X = oranges / y = apples

x - 2 = 2y and 0.5x - 0.5y = 4

x - 2 = 2y
   +2        +2
x = 2y + 2

0.5x - 0.5y = 4
2(0.5x - 0.5y = 4)
x - y = 8

Substitute 

(x) - y = 8
(2y + 2) - y = 8
3y + 2 = 8
     - 2       -2
3y = 6
y = 2

Substitute again

x = 2y + 2
x = 2(2) + 2
x = 4 + 2
x = 6

Hope this helps!

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.

A pair of shoes usually sells for $61. If the shoes are 40% off, and sales tax is 5%, what is the total price of the shoes, incl
lyudmila [28]
Since sale is 40% so the price is 60%

61*(60%) = 36.6

the tax is 5%

so the price after tax is: 36.6 * (1 +5%) = $38.43
