6, 12, 21, 10, then 4
Step-by-step explanation:
This is more difficult to answer than you would think, you can't actually see the picture when typing the answer
<span>7r²+9=1
</span><span>the equation is contradictory, just to prove
7r</span>² + 9 = 1
7r² + 9 -1 = 0
7r² + 8 = 0
<span>We write the equation in the form of products of
</span>
7 * (r² + 8/7) = 0
<span>the product is equal to 0 when one of the factors is zero
</span>
7≠0 ∨ (r² + 8/7) = 0
r² ≠ - 8/7
<span>any number squared is not negative.
</span><span>We proved that none of the factors is not equal to zero , so the right side of the equation is not equal to the left . The equation is contradictory</span>
19=10%X. 19/.10=190. X=190 :)

You have to do some trades or borrowing. But think about it this way:
You need 2 cents to make it to $31. Then it’s $9 to get to 40.
36 + 5 = 41
41 x 2 = 82
The answer is 82
