These are the equations given:
31=B+J
B=2J+4

So you substitute B=2J+4 into 31=B+J

31=2J+4+J

Solve

31-4=3J+4-4
27=3J
27/3=3J/3
9=J

Jake has 9 cd's.

Answer:

j = 9 (# of CDs Jake has)

Step-by-step explanation:

Equations::

b + j = 31 CDs

b = 2j+4

-----

Substitute for "b" and solve for "j"::


2j+4 + j = 31

3j = 27

j = 9 (# of CDs Jake has)

ankoles [38]

Hello :D

To work this out you need to round the numbers to a whole number.

19.9 = 20

5.8 = 6

20 x 6 ≈ 120

I hope this helps :)

Please help lot of points at stake- and will give brainly.
Veronika [31]

Answer:

a)1400 + 300x ≤ 5000

b) x ≤ 12 days

Step-by-step explanation:

a) Since the grocery store owner wants to stay within budget then, this means he would be spending at most $5,000

The word at most is represented by the inequality sign ≤ = Less than or equal to

Let x = Number of days

Hence,

Our inequality equation is

$1400 + 300× x ≤ $5000

1400 + 300x ≤ 5000

b) Solving for x

1400 + 300x ≤ 5000

300x ≤ 5000 - 1400

300x ≤ 3600

x ≤ 3600/300

x ≤ 12 days
