Mathematics

erastova [34]2 years ago
5 0

-4 < 4(6y - 12) - 2y

<em><u>Distributive property.</u></em>

-4 < 24y - 48 - 2y

<em><u>Combine like terms.</u></em>

-4 < 22y - 48

<em><u>Add 48 to both sides.</u></em>

44 < 22y

<em><u>Divide both sides by 22.</u></em>

2 < y

The value of y is greater than the value of 2.

Melanie swarm for 142 minutes during her first week of vacation. In her two weeks of vacation she swam for a total of 347 minute
Soloha48 [4]

Answer: Melanie swam 63 minutes more in second week.

Step-by-step explanation:

Given ,  Time taken by Melanie in first week to swim = 142 minutes

Combined  time taken by her in first two weeks in swimming = 347 minutes

Now , time taken by her in second week =  (Combined  time  of first two week) - (Time taken in first week)

= 347-142 minutes

=  205 minutes

Clearly , 205 > 142 i.e. She swam more in second week than first week./

Difference i= 205-142 = 63

Therefore, Melanie swam 63 minutes more in second week.

erica [24]

Answer:

\huge\boxed{\sf 3(n + 5) \leq  100}

Step-by-step explanation:

  • The sum of a number n and 5 => n + 5
  • Thrice the sum of a number n and 5 => 3(n + 5)
  • At most means "less than or equal to", the sign of which is "≤"

<u>So, the inequality will be:</u>

3(n + 5) ≤ 100

\rule[225]{225}{2}

Hope this helped!
