We have to set up 2 equations:
A) x + y = 10 liters
B) .05x + .25y = 10 * .10
Multiply equation B) by -4
B) -.2x - y = -4 then add to equation A)
A) x + y = 10 liters
.8x = 6 liters
x = 7.5 liters of 5%
y = 2.5 liters of 25%
Answer:
no
Step-by-step explanation:
1 4/5 = 1 8/5 if you make a common denominator
Answer:
-5x from both sides
Step-by-step explanation:
When converting an equation to slope-intercept form, you need to isolate the y. The first step in isolating the y is to remove 5x from both sides of the equation:
5x - y = 7
5x - 5x - y = 7 - 5x
-y = 7 - 5x
Now it's just -1y on one side of the equation.
The answer is A. .3 because do find the percent from a decimal you need to move the decimal point two to the right, so in this case it will be 30 or 30%
