Answer: 54

Step-by-step explanation: 2x -18 = 90

                                             2x = 108

                                             x = 54

*Complement means complementary angle. Complementary angles always add up to 90 degrees!

23. The letters of the alphabet are written on
Alla [95]

Answer:

21/676

Step-by-step explanation:

The total number of letters of the alphabet will be the total outcome which is 26 alphabets.

If consonant numbers are drawn out, the probability of drawing a consonant will be total consonants/total alphabets

Total consonants in the alphabet is 21.

Probability of drawing consonants = 21/26.

Since all the consonants are replaced before drawing a Z, our total outcome will not change i.e it will still be 26.

Probability of drawing a letter Z will be 1/26.

Therefore, the probability of drawing a consonant,replacing it, and then drawing a Z will be;

21/26×1/26

= 21/676

Make a conjecture about the sum of primes based on the following pattern:
Setler [38]
14= 7+7
16= 8+8
18= 9+9
20= 9+11
22= 10+12
24= 12+12
26= 7+8+11

-26 times a number minus 22 is equal to 90 less than the number.
IgorLugansk [536]

Answer:

x = \frac{68}{27}

Step-by-step explanation:

Let x be the number

  1. Write it out: -26x - 22 = x - 90
  2. Combine like terms: -27x + 68 = 0
  3. Subtract 68 from each side, so it now looks like this: -27x = -68
  4. Divide each side by -27 to cancel out the -27 next to x. It should now look like this: x = \frac{68}{27}  

I hope this helps!
