First equation is: x - y = 12
x = 12 + y
Now, substitute this in 2nd equation,
2x - 3y = 27
2(12+y) - 3y = 27
24 + 2y - 3y = 27
-y = 27 - 24
y = -3
In short, Your Answer would be -3
Hope this helps!
Answer:
387 and 388
Step-by-step explanation:
775 / 2 = 387.5
387 and 388
Answer:
x=76 degrees
Step-by-step explanation:
< dij + < jih = 180 straight line
< dij + 107 = 180
subtract 107 from each side
< dij = 73
<jdi + < dij + <idj = 180 triangle
31 + 73 + < idj = 180
combine like terms
104+ < idj = 180
subtract 104 from each side
< idj = 76
<idj = < ajf vertical angles
76 < ajf
<ajf = x
x=76 degrees
Answer:
1. Positive, 2. negative, 3. 16.8-(-28.1), Final answer -44.9.
Step-by-step explanation
Tryna cheat off the I-ready diagnostics huh
The highlighted sector is exactly 3/4 of the circle area, because 
is 3/4 of 
which is a complete rotation.
Since you are given the radius, you can compute the area as
So, 3/4 of this area would be 
squared cm.
The remaining sector, of course, is 
squared cm.
