you buy 6 roses for 2.45 each. 12 carnations for $.99 each and 9 tulips. your total cost is $40.08 how much does each tulip cost?

6 roses for $2.45 each.

6×2.45 = $14.70

12 carnations for $0.99 each.

12×0.99 = $11.88

9 tulips for ???

in total the price is $40.08 (incl. the tulips).

40.08 = 14.7 + 11.88 + 9×???

13.5 = 9×???

??? = $1.50

so, each tulip costs $1.50

your answer would be 10x - 1

x =-.20752

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
