Answer:
15
Step-by-step explanation:
since both equations are set with a right angle, the equation must be equal to 90 degrees. So you set the equation as
13+x+4x+2=90
add the x variables together and the constants separately
15+5x=90
then subtract 15 from both sides.
15+5x=90
-15 -15
5x=75
then divide 5 from both sides.
75/5= 15
so x is 15 :).

Answer: Our required interval for temperature is 
Step-by-step explanation:
Since we have given that
The normal temperature range for Yuma, on Janurary is atleast = 48 degrees
and the highest temperature on that day is no higher than 64 degrees.
Let the temperature in Yuma be 'x'.
So, we know that for atleast means it can 48 degrees or more, and no higher than means it should be equa to or less than 64 degrees.
Mathematically, it is expressed as

Hence, our required interval for temperature is
