Answer:

Chair $280

Loveseat $560

Couch $ 1,160

Step-by-step explanation:

chair = x

loveseat=2x

couch = 2x + 600

x +2x + 2x +600 = 2000

5x + 600 =2000 subtract 600 from both sides

5x =1400 divide by 5

x = $280

Chair is the value of x =$280

Loveseat is twice the value of x = 2 x $280 =$560

Couch is twice the value of x plus $600 = $560 + $600

Point M is on line segment LN. Given LN = 9, MN = 4x, and LM=5x
andrew-mc [135]

Answer:

MN = 4

Step-by-step explanation:

Given that L, M, N are collinear,

LN = 9,

MN = 4x

LM = 5x

Required:

Length of MN

SOLUTION:

To calculate the numerical length of MN, we need to find the value of x.

To find the value of x, generate an equation to solve for x as follows:

LM + MN = LN (segment addition postulate)

5x + 4x = 9 (substitution)

Solve for x

9x = 9

Divide both sides by 9

\frac{9x}{9} = \frac{9}{9}

x = 1

MN = 4x

plug in the value of x

MN = 4(1) = 4

What is the least common denominator of 3/4 and 15/16
Rudiy27

The least common denominator of 3/4 and 15/16 is 16.

<h3>What is Least Common Denominator?</h3>
  • When two or more fractions are given, the least common denominator is the smallest number of all common multiples of the denominators.
  • To find the least common denominator, list the multiples of both denominators until you find the smallest multiple shared by both.
  • Because 28 is the first shared multiple of 4 and 7, it must be the least common denominator of these two fractions.

So, LCD od 3/4 and 15/16:

  • 3/4 × 4/4 = 12/16
  • 15/16 × 1/1 = 15/16

Now, the denominator of both the fractions is the same which is 16.

Therefore, the least common denominator of 3/4 and 15/16 is 16.
