Delia has 3 5/8 yards of ribbon. About how many 1/4 yard-long pieces can she cut?

Maurinko [17]

Answer

$Find\ out\ how\ many\ \frac{1}{4}\ yard-long\ pieces\ can\ delia\ cut .$

To prove

$Let\ us\ assume\ that\ the \ \frac{1}{4}\ yards\ pieces\ cut\ be\ x.$

As given

$Delia\ has\ 3\frac{5}{8}\ yards\ of\ ribbon.$

i.e

$Delia\ has\ \frac{29}{8}\ yards\ of\ ribbon.$

Than the equation becomes

$\frac{29}{8} = \frac{x}{4}$

$\frac{29\times 4}{8} = x$

$\frac{29}{2} = x$

x = 14.5

$Therefore\ the \ \frac{1}{4}\ yards\ pieces\delia\ cut\ be\ 14 .$

What is the answer? And how do I Solve, you get brainiest if you show steps clearly.

scoundrel [369]

Step-by-step explanation:

solution,

given

DF = 42

DE = 7x+1

EF = 4x-3

DE = ?

here,

or, DF = DE +EF

or, 42 = 7x+1+4x-3

or, 42 = 11x-2

or, 42+2 = 11x

or, 44/11 = x

or, 4 = x

then,

replacing value of x in DE

DE = 7x+1

= 7*4+1

= 28+1

= 29
