Answer: $725
<u>Step-by-step explanation:</u>
Let x represent the amount invested at 8%, then $13,000 - x is the amount invested at 16%.
0.08(x) + 0.16(13,000 - x) = 1500
0.08x + 2080 - 0.16x = 1500
2080 - 0.08x = 1500
- 0.08x = -580
x = 7250

Answer:
4x + 12x = 320
16x = 320
x = 20
Step-by-step explanation:
This is because the diagram shows 4x + 12x and the total being, 320.
4x + 12x = 16x
and 320/16 = 20
so x = 20

Hey there!
Given equation :
... 0.2 ( x + 50 ) - 6 = 0.4 ( 3x + 20 )
Using the distributive property.
... 0.2x + 10 - 6 = 1.2x + 8
... 0.2x + 4 = 1.2x + 8
Subtract 4 on both sides.
... 0.2x = 1.2x + 4
Subtract 1.2x on both sides.
... - x = 4
... x = -4
Hence, the answer is -4.
Hope it helps!!
