Step-by-step explanation:
6n-10=50
6n=60
n=10
rlu=6n-10
=6×10-10
=60-10
50
W + 2w = 60
this equation is wrong
Ur x axis will be the number of cans and ur y axis will be the weight in oz
u will label ur x axis( the number of cans) in intervals of 1......from 0 to 4
u will label ur y axis (the weight) in intervals of 10....from 0 to 40
ur equation would be : y = 10x
points on this line are : (0,0), (1,10), (2,20), (3,30), (4,40)
Solve the equation using substitution?
The annual rate of interest per year is 8%
<u>Solution:</u>
Given:- Principal (p) = 4600 rupees, Time –Period (t) = 5 years, Total amount(A) = 6440 rupees
First we will calculate the Interest and then using formula of simple interest we will calculate the rate of interest
Interest = Amount – Principal
Interest = 6440 – 4600 = 1840
Now using the formula of simple Interest and on putting values we get,

Where "P" is the principal and "R" is the rate of interest per annum and "T" is the time period


Hence, the required rate of interest per year is 8%
