Answer:
37 %
Step-by-step explanation:
Dylan's initial credit balance = $600.00
Credit balance after expenses= $378.00
Amount spent on purchases : $600 - $378
= $222.00.
To calculate for percentage decrease:
(Decrease / Total initial balance) * 100
%age Decrease = (222/600) * 100
= 222/6
= 111 / 3
= 37 %
It therefore means that, Dylan spent 37% of his total $600.00 to have a remaining credit balance of $378.00
Equations b and d have the same solutions, because if you multiply both sides of b by 2 and invert the constants you'll have equation d:
b: x - 3 = 5x + 4
b*2: 2x - 6 = 10x + 8
Move -6 and +8 to the other side: 2x -8 = 10x +6 <-- this is equation d
Similarly, starting from equation a, you can obtain equation e by multiplying both sides by 2 and equation f by dividing both sides by 10.
Equation c has nothing in common with the others.
Hi there!

Answer:
5 pounds of shrimp and 5 pounds of crawfish were purchased in the mixture.
Step-by-step explanation:
We are given the following in the question:
Bobby buys 10 pounds seafood for $30.
Let x pounds of shrimp be purchased and y pounds of crawfish.
Thus, we can write,
Cost of shrimp = $5 per pound
Cost of crawfish = $1 per pound
Total money spent = $30
Thus, we can write the equation,
Solving the two equation by elimination method,
Thus, 5 pounds of shrimp and 5 pounds of crawfish were purchased in the mixture.
