Please check attached vertical number line.
(a) The temperature differences are listed below:
Between Cities Temperature difference
Smithton and
Hedgeburough 2.5 - (-1.1) = 2.5 + 1.1 = 3.6
Hedgeburough and
East Bunting - 1.1 - (- 0.5) = - 1.1 + 0.5 = -0.6
East Bunting and
Smithton 2.5 - (- 0.5) = 2.5 + 0.5 = 3
-30= 5 (x+1 )
-5 from 5= 0
-5 from -30= -35
-35= (x+1)
1/-35= -35
Answer:
$144
Step-by-step explanation:
Let the money which Siti has be x
Therefore, the money June has will be x+240
First condition is that June gave 25% of her money to Siti, So this amount will be deducted from June's money and will be added in Siti's money.
Siti's money = x+ [25%(x+240)] June's money = x+240-[25%(x+240)]
= 1.25x + 60 = 0.75x + 180
Second condition is that Siti now gave 20% of her money to June.This amount will be deducted form Siti's money and added in June's money.
Siti's money = 1.25x+60-[20%(1.25x+60)]
= x+48
June's money = 0.75x +180+[20%(1.25x+60)]
= x+192
Difference between Sitit and June's money = x+192-x-48
= 144
Hence, June has $144 more money than Siti.
Answer:
Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time. Each of these equations on their own could have infinite possible solutions.
