To answer this, you can set up a system of equations. Solve for one of the variables and substitute this new equation into the 2nd equation.
2x + 5y = 243 - I'll solve this one for x.
8x + 6y = 538
2x + 5y = 243
2x = 243 - 5y
2 2
x = 121.5 - 2.5y ; substitute this in for x in the second equation
8x + 6y = 538
8 (121.5 - 2.5y) + 6y = 538
972 - 20y + 6y = 538
972 - 14y = 538
-972 -972
-14y = -434
-14 -14
y = 31
<u><em>The cost of a rod (y) is $31. </em></u>
x = 121.5 - 2.5y
x = 121.5 - 2.5 x 31
x = 44
<em><u>The cost of a reel(x) is $44.</u></em>
Answer:
300 Burgers
Step-by-step explanation:
Since the question gives us an approximation of 250 burgers, we can round the number to 300. This is only because they had a estimation of 250 and would like to be prepared for the weekend. Being prepared would consist of ordering more than expected to make sure the burgers do not run out.
Plug values into distance formula, step by step shown in picture :)
Answer:
12 gold fish
Step-by-step explanation:
1) You have to subtract the total for fish food and 2 angel fish from the $15.00 that she spent.
$15.00-$3.00-$6.00 (2 fish at $3.00 each)=$6.00
2) You have to find out how many fish she could buy for $6.00 if the fish are $0.50 each.
$6.00 / 0.50 = 12 gold fish
