Yes it is, due to the fact that you can see exactly what you are subtracting because they are directing above and below each other. In all forms of math we subtract this way for a better understanding of what's needed to be subtracted.
Answer:
155 Degrees
Step-by-step :
(Time x Rate of Temp) + Initial Temp = Final Temperature
Ex. (6 * 15) + 65 = 155 Degrees
Answer:
The slope is -3/4 y intercept is (0,-5)
Step-by-step explanation:
X Y
-20/3 0
0 5
graph ^
y + 2= -3/4 ( x+4)
The correct answer would be C.
Length (L): 2w + 6
width (w): w
Perimeter (P) = 2L + 2w
240 = 2(2w + 6) + 2(w)
240 = 4w + 12 + 2w
240 = 6w + 12
228 = 6w
38 = w
Length (L): 2w + 6 = 2(38) + 6 = 76 + 6 = 82
Answer: width = 38 ft, length = 82 ft
