Answer:
49/20 miles or 2.45 miles
Step-by-step explanation:
LCM(1,2,3,4,5,6,)=60
10/60+12/60+15/60+20/60+30/60+60/60=147/60=49/60 or 2.45
3x-9 would equal 3(x-3) because you factor the 3 out of the 9.
Answer:
A' = { 2,4,6,8,10,12,14,16,17,18,19}
A' U B = {2,4,6,8,10,12,14,16,17,18,19,7,11,13}
Step-by-step explanation:
A = {1,3,5,7,9,11,13,15}
B = {7,11,13,17,19}
For num 4 the answer to six is 22 the reason is this formula so write this down for n aswell
n(n+1)/2+1 the example could be as we know for 1 cut we always will have 2 slices so 1(1+1)/2+1 is 2 and for 6 cuts 6(6+1)/2+1 is 22 therefore the answer to 6 cuts is 22 and to n cuts is the formula n(n+1)/2+1
Answer:
∠ XMZ = 74°
Step-by-step explanation:
Since the corresponding arcs on the 2 circles are congruent , then the central angles are congruent, that is
6x - 88 = 3x - 7 ( subtract 3x from both sides )
3x - 88 = - 7 ( add 88 to both sides )
3x = 81 ( divide both sides by 3 )
x = 27
Then
∠ XMZ = 3x - 7 = 3(27) - 7 = 81 - 7 = 74°
