Option E:
The value of m that makes the inequality true is 5.
Solution:
Given inequality is 3m + 10 < 30.
Let us first simplify the expression.
3m + 10 < 30
Subtract 10 from both side of the equation.
3m < 20 – – – – (1)
<u>To find the value of m that makes the inequality true:</u>
Option A: 20
Substitute m = 20 in (1),
⇒ 3(20) < 20
⇒ 60 < 20
It is not true because 60 is greater than 20.
Option B: 30
Substitute m = 30 in (1),
⇒ 3(30) < 20
⇒ 90 < 20
It is not true because 90 is greater than 20.
Option C: 8
Substitute m = 8 in (1),
⇒ 3(8) < 20
⇒ 24 < 20
It is not true because 24 is greater than 20.
Option D: 10
Substitute m = 10 in (1),
⇒ 3(30) < 20
⇒ 90 < 20
It is not true because 90 is greater than 20.
Option E: 5
Substitute m = 5 in (1),
⇒ 3(5) < 20
⇒ 15 < 20
It is true because 15 is less than 20.
Hence the value of m that makes the inequality true is 5.
Option E is the correct answer.
Answer:
3,474.4
Step-by-step explanation:
4,250-25%=3187.5
3187.5+9%=3474.4
Answer: 210 percent increase
Step-by-step explanation: So w know the starting value is k so we can replace it with 1 dollar
now we know he bought the dresser for 1 dollar and sold it for 3.10 dollars
First we have to subtract the starting value 3.1 - the original value
3.1 - 1 = 2.1
then we have to divide that number by the starting value
2.1 divided by 1 = 2.1
Lastly multiply times 100 to get the percent increase
2.1 x 100 = 210 % increase
