Answer:
Initial amount P = $12000
Interest after 2 years I = 4%*2 = 8%
<u>Investment into Trust fund:</u>
- $12000 + $5000 + 0.08*$12000 = $17960
<u>Interest amount to exceed $20000:</u>
<u>Time required to get $2040:</u>
- 17960*0.045x = 2040
- 808.2x = 2040
- x = 2040/808.2
- x = 2.52 years
The investment will exceed $20000 in the second half of the third year

. n=70+x.
=994+15x
we have
mean=sum/n
14.44=
14.44=
doing crisscrossed multiplication
(70+x)*14.44=994+15x
1010.8+14.44x=994+15x
15x-14.44x=1010.8-994
0.56x=16.8
x=16.8/0.56
x=30
-8 - 5n = 64 + 3n
+5n +5n add 5n to both sides, 5n's cancel out on the left.
______________
-8 = 64 + 8n
-64 -64 subtract 64 on both sides, 64's cancel out on the right.
______________
-72 = 8n
___ ___ divide 8 on both sides, 8's cancel out from the right.

Answer:
Line 1
Step-by-step explanation:
Since x=3 and y=-6, just plug those two values in both of the equations.
Line1: (3)-(-6)=9 This would be the answer
Line2: 3(3)+3(-6) = -9 This is the incorrect answer because it should 3
