X represents elga’s age
x+14+x=98
combine like terms
2x+14=98
subtract 14 from both sides
2x=84
divide both sides by 2 to isolate the variable (x)
x=42
elga is 42 years old.
if alvin is 14 years older than elga, and elga is 42, then alvin is 56 years old. 42+56=98

I will be really happy if you help me out! :)
kykrilka [37]

Answer/Step-by-step explanation:

#8. Using the geometric mean theorem formula, h = √xy, where,

h = x

x = 4 and y = 16

Plug in the values

x = √(4*16)

x = 8

#9. Using the geometric mean formula, h = √xy, where,

h = y

x = 5 and y = 8

Plug in the values into the formula:

y = √(5*8)

y = √40

y = 6.3 (nearest tenth)

#10. Using the geometric mean formula, h = √xy, where,

h = 18

x = 12 and y = y = ???

Plug in the values into the formula:

18 = √(12*y)

Square both sides

18² = 12y

324 = 12y

Divide both sides by 12

27 = y

y = 27
