7x+5y=-24 (1)
4x+y=42 (2)
multiply equation (2) by 5 to get
20x+5y=210 (3)
then calculate (3)-(2) which gives you
13x=234 hence x=18
then substitute for x in either equation to get y=-30
Answer:
42.86%.
Step-by-step explanation:
Reduction in price = $70.00 - $40.00 = $30.00
Reduction in percentage = ($30.00 ÷ $70.00) x 100 = 42.86%
The price of the videogame was reduced by 42.86%.
Answer:
The answer will be 85,968
B. To be careful, use brackets: 10(1*2) + 4x which will be 20 + 40x or as you have it, 10*2 + 40x.
