Answer:

  62, 64, 66

Step-by-step explanation:

I like to work "consecutive integer" problems by considering the average, or middle value. If we call that x, then the problem statement tells us ...

  (x -2) +(x +2) = 128

  2x = 128 . . . . . collect terms

  x = 64 . . . . . . . divide by 2

The middle integer is 64, so the three even integers are 62, 64, 66.

spin [16.1K]
Okie doke. 1cm on the map equals 500 meters. The distance from the gate to the ferris wheel on the map is 2.5cm. To find the actual distance, multiply the length on the map by the distance per centimeter. 500 * 2.5 is 1,250. The actual distance is 1,250 meters.

Note: When it comes to problems like these, you must always multiply the distance on the map by the scale unit (in other words, the actual distance on how far it is per the smaller unit).

OlgaM077 [116]

Answer:

x=9

Step-by-step explanation:

2x=8+10           | Add 10 to both sides

2x=18                 | Add. <em>Optional; not included in your question.</em>

<em />x=9<em>                    </em>| Divide by 2 on both sides.

How does algebra affect how people can learn from each other?
pantera1 [17]

Algebra is Faster And Better Than “Basic” Math

Just as multiplying two by twelve is faster than counting to 24 or adding 2 twelve times, algebra helps us solve problems more quickly and easily than we could otherwise. Algebra also opens up whole new areas of life problems, such as graphing curves that cannot be solved with only foundational math skills.
