Given
first, convert
to base 25 to match the other term.
Substitute above identity into original equation:
Use substiution
above equation becomes
2/u-3u=1
multiply by u and solve for u:
=> u=2/3 or u=-1
case A:. u=2/3 =>
=>
case B: u=-1 =>
which does not give a real solution, so reject.
See graph below for confirmation of solution.
Jane = x years
Tom = x+8
*5 Years Ago
Jane= x-5
Tom= (x+8)-5=>x+3---------------------------
x+3=3(x-5)<span>x+3=3x-15
3x-x=18
2x=18
x=9
Jane = 9 years
Tome = 9+8 = 17 years</span>
Answer:
Blank 1: 64° (or 32°, depending on what the label applies to)
Blank 2: 42
Step-by-step explanation:
It is a common mistake to believe you have solved the problem when you have found the value of the variable(s) in the problem. You have correctly found the values of n (42) and m (9). However, that is not what the problem is asking for.
We cannot tell if the value (1/2n+11)° is referring to angle DAB, or to angle CAB. In any event, (1/2n+11)° = (1/2×42 +11)° = 32°.
If that is angle CAB, then angle DAB is twice that value, 64°.
If that is angle DAB, then angle DAB is 32°.

The side length CD is the same as any other side length in a rhombus, so ...
CD = 4m+6 = 4×9 +6
CD = 42 . . . . units
It would go like this 6(b-4)>30 would then be 6b-24>30 then you would have to add 24 to both the -24 and the 30 to get 6b>54 the you would have to divide 54 by 6 and after that your answer would be b> 9
40 4/5 is the answer i believe. Just message me if you need help okay sweetie? :)
