Answer:
1 23 is the correct answer hope it's helpful to you
The next pattern is 364...
the pattern is by multiples of 3 added to the preceding number;
example, 1+3= 4 that's 3
4+9=13 because 3*3 is 9
13+27=40 coz 9*3 is 27
40+81=121 coz 27*3 is 81
121+243=364 coz 81*3 is 243
and so on and so forth..
hope this helps!
Answer:
Step-by-step explanation:
x+90+90+78=360(sum of 4 angles is always 360 degree)
x+258=360
x=360-258
x=102
Answer:
x= - 30
Step-by-step explanation:
x-9=0.7x+0.6
x-9=1.3x
x-9-1.3x=0
x-1.3x=9
x(1-1.3)=9
-0.3x=9
x= - 9/0.3
x= - 30
