If I'm understanding this correctly 20 rounded to the nearest ten would be 20
You didn't give any choices, but the equation looks like this: 17 = 2x + 5. Solving that for x tells you that he went on a big water slide 6 times. 2 times 6 plus 5 is the $17 he spent at the park. See how well that works out?
2x+4=24
-4 -4

2x=20
÷2 ÷2

X=10
So 10 stickers in each pack
The summation of negative 5 n minus 1, from n equals 3 to 12 can be
expressed as
n = 3/12
substitute the value of n to the equatio
-5n – 1
-5( 3/12 ) -1
-9/4
