1. The Senior Class of Great Ridge High School and Ann Arbor High School are planning a trip to Six Flags Theme Park. Great Ridg
Zanzabum

Answer:

A)14v + 16b = 1152

10v + 13b = 925

B)Number of students in a van = 8

Number of students in each bus = 65

C) Elimination method was easier.

Step-by-step explanation:

Let v be the number of students in a van

Let b be number of students in a bus

A) We are told the first school can fill 14 vans and 16 buses with 1152 students

Thus;

14v + 16b = 1152 - - - - - (eq 1)

Also,we are told that the second school can fill 10 vans and 13 buses with 925 students.

Thus;

10v + 13b = 925 - - - - (eq 2)

B) To solve this we will use elimination method.

Multiply eq (1) by 5 and multiply eq (2) by 7 to give;

70v + 80b = 5760 - - - - eq(3)

70v + 91b = 6475 - - - - - eq(4)

Subtract eq(3) from eq(4) to give;

91b - 80b = 6475 - 5760

11b = 715

b = 715/11

b = 65

Put 65 for b in eq(3) to give;

70v + 80(65) = 5760

70v = 5760 - 80(65)

70v = 560

v = 560/70

v = 8

Number of students in a van = 8

Number of students in each bus = 65

C) Elimination method was used because in both equations, we had different digits attached and so it would have been more tedious to use substitution method or graphical method. Thus, elimination method was more easier.

What number must be added to the expression below to complete the<br> square?<br> x² - 18x
kiruha [24]

Answer:

\boxed {\boxed {\sf 81}}

Step-by-step explanation:

The standard form of a quadratic is:

ax^2+bx+c

To complete the square, the a (leading coefficient) must be 1 and there can only be terms with variables on one side.

The expression given:

x^2-18x

follows these rules. Next, we divide the b (linear coefficient) by 2, then square it. Basically:

(\frac{b}{2})^2

The b in the expression is -18.

(\frac{-18}{2})^2

(-9)^2= -9*-9= 81

This is the number that is added.
