Answer:
x= (4z-4)/3
Step-by-step explanation:
3z+8=12+3x-z
3z + z +8 -12 = 3x
4z - 4 =3x
x= (4z-4) / 3
First you add up the number of coins in total so:
16+28+32+4
which equals: 80
Then to find 15% you have to do this:
80 divided by 100 then multiply by 15 which is 12.
The answer is 12.

Answer:
8/14
Step-by-step explanation:
The probability of getting a consonant is the sum of the total consonants divided by the total number of letters. The consonants in the word ADMINISTRATION are 8 in number (D,M,N,S,T,R,T,N) while the vowels in the word are 6 in number (A,I,I,A,I,O).
Therefore, the sum of the letters in the word ADMINISTRATION is 14.
The probability of getting a consonant is equal to;
<em>Sum of Consonants/ Sum of the letters </em>
which is 8/14.
Since the two numbers are divisible by 2, we could break the fraction further to get 4/7.
