Answer:
a = -3
Step-by-step explanation:
3a - 6a + 2 = 8a + 20 - 5a
Combine Like Terms
-3a + 2 = 3a + 20
-2 -2
-------------------------------------
-3a = 3a + 18
-3a -3a
-------------------------------------
-6a = 18
---- ----
-6 -6
a = -3
Convert 3h and 45 min to hours so it will be 3.9 hours
Then say:
Distance = speed ✖️time
= 122 km/h ✖️3.9h
=475.80 km
He will travel 475.80 km
Hope this helps ;)
Answer:
perimeter = 322.5 ft ( to the nearest tenth of a foot)
Step-by-step explanation:
Length the length of the sides of the square be L
Area of a square = L²
∴ 6,500 = L²
L = √(6,500)
L = 80.6226
Next Let us calculate the perimeter
Perimeter of a square = L + L + L + L = 4L
perimeter = 4 × 80.6226
Perimeter = 322.4904 ft
perimeter = 322.5 ft ( to the nearest tenth of a foot)
<em>N:B rounding to the nearest tenth of a foot is same as rounding to 1 decimal place.</em>
