Nadia spent 1/4 of her money on a shirt and 2/5 on new shoes. what fraction of nadia's money has been spent? what fraction of her money is left

13/20

Step-by-step explanation:

1/4 plus 2/5=

1/4 2/5

4 time 5= 20

5 time 1= 5

4 time 2= 8

8/20+5/20=13/20

step-by-step explanation:

$11.01

$16

$15

$4

hope this

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
