M * n = a * c
Since a and b are positive and c is negative.
So, a * c is negative which means that m * n is negative, i.e. m is positive, n is negative.

Also m + n = b and since b is positive, then |m| > |n|.

Therefore, option C is the correct answer.

Answer:

Step-by-step explanation:

Wrong. I just took the test and it's D.

Here's why:

when ax2-[mx+nx]-c

m and n need to have a positive and a negative coefficient.

if m is positive and a n is negative then n needs to be greater than m so the solution will also be negative to satisfy the need for [mx+nx] to be negative.

Rocky thinks of an odd integer adds the next two consecutive integer which of these could be the sum
tekilochka [14]

Answer:

C

Step-by-step explanation:

1. Let x be the odd integer. Let y be the sum.

x + (x + 1) + (x + 2) = y

3x + 3 = y

Adding two consecutive integers to an odd integer will result in an even integer.

So, you can eliminate choices B and D since they are odd.

Lastly, plug in choices A and C for y and choose the answer that makes x an integer.

Choice C would give you the correct result.

3x + 3 = 44562

3x = 44559

x = 14853

The price of an item has been reduced by 40%. The original price was $66. Find the price of the item now.
serious [3.7K]

Answer:

$39.60

Step-by-step explanation:

We are finding 66 - 40%

66 less 40% = 60% of 66

60% of 66 is the price of the item now.

Convert 60% to decimal form by dividing by 100.

60%/100 = 0.60

Multiply the decimal form by 66

66 X 0.6 = 39.60

Since we are dealing with money, keep 2 decimal places, even if the last digit is 0.

The price of the item now is $39.60.
