Answer:

AB = JK = 49

Step-by-step explanation:

Since ABC = JKL

We know the length of AB has to equal the length of JK.

AB = JK

14x+7 = 5x+34

Subtract 5x from each side.

14x-5x +7 = 5x-5x+34

9x+7 = 34

Subtract 7 from each side

9x+7-7 = 34 -7

9x = 27

Divide each side by 9.

9x/9 = 27/9

x =3

AB = 14x+7

Substitute x=3

14(3) +7

42+7

AB = 49

kirza4 [7]

QUESTION 1

When the plane reaches an altitude of 360,000 feet, the temperature outside the plane is 65 degrees below zero Fahrenheit.

This means that the temperature will be:

$0-65=-65$

The temperature is -65°F.

QUESTION 2

If the temperature gets warmer by 10 degrees, this means that the new temperature will be the sum of the original temperature and 10 degrees:

$\Rightarrow-65+10=-55$

The temperature is -55°F.
