To find the rate (r) needed to cover a distance of 212.5 miles in a time of 2.5 hours, we can rearrange the formula r = d/t to solve for r.
r = d/t
r = 212.5 miles / 2.5 hours
r = 85 mph
Therefore, you must travel at a rate of 85 mph to cover 212.5 miles in 2.5 hours.

To simplify the expression 12[62 Γ· (52 β 42) + 7], we first solve the expression within the parentheses.
(52 - 42) = 10
Next, we divide 62 by 10:
62 Γ· 10 = 6.2
Now we substitute this value back into the expression:
12[6.2 + 7]
Next, we simplify the addition within the bracket:
6.2 + 7 = 13.2
Lastly, we multiply the result by 12:
12 * 13.2 = 158.4
Therefore, the simplified form of the expression is 158.4.

StartFraction 10yz over -2z EndFraction
Note that we can simplify by cancelling out the z terms in the numerator and denominator:
StartFraction 10ycross(d) cross(z) over -2 cross(z) EndFraction
This simplifies to:
StartFraction 10y over -2 EndFraction
Finally, we can simplify further by dividing both terms of the fraction by -2:
StartFraction 10y over -2 EndFraction = -5y
Therefore, the simplified form of the expression is -5y.

To find the temperature at the start of the day, we need to subtract the total increase in temperature from the temperature at the end of the day.
Given that the temperature increased by 8 degrees and then by 4 degrees, the total increase is 8 + 4 = 12 degrees.
To find the temperature at the start of the day, we subtract the total increase from the temperature at the end of the day:
64 - 12 = 52
Therefore, the expression that shows what the temperature was at the start of the day is 64 - 8 - 4.

To find the value of xy/w when x = -3, y = 4, and w = -6, we substitute the given values into the expression:
xy/w = (-3 * 4) / (-6)
Simplifying the numerator and denominator:
(-12) / (-6) = 2
Therefore, the value of xy/w when x = -3, y = 4, and w = -6 is 2.
