Answer:
Step-by-step explanation:
8 pounds of flour = 5 dollars
1 pound of flour = x
Cross multiply
8x = 1*5 Divide by 8
8x/8 = 5/8
5/8 = 0.625
Therefore x = 0.625 dollars will buy 1 pound of flour.
Rounded x = 0.63
if the line is higher on the right-hand-side than on the left-hand-side, the slope is positive.

Answer:
7
Step-by-step explanation:
Try taking everything besides the x away. So the opposite of positive 7 is negative seven on the opposite side. 21-7 is 14 and 2x=14 is all that remains. The opposite of 2 times x is 2 divided by x and since we want to keep the x we divide the 2 on the other side, 14/2 is 7. x=7 is what remains.
