Answer:
-4, 14+(-5) (-0.8), 14+ (3) (-0.8), 16.4
Step-by-step explanation:
The change in temperature for -5 is -4
The expression for -5 is 14+ (-5) (-0.8)
The expression for 3 is 14+ (3) (-0.8)
The actual temperature for 3 is 16.4
I did the math.
Answer:
3x + 4y = -36
y = 2x - 9
3x + 4(2x - 9) = -36
3x + 8x - 36 = -36
11x - 36 = -36
11x = 0
x = 0
y = 2(0) - 9
y= 0-9
y = -9
(0, -9) is the answer

Answer:
The car will travel 29 1/3 miles in 44 minutes, 40 miles in an hour.
Step-by-step explanation:
First, find how far the car can travel in one minute.
(1 1/2)/(2 1/4)=(2/3)
Then multiply the amount of time in minutes.
(2/3)*44= 29 1/3
(2/3)*60=40
Answer:
the answer is 2.90
Step-by-step explanation:
Picture a rectangle, if one side is 3.4 then the other side 3.4. Add those two togerther gives you 6.8. Now you can subtract 6.8 from the perimeter which is 12.6 then that gives you 5.8. Then you split the 5.8 which give you 2.90 which is the length of the rectangle. So if you label all the sides of the rectangle like this 3.4 + 3.4 + 2.90 + 2.90 = 12.6
