Answer:
Step-by-step explanation:
The expression for the cost of the ABC Book Club is 2<em>x </em>+ 40. The expression for the cost of the Easy Book Club is 3<em>x</em> + 35. To find when the total charge for both book clubs is equal, the two expressions must equal each other. (<em>x </em>= the number of books read)
2<em>x </em>+ 40 = 3<em>x</em> + 35
Subtract 35 from both sides.
2<em>x </em>+ 5 = 3x
Subtract 2<em>x </em>from both sides.
5 = <em>x</em>
So, the total charge for each club is equal when 5 books are read.

3.14 x 10⁻³ has the value 0.00314
The exponent tells us the number of times the decimal has to move. The sign of the exponent tells us the direction of the movement of the decimal.
The negative sign of the exponent means that the decimal has to move to the right.
From 0.00314, decimal move to the right 0003.14
If the decimal is positive, it means that the decimal point moved to the left of the number.
3.14 x 10³ in expanded form is 3140
From 3140. decimal move to the left 3.140
