Answer:
There are 650 cannonballs
Step-by-step explanation:
If you look closely in the picture, you can see that:
- 1st row has 1 ball
- 2nd row has 4 balls
- 3rd row has 9 balls
- 4th row has 16 balls
etc. etc.
We can see that the number of balls is the square of the row number. There are a total of 12 rows. So, rest of the rows has:
- 5th row has 25 balls
- 6th row has 36 balls
- 7th row has 49 balls
- 8th row has 64 balls
- 9th row has 81 balls
- 10th row has 100 balls
- 11th row has 121 balls
- 12th row has 144 balls
If we add up all those, we get total number of balls:

There are 650 cannonballs
If it’s a triangle then it has to equal 180
so 48+54+x=180
48+54=102
180-102=x
x=78
<u><em>Answer: x<-6 *The answer should be the negative sign.*</em></u>
Step-by-step explanation:
subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
subtract 5 both sides of an equation.
5-2x-5>17-5
simplify.
-2x>12
multiply by -1 both sides of an equation.
(-2x)(-1)<12(-1)
simplify.
2x<-12
divide by 2 both sides of an equation.
2x/2<-12/2
-12/2=-6
12/2=6
6*2=12
12/6=2
x<-6
Hope this helps!
Thanks!
Have a great day!
5+3x=23 x=6 the answer is 6
