Answer: Everybody will need to pay 3.18 dollars. ($3.18)
Step-by-step explanation:
To find out equal amounts of money, you need to divide the total cost by how many people there are. The total cost, in this case, is 12.72, and the amount of people in this problem is 4 people. That means, if everybody were to pay the same amount, you would need to divide 12.72 by 4.
12.72/4=3.18
Answer:
y = 5x - 7
slope = 5
Step-by-step explanation:
35x - 7y = 49
Subtract 35x from both sides.
-7y = -35x + 49
Divide both sides by -7.
y = 5x - 7
The equation is now in the slope-intercept form, y = mx + b, where m is the slope.
slope = m = 5
I need help my self lol XD sorryyyyyyyyy88898
Answer:
x is mL of 25% acid and y is mL of 50% acid
We set up 2 equations:
A) x + y = 250
B) .25 x + .50y = .35 * 250 which equals
B) .25x + .50y = 87.50 Multiplying A) by -.5
A) -.5x -.5y = -125 adding the equations we get
-.25x = -37.50
x = 150 mL
y = 100 mL
