Ben is 4 times as old as Ishaan and is also 6 years older than Ishaan.
How old is Ben?

Answers

Given :-

  • Ben is 4 times as old as Ishaan.

  • Ben is 6 years older than Ishaan.

To find :-

  • age of Ben

Let :-

  • Ishaan age be x
  • Ben age be 4x

Solution :-

✪According to question:-

Ben is 6 years older than Ishaan

So :-

  • Ben age - Ishaan age = 6 years

put supposed values

  • 4x - x = 6
  • 3x = 6
  • x = 6 ÷ 3
  • x = 6/3
  • x = (2 × 3)/3
  • x = 2/1
  • x = 2

Original Ages :-

  • Ishaan age = x
  • Ishaan age = 2 years

  • Ben age = 4x
  • Ben age = 4(2)
  • Ben age 4 × 2
  • Ben age = 8 years

✪Verification :

1st condition:-

  • Ben age - Ishaan age = 6 years

put original ages

  • 8 - 2 = 6
  • 6 = 6

LHS=RHS

Hence verified !

Required answer :-

Ben's age =8years

Write an expression to match the words " three times the sum of 8 and 4".

Answers

Answer: "Three times the sum of 8 and 4":3* (8+4)

Explanation:

In the question we have asked that what will be the mathematical expression for the " three times the sum of 8 and 4".

We have asked with 'Three times the sum of 8 and 4' which means that adding the sum of number '8' and number '4' by three times.

We can write 'Three times the sum' mathematically as '3 * (\text{sum of numbers})'.

We can write 'sum of 8 and 4' mathematically as '8+4

So the final expression comes out to be: 3*(8+4)
3(8+4) is your expression

When their report cards came back, Pete, Chris, and Dina realized that the number of A's they each received was in the ratio 4:2:5. If Pete got 14 more A's than Chris, how many A's did Dina get?

Answers

Answer:

The number of A's Dina got = 5/11 × 77 = 385/11 = 35

Step-by-step explanation:

The number of A's Pete , Chris and Dina received are in the ratio of 4:2:5.

Let the total number of A's = y

Total from ratio = 4 + 2 + 5 = 11

chris A's = 2/11 × y  

pete's A's = 2/11 × y + 14 = 4/11 × y

pete's A's

2/11 y + 14 = 4/11 y

14 = 4/11 (y) - 2/11 (y)

14 = 2/11 (y)

cross multiply

2y = 14 × 11

divide both sides by 2

y = 154/2

y = 77

Total number of A's = 77

The number of A's Dina got = 5/11 × 77 = 385/11 = 35

Answer:

35
