Answer:
Factoring
Step-by-step explanation:
x^2 + 7x = x(x + 7) = 0
So
x = 0 or x = -7
Answer:
Rs 937.50
Step-by-step explanation:
Rs 750 for 4 years at 6 1/4% interest:
Simple interest is found using i = p*r*t, where p is the principal, r is the interest rate as a decimal fraction, and t is the number of years.
Here, i = (Rs 750)*0.0625*4 = Rs 187.50
The amount (that is, principal plus simple interest) will be:
Rs 750 + Rs 187.50 = Rs 937.50
<span>I can solve for x and y
A) 2x - 4y = 12
A) 2x = 4y + 12
A) x = 2y + 6
Substituting into B
B) 3* (2y +6) - 5y = 20
B) 6y + 18 -5y = 20
B) y = 2
B) x = 10
