ANSWER

b = 5\frac{2}{3}

EXPLANATION

The given equation is

\frac{6}{b - 1} = \frac{9}{7}

where b≠1.

We cross multiply to get,

7 \times 6 = 9(b - 1)

Expand and multiply out to get,

42 = 9b - 9

Group similar terms,

42 + 9 = 9b

9b = 51

Divide both sides by 9

b = \frac{51}{9}

Simplify:

b = \frac{17}{3}

Or

b = 5\frac{2}{3}

Peggy had three times as many quarters as nickels. She had $1.60 in all. How many nickels and how many quarters did she have? Wh
svlad2 [7]
Let q and n represent the number of quarters and nickels respectively.

q=3n and .05n+.25q=1.6  These are the conditions in mathematical terms.

To solve, use the value of q from the first equation in the second equation to get:

.05n+.25(3n)=1.6  carry out indicated multiplication on left side

.05n+.75n=1.6  combine like terms on left side

.8n=1.6  divide both sides by .8

n=2, since q=3n

q=6

So Peggy had 2 nickels and 6 quarters.
