Answer 3

13 less than -31 is it suppose to be -31-13?

Answer 4

oh wait oops disregard what i just said

Answer 5

yes you would be right

Answer 6

That's the part I was confused.

Answer 7

40 less than twice 16

Is it suppose to be (16)^2 -16

Answer 8

i think it would mean 2*16

Answer 9

40 less than twice 16 is written \(40<2\cdot16\)

Answer 10

that would be true @helder_edwin if it said "is less than"

Answer 11

How is it 40< 2*16
don't I have to multiply 2*16? Wouldn't that be 32?

40>32?

Answer 12

right. sorry!!

Answer 13

i automatically put the "is"

Answer 14

Oh okay

Answer 15

Answer 16

i think "40 less than twice 16" would then be
\[ \large 2\cdot16-40 \]

Answer 17

okay
