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

Malik is standing outside in the sun. Malik is 72 inches tall, and his shadow is 60

anastassius [24]

Jeremy's height is 67.2 inches

The diagram below represents situation

<h3>Proportion</h3>

Proportion says that two ratios (or fractions) are equal. This a mathematical comparison between numbers.

Therefore, let's establish the proportion in this situation

Malik height / Malik shadow = Jeremy height / Jeremy shadow

Therefore,

72 / 60 = x / 56

cross multiply

72 × 56 = 60x

60x = 4032

divide both sides by 60

x = 4032 / 60

x = 67.2

Therefore, Jeremy's height is 67.2 inches

Answer:

34% = 272 students

100% = 272/34%

= 800 students

Step-by-step explanation:

to check whether the answer is correct

= 34% × 800

= 272 students
