{-2x-5y=13
<u>{2x-5y=17 </u>(+)
<em /> -2x+2x-5y-5y=13+17
-10y=30 /:(-10)
y=-3
2x-5y=17
2x-5*(-3)=17
2x+15=17
2x=2
x=1
<em>Solution: (1; -3)</em>
Hi there!
The term "difference" os the result of subtracting one number from another.
So in other terms you want to know what would be the result of subtracting -4.6 from 13.5 :
13.5 - -4.6 = Difference between the two temperatures
Two minus signs turn into a positive sign so :
13.5 - -4.6 =
13.5 + 4.6 =
18.1 = Difference between the two temperatures
Your answer is : The difference between the two temperatures is 18.1
There you go! I really hope this helped, if there's anything just let me know! :)
Answer:
<h3>The volume is 144.</h3>
Step-by-step explanation:
Volume of a rectangular solid = l × w × h
where
l is the length
w is the width
h is the height
From the question
l = 12 feet
w = 3 feet
h = 4 feet
Volume = 12 × 3 × 4
= 144 feet
Hope this helps you.
