whats the answer of the problem peter is 3 years older than his sister Anna. if times their combined age is 85 . determine Annas
jeyben [28]

Answer:

Anna is 41 years old.

Step-by-step explanation:

Easiest way to do this is by building a equation,

Lest say Anna's age is x.

Then as Peter is 3 years older than Anna Peter's age should be x+3.

Then the combined ages of the two people is given as 85. So we can write an equation as,

x+(x+3)=85

x+x+3=85

2x+3=85

2x+3-3=85-3 (deducting 3 from both sides of the equation)

2x=82

x=41

As we originally took Anna;s age as x

We can say Anna is 41 years old.

You go to a restaurant with 3 friends the total bill is 90 you pay 6% tax and add 20% tip what do you pay
vagabundo [1.1K]

The total bill (before tax and tip) = $90

Tax = 6% = 0.06

0.06 x $90 = $5.4

Tip = 20% = 0.20

0.20 x $90 = $18

$90 + $18 + $5.4 = $113.4 (Answer)
