I only know D. but I'll try to figure out the rest too. D. 9 years old
130 + 110 = 240 degree celcius difference between high and low temperature
(2/3)(30)=20
30+20=50=(x/5)
(50*5)=x=250
hope this helps
Convert 9/5 and -4/5 to decimal form
= 1.8 and -0.8
so answer is -2.5 , -1.1 . -0.8, 0.8, 1.8
= -2.5, -1.1 , -4/5, 0.8, 9/5
