Mathematics
1 answer:
Nadya [2.5K]3 years ago
6 0

Answer:

see the explanation

Step-by-step explanation:

we know that

A mixed number is the sum of a integer and a fractional part

we have

7\frac{1}{5}+(-8\frac{3}{5})

so

7\frac{1}{5}=7+\frac{1}{5}

-8\frac{3}{5}=-8-\frac{3}{5}

substitute

7+\frac{1}{5}+(-8-\frac{3}{5})

Group terms

(7-8)+(\frac{1}{5}-\frac{3}{5})

(-1)+(-\frac{2}{5})

-1\frac{2}{5}

Rob is twice Joshua's age. Nick is 5 years older than Joshua. The sum of all their ages is 45. How old is Nick?
MatroZZZ [7]

Given

Rob is twice Joshua's age

Nick is 5 years older than Joshua.

sum of all their ages is 45.

Find the age of nick.

To proof

As given

Rob is twice Joshua's age

let  Joshua's age = x

than Rob age = 2x

Nick is 5 years older than Joshua.

Nick age = 5 + x

sum of all their ages is 45

than the equation becomes

Joshua's age + Rob age + Nick age = 45

put the value

x + 2x + 5 + x = 45

4x = 40

x = 10

Joshua's age = 10 year

than Rob age = 20 year

Nick age = 5 + 10

                = 15year

Hence proved
