Jack was 11 years older than percilla together their age is totaled 155 years what were their ages

Percilla's age is 72.

Jack's age is 83.

Step-by-step explanation:

Let x: age of Percilla. The age of Jack in terms of Percilla's age is . Then the sum of Jack's and Percilla's ages can be expressed as:

We can apply inverse operations, so we take 11 on both sides and the equation remains unaltered. Remember that :

Now, we divide by 2 on both sides:

Therefore Percilla's age is 72 and Jack's age is 72+11=83.

i suppose it should be (y=2x-5)

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :
