Lashonda, Pablo, and Hong served a total of 143 orders Monday at the school cafeteria. Pablo served 4 times as many orders as Ho
horsena [70]

Answer:

Hong = 25

Pablo = 100

Lashonda = 18

Step-by-step explanation:

Let Hong's order be x , since Pablo served 4 times as many as Hong , then Pablo's order is 4x , also , since Lashonda served 7 fewer than Hong , it means Lashonda's order is x - 7 . combining all

Hong's orders = x

Pablo's order = 4x

Lashonda's order = x - 7

Total order = 143

Then

x + 4x + x - 7 = 143

6x - 7 = 143

6x = 143 + 7

6x = 150

x = 25

Therefore :

Hong served 25 orders

Pablo served 24x 4 orders = 100 orders

Lashonda served 25 - 7 orders = 18 orders

What are the ordered pairs of the solutions for this system of equations?
Scorpion4ik [409]

Answer:

<em>( 4, 11 ) , ( - 4, 27 ) </em>

Step-by-step explanation:

f(x) = x² - 2x + 3

f(x) = - 2x + 19

x² - 2x + 3 = - 2x + 19

x² - 16 = 0

( x + 4 )( x - 4 ) = 0

x_{1} = - 4

x_{2} = 4

f(x) = y_{1} = - 2( - 4 ) + 19 = 27

y_{1} = 27

f(x) = y_{2} = - 2( 4 ) + 19 = 11

y_{2} = 11

<em>( 4, 11 ) , ( - 4, 27 )</em>
