Part A:
14/40=x/840
14*840=40x
11760=40x
294=x
x=294
194 are expected to eat the tomato soup
Part B:
find the average of 10,11, and 14
35/3=11.67
11.67/40=x/840
40x=11.67*840
9802.8=40x
x=245.07
245.07/840
0.29175*100 = 29.175
29.175%
Answer:

Step-by-step explanation:
#Using the method of substitution and replacement of unknown values.
Given that

Express eqtn (ii) in terms of x

Replacing for x in eqtn (i)

Substitute y value in eqtn(ii) to obtain x

All triangles have angles that add up to 180, so we can take the top triangle, which has angles 14, 45, and x, and say they add up to 180, so 180-14-45=x and x = 121. For E, all angles that look like that and have opposite angles, then these opposites are equal, so both sides of E are 121. then we use the bottom triangle to solve for D with the fact that all triangles' angles add to 180 again. 180-27-121 = D, so D=32
The question is to find to rule
9 +9 =18
18+9=27
27+9=36
36+9=45
