Answer:

j = $7

b = $12

c = $15

Step-by-step explanation:

Let

j = cost of one pound of jelly

b = cost of one pound of Bonbon

c = cost of one pound of chocolate

First week:

two pounds of Jellies and two pounds of Bonbons for $38.

2j + 2b = 38

Second week:

two pounds of Jellies and four pounds of Chocolates for $74

2j + 4c = 74

Third week:

two pounds of Jellies, two pounds of Bonbons and one pound of Chocolates for $53.

2j + 2b + c = 53

Recall,

2j + 2b = 38

So,

38 + c = 53

c = 53 - 38

= 15

c = $15

Substitute c = 15 into

2j + 4c = 74

2j + 4(15) = 74

2j + 60 = 74

2j = 74 - 60

2j = 14

j = 14/2

= 7

j = $7

Substitute j = 7 into

2j + 2b = 38

2(7) + 2b = 38

14 + 2b = 38

2b = 38 - 14

2b = 24

b = 24/2

= 12

b = $12

Answer:

C:) 17/3

Step-by-step explanation:

Simplify the following:

((3 + 2/5)×5)/3

((3 + 2/5)×5)/3 = ((3 + 2/5)×5)/3:

((3 + 2/5)×5)/3

Put 3 + 2/5 over the common denominator 5. 3 + 2/5 = (5×3)/5 + 2/5:

((5×3)/5 + 2/5 5)/3

5×3 = 15:

((15/5 + 2/5)×5)/3

15/5 + 2/5 = (15 + 2)/5:

((15 + 2)/5×5)/3

15 + 2 = 17:

(17/5×5)/3

17/5×5 = (17×5)/5:

((17×5)/5)/3

((17×5)/5)/3 = (17×5)/(5×3):

(17×5)/(5×3)

(17×5)/(5×3) = 5/5×17/3 = 17/3:

Find the value of a.B.find the value of the marked angles
Bond [772]

Answer:

a. 18 b. 119°, 118°

Step-by-step explanation:

a. Given angles are vertical, so they are equal.

6a+11 = 2a+83

6a-2a = 83-11

4a = 72

a = 72/4

a = 18

b. Substituting the value of a in the given angles,

6a+11 = 6*18+11 = 108+11 = 119°

2a+83 = 2*18+83 = 36+83 = 118°

How do you solve (x3 + 6x2 + 3x + 1 ) ÷ (x - 2)
WINSTONCH [101]
We conduct long division, cancelling each term in x³ + 6x² + 3x + 1. As so:

x²(x -2) = x³ - 2x²
Subtracting from the original equation, we get:
8x² + 3x + 1

8x(x - 2) = 8x² - 16x
Subtracting from the new equation, we get:
21x + 1

21(x - 2) = 21x - 42
Subtracting from the new equation, we get:
43

The answer is x² + 8x + 21 with a remainder of 43.
