Describe how to solve the inequality 3x+4<13 using algebra tiles
vladimir1956 [14]

The solution is x < 3.

Solution:

The given expression is 3x + 4 < 13.

To solve the given inequality.

3x + 4 < 13

Subtract 4 tiles on both sides of the inequality.

⇒ 3x + 4 – 4 < 13 – 4

⇒ 3x < 9

Divide by 3 tiles on both sides of the inequality.

⇒ \frac{3x}{3} =\frac{9}{3}

⇒ x < 3

Hence the solution is x < 3.

A store advertises 15% off an item that regularly sells for $300.
Ilia_Sergeevich [38]

Regular price = 300

Sale = 15%

Price after sale

= 300 - 15%(300)

= 300 - 15/100 x 300

= 300 - 15 x 3

= 300 - 45

= 255
