Answer: Part a) 375 pounds, Part b) 8 words

Step-by-step explanation:

<u />

Since n represents the number of words there are, we can plug in 20 for n into the equation to get:

C = 15*20 + 75 pounds

C = 300 + 75 pounds

C = 375 pounds

Since C represents the cost of the advert, we can plug in 195 for C into the equation to get:

195 = 15n + 75

Subtract 75 from both sides:

120 = 15n

Divide both sides by 15:

n = 8 words

svetlana [45]

Answer:

-5, 4.1, 4.7, 16 squared

Step-by-step explanation:

negative numbers are always the least, then 4.1 is less than 47/10 which is 4.7 and 16 squared which is 256, then we have 4.7 because that is less than 256 which is the greatest number.

You can spend at most $60 on beads. A bag containing red beads costs $2 per bag. A bag containing blue beads costs $3 per bag. Y

nexus9112 [7]

For this case, the first thing we must do is define variables.
We have then:
x: number of blue beads
y: number of red beads
We now write the inequations system:
$3x + 2y \leq 60

x\ \textgreater \ y$
Answer:
a system of linear inequations that represents the situation is:
$3x + 2y \leq 60 x\ \textgreater \ y$
