Answer:
x = 12
Step-by-step explanation:
-3x+12=48
-12 -12
*subtract 12 from both sides
-3x = 36
-3x/3 = 36/3
*divide 3 from each sides
x = 12
Answer:
x=25
Step-by-step explanation:
they are supplementary and adjacent, thus you do 4x-3+3x+8=180, simplify and get 7x+5=180, subtract 5 from 180 which is 175, then ending up with 7x=175 and 175/7 is 25.
Step-by-step explanation:
This solution is reasonable because equal slopes are parallel and negative reciprocals are perpendicular. Four right angles make up a rectangle, and this fulfills it
A(6) and D(-4) are solutions to the equations
(6)^2 < 81 | 36 < 81
(-4)^2 < 81 | 16 < 81
