Change you’ll receive is = 0.09
you can only buy 11 because if you divide 20/11 it will give you 1.81 and if you multiply 11x 1.81 it will give you 19.91 which is close to $20 & that’s the most you can buy .
X/2 + x/2 = 2x / 2 or just x. So x = 8/12 which can be simplified by their greatest common factor of 4. Divide both top and bottom by 4. This gives you x = 2/3.
Your answer for that equation is x = 2/3
Not sure what you mean by "decompose" though.
I believe that the answer is B. y=-7x+41
Answer: 2.5%
3967.50 - 3450 = 517. 50
i = prt/100
i = 517.50, p = 3450, t = 6
517.50 = 3450 x r x 6/ 100
517.50 = 20700r/100
517.50 = 20700r
517.50/20700 = r
r = 0.025 = 2.5%
