Question

Which inequality represents the solutions to a over five + 3 < 5?

Answer 1

\[\frac{ a }{ 5 }+3 < 5\]
Reverse division of 5 by multiplication of 5;\[\frac{ a }{ 5 }+3\times5 < 5\times5\]
\[a+3<25\]
Subtract 3 from both sides;
\[a+3-3<25-3\]
\[a <22\]

Answer 2

a < 10

a > 10

a < 40

a > 40

Answer 3

I would think a < 40 because if a is < 22 and 22 is < 40 then a is < 40.

Answer 4

Which equation is solved by multiplying both sides by zero point two?

zero point two times z equals two

z plus zero point two equals two

z minus zero point two equals two

z divided by zero point two equals two
