Answer: -30r + 15
Step-by-step explanation:
first, we multiply the parenthesis by 20.
-20 x 1.5r + 20 x 0.75
then, we multiply/calculate.
-30r + 15
Answer:
Step-by-step explanation:
One loan from the local bank is a three year loan with a capital of $75000 and an annual interest of 5%.
Therefore simple interest form this loan for the year will be
⇒ Principal amount×Rate of interest×Time(in years)/100
⇒ 75000×5×1/100
Interest = $3750
Other loan is a one year loan with a principal of $21000 and annual interest of 4.5%
Therefore interest of first year from this loan will be
= Principal amount×Rate of interest×Time(in years)/100
= 21000×5×4.5/100
= $4725
Total interest of first year for both loans = 3750+4725 = $8475
To solve this equation, we have to use the distributive property to multiply 5y through the parentheses.
-45y - 15y^2 = 13
-15y^2 - 45y - 13 = 0
15y^2-45y-13=0
