Answer:

21x + 35y

Step-by-step explanation:

When doing these expression problems, you have to DISTRIBUTE

When distributing, you multiply the 7 on the OUTSIDE of the parentheses to the 3x and if you know 7x3 is 21 so it becomes 21x

Now we do the same thing to the 5y, we multiply the 7 by the 5y to get 35y

Since we can’t combine the terms since they have different variables, our final answer is 21x + 35y

Hope this helps and please award brainliest!

You have $110 to spend at the mall. You want to buy at most 6 articles of clothing. A clothing store sells shirts for $12 and pa

gladu [14]

Answer:

Part a) The graph in the attached figure (see the explanation)

Pat b) see the explanation

Step-by-step explanation:

Part a) Write and graph a system of linear inequalities that represents this situation

Let

x ----> the number of shirts you can buy

y ----> the number of pants you can buy

we know that

The word "at most" is the same that " less than or equal to"

The word "at least" is the same that " greater than or equal to"

$x+y \leq 6$ ----> inequality A

The amount you have to spend minus the number of shirts multiplied by its price minus the number of pants multiplied by its price must be greater than or equal to $20

$110-12x-18y \geq 20$

Rewrite

$12x+18y\leq 90$ ----> inequality B

using a graphing tool

see the attached figure

Part b) How many shirts and pairs of pants can you buy at the store?

The solution of the system of inequalities is the shaded area

The solution is all whole numbers included in the shaded area

Example

(0,5),(3,3),(6,0), (3,2),...

the amount of stain needed to cover a wood surface is directly proportional to the area of the surface. If 3 pints are required

s2008m [1.1K]

For 10 feet and 6 inches,

12 inches = 1 foot, therefore 6 inches = 6/12 foot = 0.5 foot

10 feet 6 inches = 10 + 0.5 = 10.5 feet

7 feet required 3 pints

1 foot would have required (3/7) pints

10.5 feet will then require: (3/7)*10.5 = 4.5 pints.

Therefore 10 feet and 6 inches will require 4.5 pints.
