We have a total of 178 6th and 7th graders. And we are informed that there are 12 more 6th graders the 7th graders. Let x = the number of 7th graders
x + (x + 12) = 178
Subtract 12 from both sides
x + x = 166
Add like terms
2x = 166
x = 83
So, there are 83 7th graders. And add 12 to find the number of 6th graders.
12 + 83 = 95
Answer:
Not sure what goes in the ( ) so best guess......
Step-by-step explanation:
5x^2+10x=5x
Move everything to one side:
=5x^2+10x+(-5x)
Combine like terms:
(5x^2)+(10x+(-5x))
Simplify:
5x^2+5x
Answer: in summary, a scale factor is simply a number that multiplies the dimensions of a shape. ... If the scale factor is three, then the perimeter of the new object will be three times the original perimeter. The area of a scaled object will be equal to the scale factor squared.
Step-by-step explanation:
For example, if you had a triangle with a base measuring 6 units, and a height measuring 3 units, the area would be 9 square units. If we scale it by 1/3, the triangle's base is 2 units, the height is 1 unit, and the area is 1 square unit. The dimensions were scaled by 1/3, but the area was scaled by 1/9 (1/3 * 1/3).
