Answer:
The numbers are -3 and 18 .
Step-by-step explanation:
Let us assume that first number be x.
Let us assume that the second number be y.
As given
A first number plus twice a second number is 12 .
Than the equation becomes
x + 2y = 12
As given
Twice the first number plus the second totals 33.
2x + y = 33
Than the two equations are
x + 2y = 12
2x + y = 33
Multiply x + 2y = 12 by 2 and subtracted from 2x + y = 33
2x - 2x + y - 4y = 33 - 24
-3y = 9
y = - 3
Put in the equation x + 2y = 12
x + 2 ×-3 = 12
x - 6 = 12
x = 12 + 6
x = 18
Therefore the numbers are -3 and 18 .

<em><u>Fractions</u></em><em><u> are integers that have both a numerator and a denominator. </u></em>They are represented as;
Where:

To solve the above question, we would be applying the operations of the addition of fractions.
It will take both of them hours if they worked together.
From the question,
Nyesha takes 50 hours a week to render services to her customers.
Shantese takes 60 hours a week to do the same amount of work.
Let us represent the number of hours it will take them both to decorate the room working together as "T"
Hence,
1/T = 1/50 + 1/60
Lowest Common Denominator for (50, 60 ) = 300
Hence,
1/T = 6 + 5 / 300
1/T = 11/300
Find the reciprocal of both sides
T = 300/11 hours
T = <u>hours</u>
Therefore, it will take them both of them hours in they both work together.
