-10(1-9x) +6(x-10)
-10+90x+6x-60
96x-70
so d is the answer
Answer:
Vehicle one he put $10000
Vehicle two he put $1000
Step-by-step explanation:
Interest= PRT/100
Interested= x
P1 +P2= $20000
X1+x2= $1200
R1= 5%
R2= 7%
(P1*5*1)/100= X1
5p1=100 X1.....
P1= 20X1...
(P2*7*1)/100= X2
7p2= 100X2
P2= 100/7 X2
P1 +P2= $20000
20X1 + 100/7 X2= 20000
7X1 +5x2= 7000...equation one
X1+x2= 1200 ....equation two
Multiplying equation two with 7
7X1 +7X2= 8400
7X1 +5x2= 7000
Solving simultaneously
2X2=1400
X2= 700
P2= 100/7 X2
P2= 100/7 (700)
P2= 10000
But X1+x2= $1200
X1= 1200-700
X1= 500
P1= 20X1
P1= 20(500)
P1= 10000
Vehicle one he put $10000
Vehicle two he put $1000
A cylinder is 12 feet high has a diameter of 10 feet in cubic feet
10 hours.
If you multiply 2 1/2 by 4, the product is 10.
