Determine the smallest integer value of x in the solution of the following inequality.4x – 1 > 18

Answers

Answer:

x = 5

Step-by-step explanation:

You need to find de value of x.

4x - 1 = 18

4x = 18 + 1

4x = 19

x = 19/4

x = 4,75 but, the questions says: smallest integer value, so, the smallest is the integer number more near of 4,75, which is 5.

testing:

x = 5

4*5 - 1 > 18

20 -1 > 18

19 > 18 TRUE

x = 4

4*4 - 1 > 18

16 - 1 > 18

15 > 18 FALSE

Reflectional symmetry is the qualitya design has if it maintains all characteristics when it is rotated about:

A. an edge lying in its plane.
B. an axis lying in its plane.
C. a point lying in its plane.
D. an axis lying in its opposite plane.

Answers

The right answer for the question that is being asked and shown above is that: "D. an axis lying in its opposite plane." Reflectional symmetry is the quality a design has if it maintains all characteristics when it is rotated about D. an axis lying in its opposite plane.

Answer: c - a point lying on its plane

The perimeter of a rectangle is 38 inches. If the length of the rectangle is 14 inches, which equation could be used to find the width, x?

Answers

Perimeter, P = 2*(L + W)

Length, L = 14, Width = x

P = 2*(L + W)

38 = 2*(14 + x).

2*(14 + x) = 38, is the equation used to find x.

Let's go ahead and solve for x, though the question did not ask us to solve it.

14 + x = 38/2

14 + x = 19

x = 19 - 14

x = 5

Width is 5 inches.

Answer: x = 19 - 14

so 5 inch

Caleb had to share 3 1/4 boxes of supplies with his 12 classmates. What fraction of a box does each student receive?

Answers

Caleb had to share 3 1/4 boxes of supplies with his 12 classmates. So, the fraction of each student receives 13/48 of a box of supplies.

To find out what fraction of a box each student receives, we need to divide the total number of boxes (3 1/4 boxes) by the number of students (12 classmates).

Step 1: Convert 3 1/4 to an improper fraction.

3 1/4 = (4 × 3 + 1) / 4 = 13/4

Step 2: Divide the total number of boxes by the number of students.

Fraction of a box per student = (Total boxes) / (Number of students)

Fraction of a box per student = 13/4 ÷ 12

Step 3: To divide a fraction by a whole number, we multiply the fraction by the reciprocal of the whole number (flipping the fraction).

Fraction of a box per student = 13/4 × 1/12

Step 4: Simplify the fraction if possible.

Fraction of a box per student = 13/4 × 1/12 = 13/48

So, each student receives 13/48 of a box of supplies.
