Answer:
The average number of students in kindergarten classes is 21.
Step-by-step explanation:
To do this, just add them up and divide by the total number (which is 10).
8 / x = 12 - 3(8)
8 / x = 12 -24
8 / x = -12
x = -0.66666666667
Check your work
8 /(-0.66666666667) = 12- 3(8)
-12 = 12 - 3(8)
-12 = -12
x = -0.66666666667 Exactaly (Ten 6's One 7)
Hope this helps :)
Answer:
Yes.
Step-by-step explanation:
Any number raised to the power of 2 will be greater than the original number.
A positive number:
4² = 16
A negative number:
-3² = 9
Or:
0² = 0
2x+4=3x+2
2x=3x-2
-1x=-2
X=2
