Hello,
a-3b=4 (1)
a-b=-2 (2)
(1)-(2)==> -2b=6
=>b=-3 and a=-2+(-3)=-5

Answer:
4.5%
Step-by-step explanation:
The interest is given by ...
I = Prt . . . . interest at annual rate r for t years on principal P
1008 = 5600r·4
1008/22400 = r = 0.045 = 4.5%
The annual interest rate on the loan is 4.5%.
Answer:
Step-by-step explanation:
If the triangle is equilateral :
2x +y/2 = 5x/3+y + ½ = 2/3x +2y +5/2
so the perimeter is : P = 3(2x +y/2) or 3(5x/3+y + ½) or 3(2/3x +2y +5/2)
the simplest is : P = 3(2x +y/2)
P = 6x + (3y)/2
Answer:
8 * 7
Explanation:
When you count the squares along the area, you will find that the base is 8 units, and the height is 7 units. The area of a square is equal to base * height, so the correct answer is 8 * 7.
