A three digit number would be 294. You could do 200+90+4
Only 3 and 9 are both the subset of odd numbers and the subset of multiples of 3.
Let the width =x
length = 6x
p=14x
28=14x
x=2
Answer:
-17
Step-by-step explanation:
3x-7=4x+10
Add 7 to both sides & simplify
3x-7=4x+10
+7 +7
3x=4x+17
Subtract 4x from both sides & simplify
3x=4x+17
-4x -4x
-x=17
*Negative x equals -1*
Divide both sides by -1 & simplify
