Answer:
1/2.(x+12)=4x-1
x+12=2(4x-1)
x+12=8x-2
Group like terms
12+2=8x-x
14=7x
Divide both sides by 7
x=2
Step-by-step explanation:
1)5 2)6 3)17 because h(x)+k(x)=3x-1
Answer:
okay so you multiply the price of the snakes by how much he bought which is $5.00 so you can subtract $5 - $8 and you get $3.00 so that is how much is left over. Now you want to divide $3.00 by 2 and now you get $1.50. So each soda costed $1.50
5. The 5th figure will have 30 tiles.
6. The 6th figure will have 42 tiles.
7. The pattern is non-linear (quadratic).
8. The 20th figure can be made with 420 tiles.
_____
The Nth figure is made with n*(n+1) tiles. To answer question 8, you must solve
.. n(n +1) = 420
.. n^2 +n -420 = 0
.. (n +21)(n -20) = 0
.. n = 20 or -21 . . . . the negative solution is extraneous
