plug 155 into the blank
108-271+215-155=-103
-163+215-155=-103
52-155=-103
-103=-103
so after checking work the blank is equal to 155.
36/7 = 27/x.....36 mm to 7m = 27 mm to x m
cross multiply
(36)(x) = (27)(7)
36x = 189
x = 189/36
x = 5.25 m

Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , thus
w = 180° - (90 + 31) °= 180° - 121° = 59°
y = 59° ( vertical angle to w )
w and v are adjacent angles, thus
w + v = 180°
59° + v = 180° ( subtract 59° from both sides )
v = 121°
x = 121° ( vertical angle to v )
Thus
v = 121°, w = 59°, x = 121°, y = 59°
