For this case, the first thing you should do is define a variable.
We have then:
t: temperature (degree Fahrenheit).
We write then the inequation that adapts to the problem:
t> = 451
Answer:
an inequality that is true only for temperatures at which books spontaneously catch on fire is:
t> = 451
A(b-c)
First substitute values
-8(12+4)=
Next, solve using ordering of PEMDAS
-8 (12+4)=
-8 (16)=12
You minus 7 on both sides and you are left with y=2 because 7-9 = 2
The problem is saying that 17/20 times the number of dollars equals the number of euros converted. Which in this case to solve your problem, 17/20 times one equals 17/20.
