Answer:
x = 6
Step-by-step explanation:
Step 1: Write equation
75 - 3.5x - 4x = 4x + 6
Step 2: Solve for <em>x</em>
- Combine like terms: 75 - 7.5x = 4x + 6
- Add 7.5x on both sides: 75 = 11.5x + 6
- Subtract 6 on both sides: 69 = 11.5x
- Divide both sides by 11.5: 6 = x
- Rewrite x = 6
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
75 - 3.5(6) - 4(6) = 4(6) + 6
75 - 21 - 24 = 24 + 6
54 - 24 = 30
30 = 30
0.07 (5000-x) + 0.15x= 480
Solve for x
350-0.07x+0.15x=480
0.08x=130
X=1625 invested at 15%
(5000-1625)=3375 invested at 7%

Answer:
32
Step-by-step explanation:
YZ = ⅗XY.
XY = 20
20 / 5 x 3 = 12
YZ = 12
XZ = YZ + XY
XZ = 20 + 12
XZ = 32
