Since 1 km = 1000 m, the lawnmowers top speed would be 8000 m/h.
If x>5......f(x)= x-5
if x <5......f (x)= -x+5
Circumference of a circle=2πr
Where r is radius
C=(2*2.2)π
C=4.4π
238 rounded to the nearest ten would be 240 because 8 is bigger than 5. So since its bigger we move the tens place (3) a number ahead (4).
Thats how we get 238 rounded to the nearest ten would be 240.
Hope I helped ya!!
M<A = m<C = 53
answer is B. 53
-------------
2x = 8
x = 4
answer
D. 4
--------------
y = 3x (1)
y + 12 = 6x so y = 6x - 12 (2)
from (1) and (2) you haev
3x = 6x - 12
3x = 12
x = 4
y = 4x = 4(3) = 12
answer
C. y = 12
