it says use multiplication princple.
how do i solve it?

Answer 1

is it negative 105?

Answer 2

Answer 3

You create an inequality and solve.

-7x>(1/15)
divide by -7, and when you divide across an inequality with a negative, you must switch the direction of the sign, so
X<(1/15)(-1/7)
X<(-1/105)

So your answer is, x is less than -1/105.

Answer 4

So yes.

Answer 5

x<-1/105

Answer 6

so when i type it in should i type it as a fraction or i can just type < -105

Answer 7

fraction

Answer 8

Yeah it must be a fraction or the original expression is not true. If you substitute -105 in the first equation, it is not true. But if you substitute -1/105, it will be true, so it must be a the fraction.
