Answer:

The combined length is 61 inches

Step-by-step explanation:

we know that

To find out the combined length of all the pieces Meg measured, multiply each measure by the number of pieces and then sum all the values

Let

x -----> the combined length

we know that

we have

1 piece of 3 inches

2 pieces of 5 inches

3 pieces of 6 inches

3 piece of 7 inches

1 piece of 9 inches

so

[tex]x=(1)(3)+ (2)(5)+(3)(6)+(3)(7)+(1)(9)\\x=3+10+18+21+9\\x=61\ in[/tex]

therefore

The combined length is 61 inches
