Answer:

x=2

Step-by-step explanation:

4x + 3 = -5x + 21

  • add 5x on both sides
  • which will get u to 9x +3 = 21
  • subtract 3 from both sides
  • which will get u to 9x = 18
  • divide 9 from both sides
  • and the answer is x = 2

umka2103 [35]

The expressions that represent number of tiles that Devon used on her mosaic:

A. 20 + 2t + 2c

D. 20 + t + t + c + c

<h3>What is an expression?</h3>

An expression refers to a mathematical equation which shows the relationship between two or more numerical quantities or variables.

For the expressions that represent number of tiles that Devon used on her mosaic:

  • Let the triangle tiles be t.
  • Let the circle tiles be c.
  • Two rows of t triangle tiles = t + t = 2t.
  • Two rows of c circle tiles = c + c = 2t.

Mathematically, the expression is given by:

Total tiles = 20 + t + t + c + c

Total tiles = 20 + 2t + 2c.
