Find two consecutive integers whose sum is 67. Which of the following equations could be used to solve the problem?
Hunter-Best [27]
The desired answer is probably that
  2x + 1 = 67
is the equation that can be used to solve the problem. In this case, x represents the smallest integer.

_____
I like to work problems in consecutive integers by considering their average. Here, it is 67/2 = 33.5. The two consecutive integers whose average is 33.5 are 33 and 34, the solution to the problem. For this, the first equation applies, where x is the value halfway between the two integers. (This answer (2x=67) would likely get marked wrong by your computer grading system.)

Divide $200 in the ratio 3:2. What is the result?
s2008m [1.1K]

Answer:

b) $120 , $ 80

Step-by-step explanation:

Ratio = 3 :2

Total = 3 + 2 = 5

3/5 of 200 = \frac{3}{5}*200

                  = 3 * 40

                  = $ 120

2/5 of 200 = \frac{2}{5}*200

                 = 2 * 40

                  = $ 80
