Atable and 8 chairs weighs 235.68lb together. if the table weighs 127.84lb , what is the weight of one chair in pounds?

From the information given, the total weight of table and 8 chairs is 235.68 lb.

The table only weighs 127.84 lb

Therefore the weight of the 8 chairs alone is 235.68 - 127.84 = 107.84 lb

The weight of one chair has not been given. Let us assume all the 8 chairs have  approximately the same weight. How much is the weight then of one chair?

We divide the total weight of 8 chairs by the number of chairs, so:

107.84 / 8  = 13.48

The weight of one chair is approximately 13.48 Ib

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
