the perimeter of the field is 442
width=w
the length of the field is 9 yards less than quadruple W
L=4x - 9
the perimeter is P=2L+2W
you can plug in the values
P= 2(4w-9) + 2W
plug in 442 for P
442= 2(4w- 9) + 2W
442= 8w - 36 + 2W
478 =8w + 2W
478= 10W
47.8 is your answer!!!

Answer:
Y = 2
Step-by-step explanation:
Solve for Y:
(3 + 5)×2 Y = 5×8 - 2×4
3 + 5 = 8:
8×2 Y = 5×8 - 2×4
5×8 = 40:
8×2 Y = 40 - 2×4
-2×4 = -8:
8×2 Y = -8 + 40
8×2 = 16:
16 Y = 40 - 8
40 - 8 = 32:
16 Y = 32
Divide both sides of 16 Y = 32 by 16:
(16 Y)/16 = 32/16
16/16 = 1:
Y = 32/16
The gcd of 32 and 16 is 16, so 32/16 = (16×2)/(16×1) = 16/16×2 = 2:
Answer: Y = 2
Answer:
x=ln(61)/ln(4)
Step-by-step explanation:
4^x+3=64
4^x=64-3
4^x=61
x=ln(61)/ln(4)
Knowing the halfway point (which is 5) helps you so you know wither or not the hundred thousands place goes high or stays the same.
So, for this problem 138,202 would round out to 100,000 because the 3 is below 5 so the hundred thousands place stays the same.
