When you multiply a negative and a positive you will get a negative answer so 3*7 is 21 so -3 * 7 is -21
Large box --> M
Small box --> m
M+m=80
70M+60m=5300
Now solve this system of equations. Very easy job now.
Answer:
Part A Answer = A=28
Part B Answer is B = 9/16 + C =0.56
Step-by-step explanation:
1 = A. 28 This is because the percentage rate works out at 43.75%
2. 9/16 also, 0.56 This is because 9/16 has decimal 0.56 we can work this out by looking at the inverse of 1 ; 1= 16 16/9 = 1.77/3.17 which adds to 4.94 = 10 x 0.49 4 representing 4 from 20 =16 and 9 representing the proportion.
