The amount invested by Mr.Smith in 5% is $240 .
<u>Step-by-step explanation:</u>
We have , Mr. Smith invests a certain amount of money at 8% and twice as much at 5%. If his annual income from the two investments is $720 . Let us suppose that Mr.Smith invest $x so :
Amount of money invested in 5% is . And, amount of money invested in 8% is twice that of 5% i.e. .
Now, total investment is $720 so,
+( ) = $720

The amount invested by Mr.Smith in 5% is i.e.. ∴ The amount invested by Mr.Smith in 5% is $240 .
It will either have infinite solutions or no solutions.
If the lines are parallel, they will have no solutions.
If the lines are on top of each other, they will have infinite solutions.
So the answer is false.
This kind of problem assumes that the two people working together work for the same amount of time.
Renee can sew a quilt in 16 hours, so she can sew 1/16 of a quilt each hour. Gerena sews a quilt in 12 hours, so she can sew 1/12 of a quilt each hour.
Use the variable t represent the time Renee and Gerena work together (measured in hours). The part of a quilt Renee sews is . the part of the quilt that Gerena sews is
Together, they sew one quilt, so
Multiply all the terms by 48 (the Least Common Multiple of 16 and 12).
hours.
