The parallelogram<span>, rectangle, and </span>square<span> all have two pairs of parallel sides </span>
Answer:
x=5
y=1
Step-by-step explanation:
7x+4y=39
7*5=35
4*1=4
35+4=9
2x+4y=14
2*5=10
4*1=4
10+4=14
<span>x+2y=11
can be written as
x = 11 - 2y
substitute x into the other equation
</span>-8(11 - 2y) + 6y=22
<span>simplify
-88 + 16y + 6y = 22
-88 + 22y = 22
+88 +88 isolate y
22y = 110
----- -----
22 22
y = 5! now add Y into the equation to find X
</span>-8x+6(5)=22
<span>-8x+30=22
- 30 -30
-8x = -8
---- ----
-8 -8
x = 1 (1,5) Is the solution

Answer:
$2400
$12,400
Step-by-step explanation:
Simple interest equation:
PV(1+it)
we have
10000(1+.06*4)
10000(1.24)
12400
Subtract the PV to get the interest earned
12400-10000= 2400
We just found that the total would be 12,400 and so part B is already solved
