Sagot :
Answer:
-16c
Step-by-step explanation:
Decrease means minus in this case
So:
-8c-8c=-16c
Answer:
On Friday: -8°c
On Saturday: Temperature decreases by 8°C
As 8°C is reduced again we need to subtract
⇒ -8 - 8
⇒ -16
We can understand this by counting or looking at a number line
in the number line when the values of a number decreases the number place moves to the left! So we need to move 8 places towards the left from -8 in the umber line
WHICH COULD BE SHOWIN LIKE THIS:
-17,-16,-15,-14,-13,-12,-11,-10, -9,-8,7,-6,-5,-4,-3,-2,-1,0,1,2,3.......
You try counting in the series of numbers i have given above start counting towards the left from -9 as 1 till u reach the 8th value which will be -16
Hope this helps.....
