First, simplify the existing terms. 
21 > 3a - 21 + 9
21 > 3a - 12
Then, add 12 to both sides
33 > 3a
Next, divide both sides by 3
11 > a
This gives you a < 11.

A retailer ordered a combination of 50 black and white sweatshirts. Each white sweatshirt cost him $10 and
Brut [27]

The number of white  sweatshirts is 28

Step-by-step explanation:

Let ordered black shirts be represented by b

Let ordered white shirts be represented by w

So total sweatshirts will be represented by the equation

b+w=50

The total cost of the ordered sweatshirts will be represented by

10b + 12 w= $556

For simultaneous equations as;

b+w=50

10b+12w=556

solving the equations using substitution method where b=50-w

10(50-w)+12w=556

500-10w+12w=556

-10w+12w=556-500

2w=56

w=56/2= 28

b=50-w=50-28=24

Number of white  sweatshirts  is 28

Anastasy [175]

Answer:

145 + 33n

Step-by-step explanation:

Let

n = number of members in the club

Day 1:

Cost = 50 + 18n

Day 2:

Cost = 95 + 15n

Total cost two-day field trip = day 1 + day 2

= (50 + 18n) + (95 + 15n)

= 50 + 18n + 95 + 15n

= 145 + 33n

Total cost two-day field trip = 145 + 33n

An expression that represents the total cost in dollars for two days for the n members of the club is given by 145 + 33n
