1, 3, 5, and 15
1 x 15 = 15, 3 x 5 = 15, 5 x 3 = 15, 15 x 1 = 15
3+6 is 8, and 53^2 is basically 53 x 53. 53^2 is 2809.
Answer:
9 years
Step-by-step explanation:
S.I = PRT/100
now since you’re aiming at $20,000 and what you deposited was $12,500, this means that you’re looking to raise 20,000-12,500 = $7,500 simple interest.
Hence, S.I = 7,500
P = 12,500
R = 6.5%
T = ?
Substituting these values into the simple interest equation:
7,500 = (12,500 * 6.5 * T)/100
T = (100 * 7,500)/(12,500 * 6.5)
T = 750000/81,250 = 9.23 approximately 9 years
Answer:
1. x = 4 and y = 1
2. x= 5 and y = 3
Use the examples below to complete 3 and 4.
Step-by-step explanation:
To solve each system of equations, use elimination.
1. Stack the equations and subtract to perform elimination.
2x + 2y = 10
- x + 2y = 6
-------------------------
x = 4
Substitute x = 4 into an equation to solve for y.
2(4) + 2y = 10
8 + 2y = 10
2y = 2
y = 1
2. Stack the equations and subtract to perform elimination.
3x + y = 18
- 2x + y = 13
-------------------------
x = 5
Substitute x = 5 into an equation to solve for y.
3(5) + y = 18
15 + y = 18
y = 3
Continue the same method for numbers 3 and 4.
Three. For these questions, ignore the positive or negative sign.
