Answer:
X=121
Step-by-step explanation:
Reorder √x + 20 so highest orders Term are first
20+√x=9
We need to group all the variables term on one side and constant term at the other side. Therefore move the term 20 to the other side of equation 20+√x=9
√x=9-20
√x=-11
Eliminate the root
X=121
what would you like me to do with these numbers????
X= your age
400-2x=244
-2x=-156
x=78
you are 78 years old
Answer:
44 degrees
Step-by-step explanation:
x
Let the supplement/compliment by
y
x+
y=90
Complimentary angles add up to 90 degrees.
x+3
y=180
Supplementary angles add up to 180 degrees, the other angle is thrice the other compliment.
Evaluating this as a system:x+y=90 Isolate x:x=90−y Input into the other equation:(90−y)+3y=180Combine like terms, isolate y and its coefficients:2y=90 Isolate yy=45 Input into the first equation:x+45=90 Isolate x:x=45 degrees
