Answer:

Elsa - 17 orders

Deon - 22 orders

Carlos - 68 orders

Step-by-step explanation:

You need to set variables and create system of equations first.

Elsa=  e

Deon= d

Carlos = c

e+d+c=107

d=e+5

c=4e

Now you plug in the values into the equation x+y+z=116

e+(e+5)+(4e)=107

6e+5=107

6e=102

e=17

You plug in the value of x into the other equations.

e = 17

d= 17+5=22

c=4*(17)=68

Rearrange so it corresponds with days...

Elsa - 17 orders

Deon - 22 orders

Carlos - 68 orders

P and Q are points on the line 3y - 4x = 12
Lorico [155]

Answer:

Step-by-step explanation:

Since the coordinates of P are (0, 1), this makes P the y-intercept of that line. The y-intercept exists where x = 0. And in the coordinate (0, 1), x does in fact equal 0.

Since the one coordinate given in Q is (?, 0), this means that Q is the x-intercept of the line. The x-intercept exists where y = 0. And in the coordinate (?, 0), y does in fact equal 0. So in order to solve for the x coordinate of Q, we plug in a 0 for y and solve for x:

3(0) - 4x = 12 and

-4x = 12 so

x = -3
