Answer:
The solution is (1,2)
Step-by-step explanation:
- 2x - y = - 4
x + 2y = 5
Multiply the second equation by 2 so we can eliminate x
2( x + 2y) = 5*2
2x +4y = 10
Add this to the first equation
- 2x - y = - 4
2x +4y = 10
----------------------
3y = 6
Divide each side by 3
3y/3 = 6/3
y = 2
- 2x - y = - 4
x + 2y = 5
Multiply the first equation by 2 to eliminate y
2(- 2x - y) = - 4*2
-4x -2y = -8
Add this to the second equation
-4x -2y = -8
x + 2y = 5
------------------
-3x = -3
Divide by -3
-3x/-3 = -3/-3
x = 1
The solution is (1,2)

Step-by-step explanation:
Formulae for simple interest is;
A= P (1 + rt) Whereby;
A = Total Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
r = Rate of Interest per year in decimal; r = R/100
R = Rate of Interest per year as a percent; R = r * 100
t = Time Period involved in months or years
15300 = 3200 (1 + 106.5/100 *t)
15300/3200 = 1 + 1.065t
4.78125 – 1 = 1.065t
3.78125 = 1.065t
3.78125/1.065 = t
3.55 = t
Rounded off to the nearest whole number;
= 4
Standard form would be 1.46e-6 because the variable has one degree and the number 6 does not have a degree.
Answer:
First, you add 11 to the other side of the equals sign. So it would be 2x=k+11. Now, you divide 2 from x and do the same on the other side of the equals sign. so x= k+11
