The length of a rectangle is 8 cm more than it’s width. The perimeter is 68 cm. Find the length and the width of the rectangle.

1 answer:

4 0

To solve this we need to form an equation, using L for length and W for width

Perimeter=2L+2W
68=2L+2W

Because the length is 8cm more than the width we can say it is W+8.

68=2(W+8)+2W
68=2W+16+2W
68=4W+16
52=4W
W=13cm
L=(13+8)=21cm

Find the value of x in the triangle shown below.<br> 56°<br> 4<br> 4.5<br> 4

svetlana [45]

Step-by-step explanation:

$\frac{ \sin(56) }{4} = \frac{ \sin(x) }{4.5} \\ \sin(x ) = \frac{4.5 \times \sin(56) }{4} = \frac{3.73}{4} \\ \sin(x) = 0.9326 \\ x = 68.84$

Lexi made 14 sandwiches for a group picnic. The number of ham sandwiches she made was 4 less than the twice the number of turkey

shutvik [7]

x = # of ham sandwiches

14-x = # of turkey sandwiches ( as Lexi made 14 sandwiches)

as the question said that the number of ha sandwiches are 4 less than twice number of turkey sandwiches,

x = 2 * (14-x) - 4 = 24 - 2x

3x=24

x = 8

the number of ham sandwiches is 8, and the number of turkey sandwiches is 14-8=6
