Answer:
962891995
Step-by-step explanation:
The package with the most low cost is 7.
N+d=47
5n+10d=295
divide 2nd by 5
n+2d=59
we have
n+d=47
n+2d=59
eliminate n
multiply first equaton by -1 and add to other equaton
-n-d=-47
<u>n+2d=59 +</u>
0n+1d=12
d=12
sub back
n+d=47
n+12=47
minus 12 both sides
n=35
35 nickles
D is answer
Weight of one large bead is 1.5 grams and weight of one small bead is 8.75 grams.
Step-by-step explanation:
Let,
Weight of one large bead = x
Weight of one small bead = y
According to given statement;
12x+8y=88 Eqn 1
5x+2y=25 Eqn 2
Multiplying Eqn 2 by 4

Subtracting Eqn 1 from Eqn 3

Dividing both sides by 8

Putting x=1.5 in Eqn 1

Dividing both sides by 8

Weight of one large bead is 1.5 grams and weight of one small bead is 8.75 grams.
