The current mean is 3 (15/3)
adding 9 would make the mean 4 (24/6)
therefore the mean would increase by 1
Answer:
A = 340 adult.
C = 398 children.
Step-by-step explanation:
Let the number of children be C
Let the number of adults be A
Translating the word problem into an algebraic equation, we have;
A + C = 738 .......equation 1
1.5C + 2C = 1306 .......equation 2
A = 738 - C .......equation 3
Substituting eqn 3 into eqn 2, we have;
1.5(738 - C) + 2C = 1306
1107 - 1.5C + 2C = 1306
1306 - 1107 = 2C - 1.5C
199 = 0.5C
C = 199/0.5
<em>C = 398 children. </em>
Now, to find the value of A.
From equation 3;
A = 738 - C
A = 738 - 398
<em>A = 340 adult. </em>
The operator 
is transitive, which means exactly that
That's the only thing you can deduce from your statement.
Answer:
y≥14
Step-by-step explanation:
Add 27 to both side so
y-27+27≥-13+27
so
y≥14
