-7.2x + 8.7x = -3.5 - 10
1.5x = -13.5
x = -13.5/1.5
x = -9
Answer:
E
Step-by-step explanation:
We were told Steven spent an amount of 50,000. Although the value of the dollar against the yen has changed. So therefore, to calculate the amount of money he spent, we would be needing to divide the amount he spent over the present exchange rate of the dollars to yen.
We then divide the 50,000 by 100 and that equals $500.
Hence, the amount of money spent by Steven is simply $500
Answer:
y=-7
Step-by-step explanation:
y-y1=m(x-x1)
y-(-7)=0(x-5)
y+7=0
y=0-7=-7
Answer:
12300 militers
Step-by-step explanation:
1 milileter = .001 liter
12.3 liters = 100 x 12.3
Since he sells 5 large cards for every 2 small, we can multiply the number of small cards he needs to sell by 2.5 to find how many large cards he needs to sell.
So let x=the number of small cards sold, and 2.5x=the number of large cards sold
The equation is:Total profit=x+(2.5x)
Since a small card is $2.5, a large card is $4, and the total profit will be $10,000 plug those in to make the equation:
10,000=2.5x+4(2.5x)
We can combine the x's to get 10,000=12.5x and then divide both sides by 12.5 to get x=800.
So he needs to sell 800 small cards.
Multiply that by that 2.5.
And he needs to sell 2000 large cards.
