So b/10 has to be -1, that means b is -10
At the start pizza has -6
the temperature rises 13 during the transport, so it should have -6+13=7
because the temperature goes down 19 when pizza is put in the home freezer, the final temperature should be 7-19=-12
so b is the correct answer
if the temperature rises -> +
if the temperature goes down -> -
(12x +15)°=75° .…(शिर्षभिमुख कोण भएर)
or, 12x+15=75
or, 12x=75-15
or, 12x=60
or, x=60÷12
or, x=5
(6y-27)°=105° .…(शिर्षभिमुख कोण भएर)
or, 6y-27=105
or, 6y=105+27
or, 6y=132
or, y=132÷6
or, y=22
18, you do 63/3.5 to get how many for 1 minute
