To solve this, we need to use PEMDAS: Parentheses, exponents, multiplication, division, addition, subtraction

((4 x 8) + 10) x 3

Parentheses - multiplication

(32 + 10) x 3

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

A certain circle can be represented by the following equation. x^2+y^2+18x+14y+105=0 What is the center of the circle? What is t

Gre4nikov [31]

Answer:

See below.

Step-by-step explanation:

Recall the equation for a circle:

$(x-h)^2+(y-k)^2=r^2$ , where (h,k) is the center and r is the radius.

We need to turn the given equation into the above format. We do this by completing the square.

First, group them:

$(x^2+18x)+(y^2+14y)=-105$

For the first section, complete the square for $x^2+18x$ :

$x^2+18x+81-81$

$(x+9)^2-81$

Do the same for the second:

$y^2+14y$

$y^2+14y+49-49$

$(y+7)^2-49$

All together:

$((x+9)^2-81)+((y+7)^2-49)=-105$

$(x+9)^2+(y+7)^2-130=-105$

$(x+9)^2+(y+7)^2=25$

The center is (-9,-7).

The radius is $\sqrt{25}=5$
