Sophia bought 3 yards of trim to put around a rectangular scarf. She wants the width of the scarf to be a whole number that is at least 6 inches and at most 12 inches. If she uses all the trim,wh Write your answers in inchesat are the possible dimensions of her scarf?

Answers

Answer:

The length of the scarf is at least 42 inches and at most 48 inches.

Step-by-step explanation:

We are given the following information:

Length of trim = 3 yards = 108 inches

The width of the scarf to be a whole number that is at least 6 inches and at most 12 inches.

Let w be the width of the scarf and l be the length of scarf.

Perimeter of scarf =

$\text{Permiter of rectangle} = 2(l+w)$

Then, we can write:

$6 \leq w \leq 12\n6+l \leq w+l \leq 12+l\n2(6+l) \leq 2(l+w) \leq 2(12+l)\n2(6+l) \leq \text{Perimeter of scarf}) \leq 2(12+l)\n2(6+l) \leq 108 \leq 2(12+l)\n\Rightarrow 2(6+l) \leq 108\n12 + 2l \leq 108\nl \leq 48\n\rightarrow 108 \leq 2(12+l)\n108 \leq 24 + 2l\nl \geq 42\n\Rightarrow 42 \leq l \leq 48$

The length of the scarf is at least 42 inches and at most 48 inches.

possible dimensions of the scarf are:
Width:6 inches Length:96inches
Width:12 inches Length:84 inches
Width:11inches Length: 86 inches
Width:10 inches Length: 88 inches
Width: 7 inches Length: 94 inches
Width: 8 inches Length: 92 inches
Width: 9 inches Length: 90 inches

I NEED HELP PLZZZ Josh simplified 4x - 8x / 2 and said the answer was -2x. What was Josh's error? What should his answer have been?\

Answers

Hello there,

This is a trick question Josh did not have an error. If you have 4x-8x in the numerator that becomes a -4x/2.
So then -4x/2= -2x
Josh was not wrong.

I hope this helped!
