Answer:
<h2><em><u>
11.2 - B to C</u></em></h2><h2><em><u>
12 - B to A</u></em></h2><h2><em><u>
8.8 - A to C</u></em></h2>
You have to multiply all the sides by 4.
B to C = 2.8*4
2.8 * 4 = 11.2
B to A = 3*4
3*4 = 12
A to C = 2.2*4
2.2*4 = 8.8

Answer:
-3 / 2
Step-by-step explanation:
- 5x - 6 = 3x - 9
- 5x - 6 + 6 = 3 x - 9 + 6
- 5x = 3x - 3
- 5x - 3x = 3x - 3 - 3x
- 2x = - 3
- 2x / 2 = -3 / 2
- The X = -3 / 2
Let x be ml of 5% soln.
let 500-x be ml of 25% soln.
.
x*.05=.05x
(500-x)*.25=125-.25x
500*.20=100
.
.05x+125-.25x=100
-.2x=-25
x=-25/-.2
x=125 ml of 5% soln.
500-x=375 ml of 25% soln.
.
Check:
125*.05= 6.25
375*.25=93.75
