x< 15 where x is the average that each person contributes.
This gives 3x <45, limiting the gift basket's total cost to < $45. (Actually ≤ 14.99 per person, so max cost is $44.97.
19. simple algebra
a <= -4 + 7
a <= 3
20.
since u divide and the co efficient is negative u flip the sign
-3m<15
m>-5
Answer:
a = - 3
Step-by-step explanation:
The equation has common factors x(x + 3) on both sides
For the 2 sides of the equation to be equal, then the factor
(x + a) = (x - 3) and by comparison
a = - 3
Let the value of the number be represented as x.
Then, write out an equation;
3x=2x+3 <--- Solve for x now
3x-2x=3
x=3
Therefore the number is 3.

Answer:
C
Step-by-step explanation:
She earns $3,567 and spends $2,895. That means that $2,895 is taken away from how much she earns each month. Subtraction is the correct operation, cancelling out choices B and D
$3,567 - $2,895
Now, you need to figure out the answer to the above problem. Choice C is your answer.
$3,567 - $2,895 = $672
