Step-by-step explanation:
Let Kim's sister age be x.
Kim's age 2x
<u>According to the question</u> :
2x + x = 42
X = 14
Kim's age = 28 years
Kim's sister's age = 14 years
Answer:
=64.5
Step-by-step explanation:
6x .5x5x4.3=64.5
Answer: yes, it is a smaller temperature, which means that is "colder"
Step-by-step explanation:
I guess that the question is:
Is -10°F colder than - 4°C?
Ok, when we have a temperature T in Celcius, the equation to transform this quantity to the Fahrenheit scale is:
T' = (T*9/5) + 32°
Replacing T by the temperature in celcius, we get:
T' = (-4°*9/5) + 32° = 24.8°F
This means that -4°C is equivalent to 24.8°F
And -10°F is a smaller value than 24.8°F (which mean that is colder)
This implies that -10°F is colder than -4°C
Then the statement is true.
By rearranging x = 7y - 5 to make y the subject, we get
x + 5 = 7y ( By transposition method )
or, 
<h2>Answer:</h2>
Given:
AD is an angle bisector in triangle ABC. 
.
To find:
The value of 
.
Solution:
AD is an angle bisector in triangle ABC.
According to the angle sum property, the sum of all interior angles of a triangle is 180 degrees.
Using angle sum property in triangle CAD, we get
Therefore, the angle of angle ADC is 
.
