Answer:one solution
Step-by-step explanation:
x=-3, TeR
24=3r/4
Multiply both sides by 4
24=(3r)/4
(24)*(4)=(3r/4)*(4)
96=3r
Flip the equation
3r=96
Divide both sides by 3
3r/3=96/3
r=32
Now lets check if the answer is good
24=3(32)/4
24= 96/4
24=24
You see , the answer is good .
I hope that's help ! Let me know .
22 is the average of the numbers 20,17,24,18,29, and x is what I guess the qusetion is
count them
6 numbers
(20+17+24+18+29+x)/6=22
(108+x)/6=22
times both sides by6 to clear fraction
108+x=132
minus 108 from both sides
x=24

Answer:
Step-by-step explanation:
81
=
3
4
and
27
=
3
3
, so this equation can also be written as
3
4
x
=
3
3
(
x
+
2
)
=
3
3
x
+
6
.
Since the bases are now the same, we can equate exponents to get
4
x
=
3
x
+
6
so that
x
=
6
(technically this equating of exponents requires the fact that exponential functions (with base not equal to 1) are one-to-one functions).
