Answer:
-80 is a real rational number
Step-by-step explanation:
it is real, and it is rational. It isn't irrational, and it is not a natural number either
I'll offer you a deal in return for your 5 points: I'll solve it . . . . You check it.
<u>-1/2x - 7 = -11</u>
Add 7 to each side: -1/2 x = -4
Multiply each side by 2 : - x = -8
Multiply each side by -1 : <em> x = 8</em>
Take it Allalala !
A) there are 3 times 1/3 in each hour: so we have to multiply the original number by 3: 3*13=39!!
b)
so, 13 pages in 1/3 of an hour
for this we have to divide the time needed for the 13 pages by 13:

so each page requires

of an hour, which is approximately 1.5 minutes.
Answer:
116°
Step-by-step explanation:
In a triangle, the sum of all interior angles is 180°
<PRS + <RSP + <SPR = 180°
51° + <RSP + 65° = 180°
<RSP = 180° - 65° - 51° = 180° - 116° = 64°
Since, <PST and <RSP are supplementary angles,
<PST + <RSP = 180°
<PST = 180° - 64° = 116°
Here, Time = Distance / speed
Substitute your known values,
t = 266 miles / 76 mph
t = 3.5 hours
In short, Your Answer would be: 3.5 Hours
Hope this helps!
