Answer:
x=6
Step-by-step explanation:
81^x = 27 ^(x+2)
81 = 3^4 and 27 =3^3 so replace 81 and 27 in the equation
3^4^x = 3^3^(x+2)
When we have a power to a power we can multiply the exponents
a ^b^c = a^(b*c)
3^(4x) = 3^(3*(x+2))
Since the bases are the same, the exponents have to be the same
a^b = a^c means b=c
4x = 3(x+2)
Now we can solve for x
Distribute
4x = 3x+6
Subtract 3x from each side
4x-3x = 3x-3x+6
x = 6
Answer:
Just click an x on the graph for each number in the chart.
1/4 would have 4 x's
2/4 would have 2 x's
3/4 would have 1 x
1 would have 2 x's

18-72 equals -74
now -74 *10 equals-740
Answer:
2,400 meters
Step-by-step explanation:
4 × 60 sec = 240 meters a minutes
240 meters × 10 minutes = 2,400 meters in 10 minutes
1/8, 2/16, Equivalent fractions can be found by multiplying or dividing both the numerator and the denominator by the same number.
