A rectangular field is four times as long as it is wide. If the perimeter of the field is 520 yards, what are the field's dimens

juin [17]

Answer:

Width = 52 yards

Length = 208 yards

Step-by-step explanation:

(2 * 4x) + 2x = 10x

10x = 520

x = 52

52 * 4 = 208

(208 * 2) + (52 * 2) = 416 + 104 = 520 yards

Carmen rides her bicycle at a constant rate to the market. When she rides her bicycle back home along the same route, she bikes

prisoha [69]

We will use the equation:
r t = 3/4 r ( t+12 ) /:r
t = 3/4 t + 9
t - 3/4 t = 9
1/4 t = 9
t = 9 * 4 = 36 minutes ( takes a trip to the market )
36 + 12 = 48 minutes
The ride home takes 48 minutes.

What is the length of AB

Naya [18.7K]

The 2 triangles are similar so corresponding sides are in the same ratio

4/5 = 6 +x / 4x- 8
cross multiply;
30 + 5x = 16x - 32
11x = 62x
x = 5.636

AB = 4(5.636) - 8 = 14.545

Answer:

$A.\,\orange{ \bold{ \frac{x - 3}{3x + 1} }}$

Step-by-step explanation:

$\frac{x + 2}{ {x}^{2} + 5x + 6 } \div \frac{3x + 1}{ {x}^{2} - 9} \\ \\ = \frac{x + 2}{ {x}^{2} + 3x + 2x+ 6 } \div \frac{3x + 1}{ {x}^{2} - {(3)}^{2} } \\ \\ = \frac{\cancel{x + 2}}{ \cancel{{({x}+ 3)}} \cancel{(x+ 2) }} \times \frac{\cancel{( {x} + 3)}( {x} - {3)}}{3x + 1} \\ \\ = \purple{ \bold{ \frac{x - 3}{3x + 1} }}$
