Question

Larry is 72 inches tall. This is 50 inches than two times Mindy's height. What it Mindy's height

Answer 1

Let's understand the concept:-

• Here to find Mindy's height we need to take his age as x
• Then solve according to the question

Solution:-

Let Mindy's height=x

• According to the question

Larry's height=2×x+50=2x+50

ATQ,

`{:}\longmapsto`
`\sf 2x+50=72`

• Now take 50 to the other side

`{:}\longmapsto`
`\sf 2x=72-50`

• Simplify

`{:}\longmapsto`
`\sf 2x=22`

`{:}\longmapsto`
`\sf x={\frac {22}{2}}`

`{:}\longmapsto`
`\sf x=11`

`\therefore`
`\sf Mindy's \:Height \:is \;11 cm.`
