The length of a rectangle is 3 feet more than the width. If the perimeter is 82 feet, what are the length
Tems11 [23]

Answer:

L=22feet

w=19feet

Step-by-step explanation:

Perimeter(p)=82

Length=(L)

Width=(w)

P=2L+2w

2L+2w=82 .......(1)

L-w=3........(11)

From (11) L=3+w

Substitute L=3+w in (1)

2(3+w)+2w=82

Clearing brackets

6+2w+2w=82

6+4w=82

Collect like terms

4w=82-6

4w=76

w=76/4

w=19

Substitute w=19 in (11)

L-19=3

Collect like terms

L=3+19

L=22

7 3/9 - 2 4/9 =<br>11 3/4 - 5 1/4 =​
jeka57 [31]

1.)

7 \frac{3}{9}  - 2 \frac{4}{9}  \\  =  \frac{66}{9}  -  \frac{22}{9}  \\  =  \frac{44}{9}  \\  = 4 \frac{8}{9}

2.)

11 \frac{3}{4}  - 5 \frac{1}{4}  \\  =  \frac{47}{4}  -  \frac{21}{4}  \\  =  \frac{26}{4}  \\  =  \frac{13}{2}  \\  = 6 \frac{1}{2}

Help me pls thank you
Tanzania [10]

Answer:

discrete

Step-by-step explanation:

This graph is discrete. A discrete graph has separate values, which are represented by multiple unconnected points. In continuous graphs, the values are all connected to each other. If this graph was continuous, then we would see a line rather than separate dots. The graph can also not be neither continuous nor discreet because it passes the vertical line test, meaning that it is a function.

Hope this helps :)
