Answer:Let the amount invested in each be
A and B
A+B=5000
0.1A+0.15B=630
0.1(5000-B)+0.15B=630
500-0.1B+0.15B=630
0.05B=130
B=2600
A=2400
Step-by-step explanation:
Answer:
x = 4
x * 5 = 20 * 1
area= 264.5 unit square
let the width of the rectangle be x units then the length would be 2x units
perimeter = 2(l+b)= 2(2x+x)=2(3x)=6x
69=6x
x=69/6=11.5units
width is 11.5 units and length is 23 units
area= lxb= 11.5* 23= 264.5 units square
Answer:2.624
