Step-by-step explanation:
just multiply each of the given numbers by three to find the answer (5 x 3)
Step-by-step explanation:
Let f(x) be number of yellow pencils and x be number of blue pencils.
We have been given that Shawna found out there are 4 yellow pencils for every blue pencil. We can represent this information in an equation as:
[tex]f(x)=4x[/tex]
Therefore, our desired equation will be: [tex]f(x)=4x[/tex].
Now let find number of yellow pencils for the given number of blue pencils by substituting the number of blue pencils in our equation as:
[tex]f(5)=4\cdot 5[/tex]
[tex]f(5)=20[/tex]
[tex]f(7)=4\cdot 7[/tex]
[tex]f(7)=28[/tex]
[tex]f(9)=4\cdot 9[/tex]
[tex]f(9)=36[/tex]
[tex]f(11)=4\cdot 11[/tex]
[tex]f(11)=44[/tex]
[tex]f(13)=4\cdot 13[/tex]
[tex]f(13)=52[/tex]
