A football player gains 7 yards, loses 4 yards, and gains 12 yards.
a. Write his gains and losses as integers.
b. If he started at zero where does he end up?
let Tm = temperature at midnight.
and T6 = temperature at 6 a.m.
-------------------------
midnight =====> 6 A.M.
Tm.....+8.....-20
Tm + 8 = T6
Substitute and solve.
Tm + 8 = -20
Tm = -20-8
Tm = -28 C.
Does That Help Or No?
i think that will work for that specific answer now i just need 2 more im sorry im just really stressed because i had an essay to do a test to do and this quiz quiz one i had to do and i just wanted to get them outta my overdues
i still need help though because i dont know the answers for the essay questions i have an ela one too but i need help
gonna have to start two new ones because i have ss and math tests
please tell me the other twoo
To solve the first problem, let's represent the temperature at midnight with an unknown variable, say "x".
Since the temperature rose 8°C from midnight to 6:00 a.m., we can express this as "x + 8".
At 6:00 a.m., the temperature was -20°C.
So, we can set up the equation:
x + 8 = -20
To find the value of "x", we need to isolate it on one side of the equation.
Subtracting 8 from both sides of the equation:
x + 8 - 8 = -20 - 8
x = -28
Therefore, the temperature at midnight was -28°C.
For the second problem, we need to calculate the total change in altitude of the hot air balloon during its descent.
The balloon descends at a rate of 320 feet per minute for 3 minutes.
To find the total change in altitude, we multiply the rate per minute by the number of minutes:
320 feet/minute * 3 minutes = 960 feet
Therefore, the balloon's total change in altitude is 960 feet.
For the third problem, let's represent gains as positive integers and losses as negative integers:
The football player gains 7 yards. We can represent this as +7.
The player loses 4 yards. This can be represented as -4.
The player then gains 12 yards, which can be represented as +12.
To find where the player ends up from his starting point of zero, we need to add up the gains and losses:
+7 yards - 4 yards + 12 yards = 15 yards
Therefore, the football player ends up 15 yards away from his starting point.
