Answer:
x = 16.5
Step-by-step explanation:
Use pythagorean theorem
a² + b² = c²
Plug in terms
7.1² + x² = 18²
Square each term
50.41 + x² = 324
Subtract a from c
x² = 273.59
Find square root
16.5
15% = 0.15
8 = 0.15x
8/0.15 = x
x = 53.33 or 160/3
The price would be $12.60 because 69.99 x 0.18 = 12.60
Answer: CURRENT AGES: C = 35, D = 5 AGES IN 5 YEARS TIME: C = 40, D = 10
Step-by-step explanation:
We need to use algebra here.
Let C = Coffee's age
Let D = Daughter's age
C = 7 x D
C + 5 = 4 x (D + 5)
C + 5 = 20 + 4D
C = 15 + 4D
7D = 15 + 4D
D = 5
C = 7 x 5
C = 35
