A picture frame has a perimeter of 100 cm. Its width is 4 cm less than twice its length. What is the width of the picture

katrin [286]

Answer:

The correct answer is option 2: 32 cm

Step-by-step explanation:

Let l be the length of the picture frame and w be the width

Then according to given statements, the system of equations will be

$2l+2w = 100\ \ \ Eqn\ 1\\w = 2l-4\ \ \ Eqn\ 2$

Putting w = 2l-4 in equation 1

$2l+2(2l-4) = 100\\2l+4l-8=100\\6l-8 = 100\\6l = 100+8\\6l=108\\\frac{6l}{6}=\frac{108}{6}\\l = 18$

Putting the value of l in equation 2

$w = 2(18)-4\\w = 36-4\\w = 32$

The width is 32 cm

Hence,

The correct answer is option 2: 32 cm

Solve the simultaneous equation.......2x + 10y = 50 (equation 1) and 1.5x + 25y = 90 (equation 2)

cricket20 [7]

Step-by-step explanation:

2x + 10y = 50 ... 1

1.5x + 25y = 90 ...2

...1 × 2.5

5x + 25y = 125 ...3

...3 - ...2

3.5x = 35

x = 10

replaced x = 10 in ...1

2(10) + 10y = 50

20 + 10y = 50

10y = 50 - 20

10y = 30

y = 3
