One number is 11 less than the other number. If their sum is increased by 8, the result is 71. Find the numbers.
Tsimmuaj Reply
26 + 37 = 63 + 8 = 71
how do we know the answer is correct?
23 is 11 less than 37. 23+37=63. 63+8=71. that is what the question asked for.
23 +11 = 37. 23+37=63 63+8=71
by following the question. one number is 11 less than the other number 26+11=37 so 26+37=63+8=71
your answer did not fit the guidelines of the question 11 is 41 less than 52.
71-8-11 =52 is this correct?
let the number is 'x' and the other number is "x-11". if their sum is increased means: x+(x-11)+8 result will be 71. so x+(x-11)+8=71 2x-11+8=71 2x-3=71 2x=71+3 2x=74 1/2(2x=74)1/2 x=37 final answer

Joy is preparing 20 liters of a 25% saline solution. She has only a 40% solution and a 10% solution in her lab. How many liters of the 40% solution and how many liters of the 10% solution should she mix to make the 25% solution?
Wenda Reply
15 and 5
32 is 40% , & 8 is 10 % , & any 4 letters is 5%.
It felt that something is missing on the question like: 40% of what solution? 10% of what solution?
its confusing
3% & 2% to complete the 25%
because she already has 20 liters.
ok I was a little confused I agree 15% & 5%

A veterinarian is enclosing a rectangular outdoor running area against his building for the dogs he cares for. He needs to maximize the area using 100 feet of fencing. The quadratic equation A=x(100−2x) gives the area, A , of the dog run for the length, x , of the building that will border the dog run. Find the length of the building that should border the dog run to give the maximum area, and then find the maximum area of the dog run.
