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

Salma and Jared each threw 5 darts at the target shown. Salma scored 19 points by landing 2 darts in A and 3 in B. Jared scored
victus00 [196]

Answer:

5

Step-by-step explanation:

this can be solved using simultaneous equation

2a + 3b = 19  equation 1

1a + 4b = 17    equation 2

Multiply equation 2 by 2

2a + 8b = 34  equation 3

Subtract equation 1 from 3

5b = 15

b = 3

Substitute for b in equation 1

2a + 3(3) = 19

2a = 9 = 19

2a = 10

a = 5
