12/(5x-2)=(12+4)/6x
72x=80x-32
8x=32
x=4
4 2/3. add the twos and keep the 2/3
Answer:
$3900
Step-by-step explanation:
Given data
P= $30,000
r= 6.5%
t= 10 years
t= 12 years
Let us find the SI interest after 10 years
SI= PRT/100
SI= 30000*6.5*10/100
SI= 1950000/100
SI= 19500
Let us find the SI interest after 12 years
SI= PRT/100
SI= 30000*6.5*12/100
SI= 2340000/100
SI= 23400
The extra amount paid is
=23400- 19500
=$3900
Answer:
Step-by-step explanation:
1/3Bh
1/3[1/2(10x20)](19)
1/3(100)(19)
1/3(1900)
633 1/3
Answer:
(x,y)=(-1,-4)
Step-by-step explanation:
-4x + y = 0
+4x +4x
y=4x
-5x - 2y = 13
+5x +5x
-2y = 5x+13
-2(4x) = 5x+13
-8x=5x+13
-5x -5x
-13x/-13=13/-13
x=-1
Thus:
y=4x
y=4(-1)
y=-4
