Ksenya-84 [330]

Answer:

$\boxed{y = 3}$

Step-by-step explanation:

$= > \frac{5 - 7y}{2 + 4y} = - \frac{8}{7} \\ \\ = > 7(5 - 7y) = - 8(2 + 4y) \\ \\ = > (7 \times 5) - (7 \times 7y) = ( - 8 \times 2) + ( - 8 \times 4y) \\ \\ = > 35 - 49y = - 16 - 32y \\ \\ = > 35 - 49y + 32y = - 16 \\ \\ = > 35 - 17y = - 16 \\ \\ = - 17y = - 16 - 35 \\ \\ = > \cancel{- }17y = \cancel{- } 51 \\ \\ = > 17y = 51 \\ \\ = > y = \frac{51}{17} \\ \\ = > y = 3$

Joanne buys a rectangular rug with an area of 35/4 square meters. The length of the rug is 7/2 meters. What is the width, in met

Oxana [17]

Area = 35/4 m²

Length = 7/2 m

Area = length * width

35/4 = 7/2 * width

7/2 * width = 35/4

width = 35/4 ÷ 7/2

width = 35/4 × 2/7 = 5/2

Width = 5/2 m
