Find two consecutive integers whose sum is 67. Which of the following equations could be used to solve the problem?

1 answer:

3 0

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.)

Find the midpoint of the line segment joining the points P1 and P2.

Karolina [17]

Answer:

M= (1, 7/2)

Step-by-step explanation:

M = midpoint

M= ((x1+x2)/2) , ((y1+y2)/2)

we have:

P1 = (4,2)

P2 = (-2,5)

x1= 4 y1= 2

x2= -2 y2= 5

we have:

M= ((4-2)/2) , ((2+5)/2)

M= (2/2 , 7/2)

M= (1, 7/2)

Multiple-Choice The average distance

murzikaleks [220]

Alright, so it would be helpful to think about this question in terms of units. You're given a distance (meters) and speed (meters per second). You're asked for time (which is in seconds).

If you do $\frac{meters}{meters/second}$ , your answer will be in seconds. So divide your distance (2.28 x 10^11 meters) by your speed (3.00 x 10^8 meters/second), and you should get your time!
