Answer:
25 % acid solution = 450ml
45% acid solution = 150ml
Step-by-step explanation:
Let
x = 25 % acid solution
y = 45% acid solution
x + y = 600
.25x + .45y = .30(600)
x + y = 600 (1)
.25x + .45y = 180 (2)
From (1)
x = 600 - y
Substitute x = 600 - y into (2)
.25x + .45y = 180
.25(600 - y) + .45y = 180
150 - .25y + .45y = 180
150 + .20y = 180
.20y = 180 - 150
.20y = 30
Divide both sides by .20
y = 30/0.20
= 150
y = 150ml
Substitute y = 150 into
x + y = 600
x + 150 = 600
x = 600 - 150
= 450
x = 450ml
25 % acid solution = 450ml
45% acid solution = 150ml
Answer:
5:40
Step-by-step explanation:
24 / 3 = 8
x / 5 = 8
x = 5 * 8
x = 40
Answer:
Step-by-step explanation:
5 - (x + 5) > -2(x + 4)
5 - x - 5 > -2x - 8
-x > -2x - 8
-x + 2x > -8
x > -8
The answer is
option D "<span>
5,950,000".</span>
Which would equal 5,950,000.
Hope this helps!
