The answer is C. 10p+6-p=12p-3(p-2)

because if you substitute any number for p, it will always equal each other

a. 5m-6=5m+7m

5(3)-6=5(3)+7(3)

15-6=15+21

9=36

b. 6(3)-5=7(3)+5-3

18-5=21+5-3

13=23

c. 10(3)+6-3=12(3)-3(3-2)

30+6-3=36-3

33=33

d. 3(3)+2=3(3)-2

9+2=9-2

11=7

Formulate the situation as a system of inequalities. (Let x represent the number of dinghies the company can manufacture and y r
kirill [66]

Answer:

x (smallest to largest) = 0,45 ,55

y (smallest to largest) = 0,10,40

Step-by-step explanation:

(hours)        Dinghy Rowboat        Labor Available

Metal Work 2             3                       120

Painting         2              2                        110

Let x represent the number of dinghies the company can manufacture and y represent the number of rowboats.

So, total hours for metal work = 2x+3y

So, total hours for Painting = 2x+2y

So, equation becomes:

2x+3y\leq 120

2x+2y\leq 110

x\geq 0

y\geq 0

Plot the inequalities

Refer the attached figure

So, the vertices of the feasible region are (0,40),(45,10) and (55,0)

So, x values are 0 , 45 and 55

x represents the number of dinghies

So, x (smallest to largest) = 0,45 ,55

y values are 40,10,0

y represent the number of rowboats.

So, y (smallest to largest) = 0,10,40
