Answer:
Finding a dime, 5/10
Finding a penny, 2/9
Step-by-step explanation:
add up the total number of coins, 10, and put the number of dimes over it
5/10
add up the total number of coins, 10, and subtract a dime, so there is 9 coins, but 2 pennies so 2/9
2 ( x - 3) = 2x 5
2x - 6 = 10x
2x - 10x = 6
-8x = 6
x = -6/8
x = -3/4
So, final answer is -3/4

Line 1:
Expanding the vertex form, we have
x² + 2·1.5x + 1.5² - 0.25 = x² +3x +2
Expanding the factored form, we have
x² +(1+2)x +1·2 = x² +3x +2
Comparing these to x² +3x +2, we find ...
• the three expressions are equivalent on Line 1
Line 2:
Expanding the vertex form, we have
x² +2·2.5x +2.5² +6.25 = x² +5x +12.5
Expanding the factored form, we have
x² +(2+3)x +2·3 = x² +5x +6
Comparing these to x² +5x +6, we find ...
• the three expressions are NOT equivalent on Line 2
The appropriate choice is
Line 1 only
