Write a first step question and answer. then solve the problem. jerome bought 8 packs of baseball cards at a garage sale. each pack has 10 cards. he gave his younger sister 3 cards from each pack. how many cards does jerome have left?

Jerome has left 56 cards.

Explanation:

Since we have given that

Number of packs of baseball cards at a garage sale = 8

Number of cards in each pack = 10

Total number of cards in all is given by

Now,

He gave his younger sister 3 cards from each pack ,

So,

Number of cards he gave to his younger sister from each pack = 3

Number of packs were there = 8

So,

Total number of cards he has given to his younger sister is given by

So, number of cards left to Jerome is given by

So, there are 56 cards Jerome left with .

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
