I did this test too! The answer was (-9, 0)
Make them have common denominators: 14/8(3/3)=42/24, 15/12(2/2)=30/24, 42/24+30/24. Add numerators: 42+30=72, 72/24. Simplify: 72/24=3, 24/24=, 3/1=3. 3 is your answer :)
Answer:
.9p
Step-by-step explanation:
The discount is the original price times 10%
p* .10= .1p
Subtract this from the original price
p - .10p
.9p
The new price is .9p
6!=6*5*4*3*2*1=720
Pretty sure this is correct
