The difference between a number divided by 3 and 4 is 20.
Alexxandr [17]
Let, the number be "a"

Now, according to the question,
\frac{a}{3} - 4=20

\frac{a-12}{3} =20

a-12 =20*3

a-12=60

a = 60 + 12

a = 72


So, the number is 72

Answer:

8 + 1.5x + 0.75y = pizza_cost

Step-by-step explanation:

It is given that every 10-inch cheese pizza costs ($8), meaning that this will be the constant.

Let (x) represent the number of inches added to the pizza. Since each extra additional inch costs ($1.5) thus one adds (1.5x) to the equation.

Let (y) represent the number of toppings. Every extra topping costs ($0.75) therefore one has to add (0.75y) to the equation.

Putting all of the elements together one gets the equation,

8 + 1.5x + 0.75y

A grill at a barbecue restaurant will be used to cook sausage links that are 2 lb each and briskets that are 6 lb each. No more
horrorfan [7]

Answer:

2x + 6y ≤ 120

Step-by-step explanation:

From the above question, we are told that: No more than 120 lb of sausage links and briskets will be cooked on the grill.

Let

x = Number of sausage links

y = Number of Briskets

The word NO MORE THAN means less than or equal to 120 lb and this word is represented by the inequality sign:

≤

Sausage links = 2 lb each

Briskets = 6 lb each

The inequality =

2lb × x + 6lb × y ≤ 120lb

2x + 6y ≤ 120

Therefore, the inequality represents all possible combinations of x, the number of sausage links that will be cooked on the grill, and y, the number of briskets that will also be cooked is given as:

2x + 6y ≤ 120
