A dinner check is to be split among 3 people. Greg’s portion of the check is twice Kelly’s. Joe’s portion is $1.50 less than 4 t
defon

Answer:

Kelly owes $16.5

Greg owes $33

Joe owes $64.5

Step-by-step explanation:

Let

Kelly's portion = x

Greg's portion = 2x

Joe's portion = 4x - 1.50

Total bill = $114.00

Total bill = Kelly's portion + Greg's portion + Joe's portion

114 = x + 2x + (4x - 1.50)

114 = 3x + 4x - 1.50

114 = 7x - 1.50

Add 1.50 to both sides

114 + 1.50 = 7x - 1.50 + 1.50

115.5 = 7x

Divide both sides by 7

x = 115.5 / 7

= 16.5

x = $16.5

Kelly's portion = x

x = $16.5

Greg's portion = 2x

= 2 × 16.5

= $33

Joe's portion = 4x - 1.50

= 4(16.5) - 1.50

= 66 - 1.50

= $64.5

Therefore,

Kelly owes $16.5

Greg owes $33

Joe owes $64.5

Find the length of side x. Show steps please!
yawa3891 [41]

Answer:

\large{x=7.4438\ cm\approx7.4\ cm}

Step-by-step explanation:

Use tangent:

tangent=\dfrac{opposite}{adjacent}

We have:

\alpha=28^o,\ opposite=x,\ adjacent=14\ cm

\tan28^o\approx0.5317

Substitute:

\dfrac{x}{14}=0.5317                <em>multiply both sides by 14</em>

x=7.4438\ cm
