Answer:

They would weight 1\frac{1}{21} ounces

Step-by-step explanation:

Weight of complete package of paper = 3 \frac{4}{6} ounces

Weight of complete package of paper =\frac{22}{6}ounces

Edward put3\frac{1}{2} packages of paper on a scale

So, Weight of 3\frac{1}{2} packages   = \frac{\frac{22}{6}}{3\frac{1}{2}}

Weight of 3\frac{1}{2} packages = \frac{\frac{22}{6}}{\frac{7}{2}}

Weight of 3\frac{1}{2} packages =\frac{22}{21}=1\frac{1}{21}

Hence They would weight 1\frac{1}{21} ounces

Solve the following systems of equations 2a+4b+c=5 ; a-4b=-6 ; 2b+c=7.
SOVA2 [1]

Answer:

a = -2

b = 1

c = 5

Step-by-step explanation:

Given:

2a + 4b + c = 5 ............(1)

a - 4b = - 6

or

a = 4b - 6 .............(2)

2b + c = 7

or

c = 7 - 2b   ...........(3)

substituting 2 and 3 in  1, we get

2(4b - 6 ) + 4b + (7 - 2b) = 5

or

8b - 12 + 4b + 7 - 2b = 5

or

10b - 5 = 5

or

b = 1

substituting b in 2, we get

a = 4(1) - 6

or

a = -2

substituting b in 3, we get

c = 7 - 2(1)

or

c = 5

thus,

a = -2

b = 1

c = 5
