Answer:

  3 < x < 6

Step-by-step explanation:

Use the perimeter formula to write an expression for the perimeter. Then put that in an inequality with the given limits. Solve for x.

  P = 2(L +W)

  P = 2((4x) +(2x +1)) = 2(6x +1) = 12x +2 . . . . . fill in the given values; simplify

The perimeter wants to be between 38 and 74 cm, so we have ...

  38 < 12x +2 < 74

  36 < 12x < 72 . . . . . subtract 2

  3 < x < 6 . . . . . . . . . divide by 6

_____

Additional comment

Solving a compound inequality is very much like solving a single inequality. You need to "undo" what is done to the variable. The rules of equality (ordering) still apply. If you were to multiply or divide by a negative number, the direction (sense) of the inequality symbols would reverse in the same way they do for a single inequality.

Here, our first step was to subtract 2 from all parts of the inequality:

  38 -2 < 12x +2 -2 < 74 -2   ⇒   36 < 12x < 72

The division by 12 worked the same way: all parts are divided by 12.

  36/12 < (12x)/12 < 72/12   ⇒   3 < x < 6

__

If it makes you more comfortable, you can treat the perimeter limits as two separate inequalities: 38 < 12x+2 and 12x+2 < 74. Both restrictions apply, so the solution set is the intersection of the solution sets of these separate inequalities.

Step-by-step explanation:

These are the angles

The measures of angles q, r, and s are q = 100°, r = 135°, and s = 125°.

What are Alternate Interior Angles?

Alternate Interior Angles are defined as the pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles. These angles are always equal.

These are the angles

⇒ q = 180 - 80  = 100

⇒ r = 180 - 45= 135

⇒ s = 180 - (180 - 80 - 45) = 125

So the sum of the measures of angles q, r, and s

⇒ q + r + s = 100 + 135 + 125 = 360°

Thus, the measures of angles q, r, and s are q = 100°, r = 135°, and s = 125°.

Lori brought sunglasses and flip-flops at a half-off sale.If she spent a total of $21 on the two items, what was the original price of the sunglasses?

Answers

The sunglasses were originally priced at $ 21.

Given that Lori brought sunglasses and flip-flops at a half-off sale, to determine, if she spent a total of $ 21 on the two items, what was the original price of the sunglasses (taking into account that they both cost the same) will be you must perform the following calculation:

50 = 21 100 = X 100 x 21/50 = X 2100/50 = X 42 = X

Thus, the total price of both goods is $ 42, which, divided in half, results in $ 21 (42/2).

Therefore, the sunglasses were originally priced at $ 21.

Answers

The monthly payment for the patio furniture will be $66.23

Cost of the patio furniture = $935

Since there's a 15% down payment, then the amount that the buyer will pay will be:

= 15% × $935

= 0.15 × $935

= $140.25

Therefore, the amount that is left to pay will be:

= $935 - $140.25

= $794.75

Since the balance will be paid for 12 months, the monthly payment will be:

= $794.75 / 12

= $66.23
