To see, which plane traveled <span>farthest of shortest distance we have to write all the numbers in the same accurance
3.345
3.35 => 3.350
3.3 => 3.300
The longest is 3.35
The shortest is 3.3</span>
Answer:
x = -8
Step-by-step explanation:
1) 5x + 7= 7x +23
Move the terms
2) 5x + 7 -7x = 23
Collect like terms
3) 5x -7x = 23 - 7
Calculate
4) -2x = 16
Divide both sides by <em>-2</em>
5) x = -8
A scale drawing is an enlarged or reduced drawing of an object that is similar to an actual object. Maps and floor plans are smaller than the actual size. A scale drawing of a human cell is larger than the actual size.
On a map, the equal sign in 1 in. = 30 mi does not mean that the two quantities are equal, as it would in an equation.
A scale is the ratio that compares a length in a drawing to the corresponding length in the actual object. If a 30-mile road is 1 in. long on a map, you can write the scale of the map in these three ways:
