Tamara has two sisters. One of the sisters is 7 years older than Tamara. The other sister is 3 years younger than Tamara. The product of Tamara's sisters' ages is 24. How old is tamara?

Age of tamara=5years

Step-by-step explanation:

lets assume that age of tamara is Z and Tamara sister's age are X and y

according to Question:

one sister is 7 years older than tamara:

i.e. X=Z+7...........1

Other sister is 3 years younger than tamara:

Y=Z-3.....................2

product of tamara 's sisters age is 24

XY=24...........................3

multiply eqn1 and eqn2

put value of XY from eqn2

on solving this equation

Z=5, -9

we got two values of Z but one of them is negative and age can not be negative so

Z=5years

hence,

Age of tamara=5years

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d
