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

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
= - 4
= 4
f(x) =
= - 2( - 4 ) + 19 = 27
= 27
f(x) =
= - 2( 4 ) + 19 = 11
= 11
<em>( 4, 11 ) , ( - 4, 27 )</em>
Answer:
8x^2 - 26x + 33
Step-by-step explanation:
Add the expressions.
2x^2 - 13x + 12 + 6x^2 - 13x + 21 =
= 2x^2 + 6x^2 - 13x - 13x + 12 + 21
= 8x^2 - 26x + 33
Y = 3
Exp:
10 + 12y = 2y + 40
- 2y = - 2y
10 + 10y = 40
-10 -10
10y = 30
/ 10 / 10
y = 3
