7.3%
Step-by-step explanation:
Given:
<em>Formula for Rate of interest </em>
:
Where 
is the rate of interest.
dollars is the loan and
years is the time for which interest is to be paid
To find:
Solution:
Putting the given values in the formula:
Multiply the above value with 100 to find the percentage.
i.e.
Therefore, the answer is <em>7.3%</em>
If R is between Q and S then QR+RS=QS
given
QR=x+4
RS=3x-1
and QS=27
x+4+3x-1=27
combine like terms
4x+3=27
minus 3 both sides
4x=24
divide both sides by 4
x=6
sub back
QR=x+4
QR=6+4
QR=10
RS=3x-1
RS=3(6)-1
RS=18-1
RS=17
x=6
QR=10
RS=17
Answer:
23
Step-by-step explanation:
Taking an algebraic approach
let the number be n, then (n - 17) is 17 subtracted from number and
- 2(n - 17) = - 12 ( divide both sides by - 2 )
n - 17 = 6 ( add 17 to both sides )
n = 23
Thus Julio's number was 23
