Step-by-step explanation:
My school supplyes us with a calculator and lucky for you it does scientific notation
22, i think because 3 times 3= 9, and 9 times 3 minus 5= 22
Answer:
5x - y = 10x + 3y = 4
5x - y = 4..... 1
10x + 3y = 4.....2
multiply by -2 in eq 1 in both sides
-10x + 2y = -8
10x +3y = 4
eliminate one variable by adding the equations
5y = -4
y = - 4/5
sub the value of y in..1
5x - y = 4
5x + 4/5 = 4
5x = 16/5
divide by 5 on both sides
x = 16/25
(x ; y)
(16/25 ; -4/5)
So one third means you mutilply by 3 so 3x5 is 15 model cars
