Step-by-step explanation:
BC^2 + DC^2 = AC^2
6^2 + 4^2 =AC^2
36 + 16 = AC^2
52=AC^2
√52=AC
AC=7.2111
Answer:
y=0
Step-by-step explanation:
Answer:
it would be 58
Step-by-step explanation:
if you do 72 x 417 it would be 5 at the top and 360 would be at the bottom so it would be 417-360 which is 57 and the six at the top u would drop so now it is 576 so if you do 72 x 8 it would be 576 so u would put the 8 with the 5 and subtract the 576 - 576 and that is 0 BOOM
2 1/7 + 3/7 (3x-5)= - 4
2 1/7 + (9/7)x - 15/7 = - 4
15/7 + (9/7)x - 15/7 = - 4
(9/7)x = - 4
x = - 4 * 7/9 = - 28/9 = - 3 1/9
Answer is - 28/9 or - 3 1/9.
