7* 2 3/7
= 17/7* 7
= 17 (because 7 and 7 cancel out)
The final answer is 17~
I would have to say -0.5 then positive 0.25 because the rule seems to be divide by -2.
Answer:
Step-by-step explanation:
Let us call the width of the rectangle "x." Since the length of the rectangle is five less than twice its width," we can express the length of the rectangle as 2x - 5 (since 2x = twice the width and - 5 indicates "five less").
***
Now, using x as the width and 2x - 5 as the length, we can create an equation. We know that the perimeter is 86 feet, and the perimeter of a rectangle is the same thing as adding up its sides together: length + length + width + width, or 2*length + 2*width. Thus, we can create the equation
2(length) + 2(width) = 86
Substituting in our expressions for width and length, we get
2(2x - 5) + 2(x) = 86
Now we can just solve for x
2(2x - 5) + 2x = 86
Distribute: 4x - 10 + 2x = 86
Add like terms: 6x - 10 = 86
Add 10 to both sides: 6x = 96
Divide both sides by 6: x = 16

Answer:
The second table.
Step-by-step explanation:
In the first table, the speed goes from 45 down to 43; then down to 41; then up to 42; then up to 43. It decreases and then increases. This is not the correct table.
In the second table, the speed goes from 45 up to 47; then up to 49; then down to 48; then down to 47. It increases and then decreases; this is the correct table.
To verify, we check the last two tables. The third table stays at 45, then decreases to 43 and 41. This is not correct.
The last table decreases from 45 to 43, then decreases to 41, then stays constant. This is not correct.
The second table is the only correct one.
