15.75+3.2*20=M;
M=15.75+64;
M=69.75.
Answer: 69.75.
So all you have to do is multiply 400 times 400 which is 160,000 and divide 169,000 to 2 which is 80,000
Answer: 6.111
Step-by-step explanation: first break it down
(12x4 + 9x3 – 10x2) ÷ 3x3
(48 + 27 - 20)/9
(75 - 20)/9
55/9
6.111
Let x be the number of cases of paper towels and y be the number of cases of soap. The system of linear equation that would best represent the given is,
x + y = 10
12x + 15y = 129
The values of x and y are 7 and 3.
Sarah both 7 cases of paper towel.
It is not possible for Sarah to buy exactly 20 bottles because first of all the cases contains only 12 bottles and 20 is not divisible by 12.
