Drag the tiles to the boxes to form correct pairs. Match the pairs of equivalent expressions.

A. [tex]$\left(-14+\frac{3}{2} b\right)-\left(1+\frac{8}{2} b\right)$[/tex]

B. [tex]$4 b+\frac{13}{2}$[/tex]

C. [tex]$(5+2 b)+\left(2 b+\frac{3}{2}\right)$[/tex]

D. [tex]$8 b-15$[/tex]

E. [tex]$\left(\frac{7}{2} b-3\right)-(8+6 b)$[/tex]

F. [tex]$\frac{-5}{2} b-11$[/tex]

G. [tex]$(-10+b)+(7 b-5)$[/tex]

H. [tex]$-15-\frac{5}{2} b$[/tex]



Answer :

To match the pairs of equivalent expressions, follow these detailed steps to simplify each expression:

1. Simplify [tex]\(\left(-14 + \frac{3}{2} b\right) - \left(1 + \frac{8}{2} b\right) \)[/tex]:
[tex]\[ (-14) + \frac{3}{2} b - 1 - 4b = -14 - 1 + \frac{3}{2} b - 4b = -15 - \frac{5}{2} b \][/tex]

2. Simplify [tex]\(4b + \frac{13}{2}\)[/tex]:
[tex]\[ \text{This expression is already simplified.} \][/tex]

3. Simplify [tex]\((5 + 2b) + \left(2b + \frac{3}{2}\right)\)[/tex]:
[tex]\[ 5 + 2b + 2b + \frac{3}{2} = 4b + 5 + \frac{3}{2} = 4b + \frac{10}{2} + \frac{3}{2} = 4b + \frac{13}{2} \][/tex]

4. Simplify [tex]\(8b - 15\)[/tex]:
[tex]\[ \text{This expression is already simplified.} \][/tex]

5. Simplify [tex]\(\left(\frac{7}{2}b - 3\right) - (8 + 6b)\)[/tex]:
[tex]\[ \frac{7}{2}b - 3 - 8 - 6b = \frac{7}{2}b - 6b - 11 = \frac{7}{2}b - \frac{12}{2}b - 11 = \frac{-5}{2}b - 11 \][/tex]

6. Simplify [tex]\(\frac{-5}{2}b - 11\)[/tex]:
[tex]\[ \text{This expression is already simplified.} \][/tex]

7. Simplify [tex]\((-10 + b) + (7b - 5)\)[/tex]:
[tex]\[ -10 + b + 7b - 5 = 8b - 15 \][/tex]

8. Simplify [tex]\(-15 - \frac{5}{2}b\)[/tex]:
[tex]\[ \text{This expression is already simplified.} \][/tex]

Now, match the equivalent expressions:

- [tex]\(\left(-14 + \frac{3}{2} b\right) - \left(1 + \frac{8}{2} b\right) \equiv -15 - \frac{5}{2}b\)[/tex]
- [tex]\(4b + \frac{13}{2} \equiv (5 + 2b) + \left(2b + \frac{3}{2}\right)\)[/tex]
- [tex]\(\left(\frac{7}{2}b - 3\right) - (8 + 6b) \equiv \frac{-5}{2}b - 11\)[/tex]
- [tex]\((-10 + b) + (7b - 5) \equiv 8b - 15\)[/tex]

So, the pairs are:

1. [tex]\(\left(-14 + \frac{3}{2} b\right) - \left(1 + \frac{8}{2} b\right)\)[/tex] with [tex]\(-15 - \frac{5}{2} b\)[/tex]
2. [tex]\(4 b + \frac{13}{2}\)[/tex] with [tex]\((5 + 2 b) + \left(2 b + \frac{3}{2}\right)\)[/tex]
3. [tex]\(\left(\frac{7}{2} b - 3\right) - (8 + 6 b)\)[/tex] with [tex]\(\frac{-5}{2} b - 11\)[/tex]
4. [tex]\((-10 + b) + (7 b - 5)\)[/tex] with [tex]\(8 b - 15\)[/tex]
