Kazeer [188]

Answer:

Lily has 63 points and Nala has 49.

Step-by-step explanation:

Since Nala and Lily are playing a dice game where they score points, and after one round, the ratio of Nala's points to Lily's points is 7 to 9, if Nala has 14 more points than Lily, to determine how many points Lily has se you must perform the following calculation:

9 - 7 = 2

14/2 = 7

7 x 7 = 49

7 x 9 = 63

63 - 49 = 14

Therefore, Lily has 63 points and Nala has 49.

anzhelika [568]

Answer:

6\ polyphonic\ ringtones  and 1\ standard\ ringtone

Step-by-step explanation:

Let

x -----> the number of polyphonic ringtones

y ----> the number of standard ringtones

we know that

x+y=7

x=7-y -----> equation A

3.25x+1.50y=21 -----> equation B

Solve the system of equations by substitution

Substitute equation A in equation B and solve for y

3.25(7-y)+1.50y=21

22.75-3.25y+1.50y=21

3.25y-1.50y=22.75-21

1.75y=1.75

y=1\ standard\ ringtones

Find the value of x

x=7-1=6\ polyphonic\ ringtones
