**Answer:**

Down Below

**Step-by-step explanation:**

b=0.5

g=0.8

1. 3b + 5g = ?

3×0.5+5×0.8=?

1.5+4= 5.5 cm

2. 6(3b+5g) = ?

18b + 30g

18×0.5+30×0.8

9+24= 33 cm

3. 2b + 3g

2×0.5+3×0.8

1+2.4=3.4 cm

4. 7(2b+3g)

14b + 21g

14×0.5+21×0.8

7+16.8= 23.8 cm

5. Add number 2 and 4 together

14b+21g+18b+30g= 32b+ 51g

Take numbers and add them from problems 2 and 4

23.8+33=56.8 cm

The answer to that question is

**<u>47/50 </u>**

255ft/4in = xft/1in

255(1) = 4(x)

255 = 4x

255/4 = 4x/4

63.75 = x

The scale is 63.75 or 1 inch = 63.75 feet
