Lucy discovered that she owned one-third the number of pairs of blue jeans as she did t-shirts. Together, she owned 64 pairs of blue jeans and t-shirts. How many t-shirts did she own? A. She owned 32 t-shirts
B. She owned 16 t-shirts
C. She owned 48 t-shirts
D. She owned 54 t-shirts

C) 48 T-shirts

Step-by-step explanation:

The equation to find the amount of t-shirts is:

1/3x + x = 64

Add the Xs:

4/3x = 64

Multiply both sids by 3/4

Now:

x = 48 t shirts

To check:

64 - 48 = 16

16/48 = 1/3

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
