x = the weight of one steel ball y = the weight of one brass ball 2x + 5y = 13 (2 + 2)x + (5 - 2)y = 12 by solving the above system of equations we find:

x = 1.5 lbs y =2 lbs one steel ball weighs 1.5 lbs.one brass ball weighs 2 lbs.

16) y varies directly as x is the same thing as y=mx where m is the constant
for the first equation where the length is 7 and weight is 49 there fore
7=m49 in which m=1/7 so to find the length of the 2nd equation
y=m63
y=1/7 x63
y=9 inches


17)The raiser with the $6.25 would raise more money because if 25 ticket is sold and money received is $125 then each ticket is sold for $5  which means if the ticket is sold for $6.25 then 25 would bring in $156.25

(a)It takes 51
never [62]

a) Given :

51 pounds of seed  can be planted in = 9 acre field.

Per pound of seed = \frac{9 \ acre}{51 \ pounds \ of \ seed}

We can convert 9/51 in simplest fraction by dividing top and bottom by 3.

We get

\frac{9/3}{51/3}=\frac{3}{17}

<h3>Therefore, 3/17 of an acrs can be planted per pound of seed.</h3>

b) $10 amount = 16 pounds of sugar.

$1 amount = 16/10 = 1.6 pounds of sugar.

<h3>Therefore, 1.6 pounds of sugar she got per dollar.</h3>
