Answer:
Answer:
A) 14
B)24
C)35
D)20
Explanation:
A) Let the number be x.
Thus, 3x + 7 = 49
3x = 49 - 7
3x = 42
x = 42/3
x = 14
B) let lily's age be y.
Since Hillary's age is 19 years.
So,
19 = ⅔y + 3
⅔y = 19 - 3
⅔y = 16
Multiply both sides by 3 to give ;
2y = 48
y = 48/2
y = 24.
Lilly's age = 24 years
C) let the number be z.
Thus,
2z - 20 = 50
2z = 50 + 20
2z = 70
z = 70/2
z = 35
D) Let the cost of the handbag be p and the cost of the wallet be q.
Each handbag costs $10 more than each wallet.
Thus;
Cost of handbag = p + 10
Since she bought 2 handbags and a wallet and spent a total of $60 on the handbags.
Thus;
2(p + 10) = 60
2p + 20 = 60
2p = 60 - 20
2p = 40
p = 40/2
p = $20
