She bought 4 brushes at $3 each
And 8 tubes of paint at $ .50 each
3x4=12
.50x8=4
12+4=16
Answer:
Step-by-step explanation:
The odd numbers.
Suppose you have 31 and 27 when you add these two together, you get 58 which is not an odd number.
If you need a more mathematical proof, you could do it this way.
2x+1
2x is even. Anything multiplied by 2 is even. When you add 1 you get an odd number
So continue on
2y + 1 is the other number.
2x + 1 + 2y + 1 = 2(x + y) + 2
2 (x + y ) is even. When you add 2 to it, nothing changes. The result is still even.
N÷3+1 or can be stated as 3÷n+1
2 consecutive odd integers...x and x + 2
x + (x + 2) = 36
2x + 2 = 36 <===
