The length of a rectangle is 24 units. Can the perimeter x of the rectangle be 60 units when its width y is 11 units? (1 point)
zlopas [31]
The first choice is correct. No, the rectangle cannot have x=60 and y=11 because x=48+2y.

Perimeter is x=2w+2y. Therefore x=2(24)+2(11) which equals 70 not 60.

Four times a number added to 3 times a larger number is 31. Seven subtracted from the larger number is equal to twice the smalle
Rus_ich [418]

Answer:

y = negative four-thirds x + StartFraction 31 Over 3 EndFraction

y = 2 x + 7

Step-by-step explanation:

Let x represent the smaller number and y represent the larger number.

<h2><u /></h2><h2><u>Part 1</u></h2>

Four times a number added to 3 times a larger number is 31.

<u>It is translated as:</u>

  • 4x + 3y = 31

<u>Then, solving for y:</u>

  • 4x + 3y=31 ⇒ 3y= -4x+31 ⇒ y= (-4x+31)/3 = - 4/3x + 31/3

    ⇒  y= - 4/3x + 31/3

<u>Correct answer choice for this equation:</u>

y = negative four-thirds x + StartFraction 31 Over 3 EndFraction

<h2><u>Part 2 </u></h2>

Seven subtracted from the larger number is equal to twice the smaller number.

<u>It is translated as:</u>

  • y-7= 2x

<u>Then, solving for y:</u>

  • y-7= 2x ⇒ y= 2x+ 7

<u>Correct answer choice for this equation:</u>

y = 2 x + 7
