David works six more hours per week than Xavier. If Xavier works 32 hours a week, what is the total hours the two work in a
Finger [1]

We are required to find the total hours David and Xavier works in a week

The total hours David and Xavier works in a week is 70 hours

let

number of hours Xavier works = 32 hours

number of hours David works = (6 + 32) hours

= 38 hours

<em>Total number of hours David and Xavier works in a week = number of hours Xavier works + number of hours David works</em>

= 32 hours + 38 hours

= 70 hours

Therefore, the total hours David and Xavier works in a week is 70 hours

Svetradugi [14.3K]

Answer:

<em>Answer: a = - 12</em>

Step-by-step explanation:

We have here two equations, one 18x + 12y = 36, the other ax - 8y = - 24;

Now if we were to consider making these two equations have a common y co - efficient, we would multiply the top equation by 2, the bottom consecutively by - 3. This would make a standard 24y ;

2 * ( 18x + 12y = 36 ),     ⇒       36x + 24y = 72

+ - 3 * (  ax - 8y = - 24 )            + - 3ax + 24y = 72

As you can see, all terms are equivalent, besides that of the co - efficient of x. Knowing that, it would be ax must be multiplied by - 3 to receive 36x, as the bottom equation is multiplied by - 3, where all terms are equivalent to the top terms;

- 3 * ax ⇒ 36x, - 3 * - 12x = 36x,

The hanger image represents a balanced equation (look at picture)
nekit [7.7K]

Answer:

A) 27 = b + 9

b=18

Step-by-step explanation:

When given a balanced scale (represented by a hanger in this image), the sum of the values on one side equals the value on the other side. Thus, the equation that this hanger represents is the following:

27 = b + 9

Use inverse operations to solve this equation,

27 = b + 9

-9

18 = b

Maya wrote the following matrix equation to represent a system of equations:
Ne4ueva [31]
I am somehow confused with the given matrix. Because usually, when the system of equations is given as:

ax + by = c
dx + ey = f

the matrix would be written in this manner:

\left[\begin{array}{ccc}a&b&c\\d&e&f\end{array}\right]

Let me just assume that the arrangement of the given corresponds to this system of equations:

4x + 8y = 0
2x + 5y = 6

So you write it as 

\left[\begin{array}{ccc}4&8&0\\2&5&6\end{array}\right]

In order to solve this, the matrix should look like this where x and y are the answers

\left[\begin{array}{ccc}1&0&x\\0&1&y\end{array}\right]


So, the first thing to do is apply this pattern: Row 2 = Row 1 - 2*Row 2. The result will be

\left[\begin{array}{ccc}4&8&0\\0&-2&-12\end{array}\right]

Next, Row 1 = (Row 1/4) + R2:

\left[\begin{array}{ccc}1&0&-12\\0&-2&-12\end{array}\right]

Lastly, Row 2 = Row 2 / -2:

\left[\begin{array}{ccc}1&0&-12\\0&1&6\end{array}\right]

Thus, the answer is x=-12 and y=6.
