Answer 1

Answer:

1) 2

2) 5

3) 4

4) 4

5) 9

6) 12

Step-by-step explanation:

1)

3y + 6 = 12

3y = 12-6

3y = 6

y = 6/3

y = 2

2)

10+3v = 25

3v = 25-10

3v = 15

v = 15/3

v = 5

3)

2x+8 = 16

2x = 16-8

2x = 8

x = 8/2

x=4

4)

(k/2)+ 4 = 6

k/2 = 6-4

k/2 = 2

k = 2*2

k = 4

5)

3h-5 = 22

3h - 22+5

3h = 27

h = 27/3

h = 9

6)

(j/3)+5 = 9

j/3 = 9-5

j/3 = 4

j = 3*4

j = 12

The perimeter of rectangle QRST is the same as the perimeter of Rectangle LMNP. The length of Rectangle QRST is 2x + 9 meters. What is the width, in meters, of rectangle QRST?

Answers

Answer:

width of rectangle QRST= (5x-7)meters

Step-by-step explanation:

For LMNP rectangle,

Perimeter= 2(3x+5+4x-3)

=2(7x+2)

=14x+4

Now for QRST Rectangle,

perimeter of QRST rectangle= perimeter of LMNP rectangle (from question)

so,we have:

perimeter of QRST Rectangle= 14x+4

2(2x+9+w)= 14x+4 (let,w= width of rectangle QRST)

4x+18+2w=14x+4

2w=10x-14

w=(5x-7) m

Hence,the width of Rectangle QRST is (5x-7)m.
