Answer:
8 is 4% of 200, 1% of 200 is 2
60/100 is 3/5 so Anna colored 60% of the paper blue
Distribute the 3 to both x and 2
3(x + 2) = 3x + 6
3x + 6 + 2x = -4
Combine like terms
(3x + 2x) + 6 = -4
5x + 6 = -4
Isolate the x. Note the equal sign. What you do to one side, you do to the other. Subtract 6 from both sides
5x + 6 (-6) = -4 (-6)
5x = -4 - 6
5x = -10
Divide 5 from both sides
5x = -10
5x/5 = -10/5
x = -10/5
x = -2
-2 is your answer for x
hope this helps
Answers:
2% bond: $11000
4% bond: $13000
========================================================
Explanation:
x = amount invested in the 4% bond
y = amount invested in the 2% bond
Amounts are in dollars
The two amounts add to $24,000 so
x+y = 24000
y = -x+24000 is one equation to set up
0.04x = interest earned from the 4% bond
0.02y = interest earned from the 2% bond
0.04x+0.02y = total interest earned = $700
0.04x+0.02y = 700 is another equation to set up
------------
The system of equations is
Apply substitution. Solve for x.
0.04x+0.02y = 700
0.04x+0.02(-x+24000) = 700
0.04x-0.02x+480 = 700
0.02x= 700-480
0.02x= 220
x= 220/(0.02)
x = 11000
Use this to find y
y = -x+24000
y = -11000+24000
y = 13000
Answer:
A) added to both sides of the equation
