Answer:
Equation:
[tex]6x=40[/tex] (See explanation)
Unknown factor:
[tex]x=\frac{20}{3}\\\\x\approx7[/tex]
Step-by-step explanation:
The complete exercise is: "What if Tanisha needs 40 bowls for the picnic? Explain how to write an equation with a letter for an unknown factor to find the number of packs she should buy. Then find the unknown factor."
The missing table is attached.
Let be "x" the number of packs that Tanisha should buy.
You know, based on the the table attached, that 1 pack has 6 bowls.
Therefore, you can say that the product obtained by multiplying "x" packs by 6 bowls must be 40 bowls.
Then, you can write the following equation. where the factors are 6 and "x" and 40 is the product:
[tex]6x=40[/tex]
In order find the unknown factor, you can divide both sides of the quation by 6. Then you get:
[tex]\frac{6x}{6}=\frac{40}{6}\\\\x=\frac{20}{3}\\\\x\approx7[/tex]
Therefore, she should buy 7 packs.
