There are 12 white ribbons, 15 red ribbons, and 11 blue ribbons.

38=(w-1)+(w+3)+w
combine like terms
38=2+3w
subtract 2 from both sides
36=3w
divide 3 on both sides
12=w

w-1=b
12-1=b
11=b

w+3=r
12+3=r
15=r

Check Your Work
w+r+b=38
15+11+12=38
38=38

poizon [28]

Answer:

The quantity of ground meat he use for hamburgers is                                   2 \frac{13}{80} pounds

Step-by-step explanation:

Given as :

The total quantity of ground meat bought to make hamburgers = 2 \frac{9}{16}

Or, The total quantity of ground meat bought to make hamburgers = \frac{41}{16} pound

The quantity of ground meat left after use = \frac{2}{5} pound

Now, let The quantity of ground meat used for hamburgers = x pound

So, x = The total quantity of ground meat bought - The quantity of ground meat left

Or, x = \frac{41}{16} pound -  \frac{2}{5} pound

Or, x =  \frac{205-32}{80} pound

I.e x = \frac{173}{80}

∴  x = 2 \frac{13}{80} pounds

Hence The quantity of ground meat he use for hamburgers is                        2 \frac{13}{80} pounds  . Answer
