To solve the inequality:
2(m - 3) + 7 < 21
First distribute 2 to both terms inside parentheses:
2m - 6 + 7 < 21
Combine like terms:
2m + 1 < 21
Subtract 1 from both sides:
2m + 1 - 1 < 21 - 1
2m < 20
Divide both sides by 2:
(2m)/2 < 20/2
m < 10
Thus, the solution to the inequality is m < 10.

Solve the inequality.
negative 2 left-parenthesis w plus 4 right-parenthesis plus 9 less than negative 11
negative 2 left-parenthesis w plus 4 right-parenthesis plus 9 less than negative 11
To solve the inequality:
-2(w + 4) + 9 < -11
First distribute -2 to both terms inside parentheses:
-2w - 8 + 9 < -11
Combine like terms:
-2w + 1 < -11
Subtract 1 from both sides:
-2w + 1 - 1 < -11 - 1
-2w < -12
Divide both sides by -2, remember to reverse the inequality when dividing by a negative number:
(-2w) / -2 > (-12) / -2
w > 6
Thus, the solution to the inequality is w > 6.
-2(w + 4) + 9 < -11
First distribute -2 to both terms inside parentheses:
-2w - 8 + 9 < -11
Combine like terms:
-2w + 1 < -11
Subtract 1 from both sides:
-2w + 1 - 1 < -11 - 1
-2w < -12
Divide both sides by -2, remember to reverse the inequality when dividing by a negative number:
(-2w) / -2 > (-12) / -2
w > 6
Thus, the solution to the inequality is w > 6.
The lengths of the sides of a triangle are in the ratio 5 colon 6 colon 7. Describe the length of the longest side if the perimeter is less than 54 cm.
Let's assume that the common ratio for the sides of the triangle is "x".
According to the given information, the lengths of the sides are 5x, 6x, and 7x.
The perimeter of the triangle is the sum of the lengths of all three sides:
Perimeter = 5x + 6x + 7x = 18x
We're given that the perimeter is less than 54 cm:
18x < 54
Divide both sides of the inequality by 18:
x < 3
Since x represents the common ratio, it needs to be a positive number. The largest positive integer less than 3 is 2.
So, x = 2.
Therefore, the lengths of the sides of the triangle are 5x = 5 * 2 = 10 cm, 6x = 6 * 2 = 12 cm, and 7x = 7 * 2 = 14 cm.
Among these lengths, the longest side is 14 cm.
According to the given information, the lengths of the sides are 5x, 6x, and 7x.
The perimeter of the triangle is the sum of the lengths of all three sides:
Perimeter = 5x + 6x + 7x = 18x
We're given that the perimeter is less than 54 cm:
18x < 54
Divide both sides of the inequality by 18:
x < 3
Since x represents the common ratio, it needs to be a positive number. The largest positive integer less than 3 is 2.
So, x = 2.
Therefore, the lengths of the sides of the triangle are 5x = 5 * 2 = 10 cm, 6x = 6 * 2 = 12 cm, and 7x = 7 * 2 = 14 cm.
Among these lengths, the longest side is 14 cm.
Find the lesser of two consecutive integers with a sum greater than 16.
Let's assume the two consecutive integers are x and x+1.
According to the given information, the sum of these integers is greater than 16:
x + (x+1) > 16
Combine like terms:
2x + 1 > 16
Subtract 1 from both sides:
2x > 15
Divide both sides by 2:
x > 7.5
Since we need to find the lesser of the two consecutive integers, we consider the integer value less than 7.5, which is 7.
Therefore, the lesser of the two consecutive integers with a sum greater than 16 is 7.
According to the given information, the sum of these integers is greater than 16:
x + (x+1) > 16
Combine like terms:
2x + 1 > 16
Subtract 1 from both sides:
2x > 15
Divide both sides by 2:
x > 7.5
Since we need to find the lesser of the two consecutive integers, we consider the integer value less than 7.5, which is 7.
Therefore, the lesser of the two consecutive integers with a sum greater than 16 is 7.
