Find the value of X and the missing angle

Mathematics
2 answers:
GuDViN [60]3 years ago

Answer:

x = 10

missing angle = 83°

Step-by-step explanation:

These are supplementary angles meaning they have a sum of 180°.

8x + 3 + 97 = 180

8x + 100 = 180

8x + 100 - 100 = 180 - 100

8x = 80

x = 10

Substitute the value for the variable.

8(10) + 3

80 + 3

83

PLEASE HELP!!!!! What is the value of x in the matrix equation below?
Brums [2.3K]

The given matrix equation is,

1.5\left[\begin{array}{cc}x&6\\8&4\end{array}\right] +y\left[\begin{array}{cc}1&4\\3&2\end{array}\right] =\left[\begin{array}{cc}z&z\\6z&2\end{array}\right].

Multiplying the matrices with the scalars, the given equation becomes,

\left[\begin{array}{cc}1.5x&9\\12&6\end{array}\right] +\left[\begin{array}{cc}y&4y\\3y&2y\end{array}\right] =\left[\begin{array}{cc}z&z\\6z&2\end{array}\right]  \\

Adding the matrices,

\left[\begin{array}{cc}1.5x+y&9+4y\\12+3y&6+2y\end{array}\right]  =\left[\begin{array}{cc}z&z\\6z&2\end{array}\right]  \\

Matrix equality gives,

1.5x+y=z\\ 9+4y=z\\ 12+3y=6z\\ 6+2y=2

Solving the equations together,

y=-2\\ 3y-1.5x=9\\ -1.5x=9+6\\ x=-10

We can see that the equations are not consistent.

There is no solution.

Owners of 800 homes in a subdivision list their houses, on average, every eight years. If a sales associate farms that neighborh
Gekata [30.6K]

Answer:

20 homes

Step-by-step explanation:

Given that :

Total number of homes = 800

Average years at which homes are listed = 8 years

To obtain the annual home listing = total number of Homes / average years

Annual home listing = 800 / 8

Annual home listing = 100 homes

If 20% of the homes are listed on the year in question :

20% of 100 homes

0.2 * 100

= 20 homes

20 homes can be listed that year

What is the value of X in 1.2÷0.3= X÷0.4
sashaice [31]

1.2 \div .3 = 4
4 = x \div .4
multiply both sides by .4 to isolate the x variable.

4 \times .4 = x

x = 1.6
