{a}^{2}  +  {b}^{2}  =  {c}^{2}  \\  {9}^{2}  +  {9}^{2}  =  {c}^{2}  \\  {81} + 81 =  {c}^{2}  \\ 162 =  {c}^{2}  \\  \sqrt{162}  =  \sqrt{ {c}^{2} }  \\ 12.73 = c
the length of the diagonal is 12.73

How many solutions does the system of equations shown below have?
rjkz [21]

Answer:

one solution with a y value of 5

Step-by-step explanation:

/| x+y-4 = 0| x-y-6 = 0

We try to solve the equation: x+y-4 = 0

x+y-4 = 0 // - x-4

y = -(x-4)

y = 4-x

We insert the solution into one of the initial equations of our system of equations

We get a system of equations:

/| x+x-6-4 = 0| y = 4-x

2*x-10 = 0 // + 10

2*x = 10 // : 2

x = 10/2

x = 5

We insert the solution into one of the initial equations of our system of equations

For y = 4-x:  

y = 4-5

y = -1

We get a system of equations:

/| y = -1| x = 5

Divide £50 in the ratio of 1:4
NikAS [45]
Answer=10:40


Explanation:

Don’t know how to type the symbol in font of the 50 so I will substitute

So 1:4
Add it up
1+4=5

So 5 total units
$50=5
Divided by 5
$10=1 units

So 1:4=10:10 times 4=10:40
