Help........Write an equation and solve:
Tom [10]

Answer:

5 months

Step-by-step explanation:

Equate the formulas for the weights of the two boys:

J's weight = 120 lb + (10 lb/mo)m  = D's weight = 150 lb + (4 lb/mo)m

Solve as follows:  Subtract 120 lb from both sides:

(10 lb/mo)m = 30 lb + (4 lb/mo)m.

Then:  (6 lb/mo)m = 30 lb, and m = (30 lb) / (6 lb/mo) = 5 months

Calculate the width of a 80” TV if the TV has an aspect ratio of 21:9.
blagie [28]

Answer:

34.29 Inch.

Step-by-step explanation:

The Aspect Ratio of a screen is the ratio of the Width to the Height of the screen.

We are told that the TV screen  has an aspect ratio of 21:9

Therefore:

\dfrac{Width}{Height}=\dfrac{21}{9} \\$Since Width =80''\\\dfrac{80}{Height}=\dfrac{21}{9}\\$Cross multiply\\Height*21=80*9\\Height =(80*9) \div 21\\$Height =34.29

The height of the TV will be approximately 34.29 Inch.
