45 cookies will serve 15 students.

You would multiply 15 by 2 that would give you 30, therefore you multiply 45 by 2 which will be 90.

Suppose an=3an-1 -5an-2 -4an-3. and a4= -7, a5=-36, a6=-85 , find a1 , a2, a3

maria [59]

Answer:

$a_1=4\\\\a_2=0\\\\a_3=3$

Explanation:

The equation is:

$a_n=3a_{n-1}-5a_{n-2}-4a_{n-3}$

and

$a_4=-7, a_5=-36, a_6=-85$

<u>1. Subsittute n = 6 into the equation:</u>

$a_6=3a_{5}-5a_{4}-4a_{3}$

Now subsititute the known values:

$-85=3(-36)-5(-7)-4a_{3}$

You can solve for $a_3$

$-85=-108+35-4a_{3}\\\\4a_3=12\\\\a_3=12/4\\\\a_3=3$

<u />

<u>2. Substitute n = 5 into the equation:</u>

$a_5=3a_{4}-5a_{3}-4a_{2}$

Substitute the known values and solve for $a_2$

$-36=3(-7)-5(3)-4a_{2}\\\\4a_2=-21-15+36=0\\\\a_2=0$

<u>3. Substitute n = 4 into the equation, subsitute the known values and solve for </u> $a_1$ <u />

$a_4=3a_{3}-5a_{2}-4a_{1}$

$-7=3(3)-5(0)-4a_{1}\\\\4a_1=9+7=16\\\\a_1=4$

Anthony eats 2 alices of a large 18 inch pizza. Lucy eats 4 lices of a 12 inch pizza. Both pizzas are cut into 8 slices. Lucy cl

Vlad [161]

Answer: Lucy ate more pizzas because he ate more inches of pizza than Anthony.

Step-by-step explanation:

Anthony eats 2 slices of a large 18 inch pizza. Total number of slice in the 18 inch pizza is 8

The size of one slice in inches would be total length of pizza / number of slices. It becomes

18 / 8 = 2.25 inches

Anthony ate 2 ×2.25 = 4.5 inches of pizza.

Lucy eats 4 slices of a 12 inch pizza.

Total number of slice in the 12inch pizza is 8

The size of one slice in inches would be total length of pizza / number of slices. It becomes

12 / 8 = 1.5 inches

Lucy ate 4 × 1.5 = 6 inches of pizza.

Lucy ate more pizzas because he ate more inches of pizza than Anthony.
