If you calculate the problem correctly you should end up with:
(A)-(3)
Which equals:
= -3
Hope this helps... have a good day!
Answer is the last choice
2a-4/1= -a-1/a-4
Cross multiply
(2a-4)(a-4)= -(a-1)
2a^2-8a-4a+16= -a+1
Bring right to left sign change signs
2a^2-8a-4a+16+a-1=0
Combine like terms
2a^2-11a+15=0
a= 2 b= -11 c= 15
Use quadratic formula
-b+-sq rt of b^2-4ac. Divided by 2a
-(-11) +- 11^2-4(2)(15) divided by 2(2)
11+-sq rt 121-120 divided by 4
11+1 /4. 11-1/4
12/4. 10/4
3. , 5/2
Answer:
$16.80
Step-by-step explanation:
This is because $21 times .20 is $4.2.
$21-$4.2= $16.80.
20-20=0 and 1+2 = 3 sooo my home would be nice thx for the points
Answer:
Amount after one year = $410
Error made = $260
Step-by-step explanation:
Number of quarters in one year = four quarters
Hence amount after one year = P(1+r)⁴
A = 325(1+0.06)⁴ = $410
Error made = 670 - 410 = $260
