Answer:

B. -3, 3, -3, 3...

Step-by-step explanation:

There's two types of sequences, arithmetic and geometric.

Arithmetic equations are sequences that increase or decrease by adding or subtracting the previous number.

For example, take a look at the following sequence:

2, 4, 6, 8, 10, 12, 14, 16, 18, 20...

Here, the numbers are increasing by +2. [adding]

So, this the sequence is arithmetic, since its adding.

Geometric sequences are sequences that increase or decrease by multiplying or dividing the previous number.

For example, take a look at the following sequence:

2, 4, 16, 32, 64, 128, 256, 512...

Here, the numbers are icnreasing by x2. [multiplying]

So, the sequence is geometric since its multiplying.

Based on this information, the correct answer is "B. -3, 3, -3, 3..." since its being multiplyed by -1.

Morgan is throwing a pizza party. She has 1 7/8 pounds of cheese available and she needs 1/5 pound of cheese to make each pizz

Karolina [17]

We have been given that Morgan is throwing a pizza party. She has 1 7/8 pounds of cheese available and she needs 1/5 pound of cheese to make each pizza. We are asked to find the number of full pizzas that Morgan can make with the amount of cheese she has.

To solve our given problem, we will divide total amount of cheese by amount of cheese used to make each pizza.

$\text{Number of pizzas}=1\frac{7}{8}\div \frac{1}{5}$

$\text{Number of pizzas}=\frac{15}{8}\div \frac{1}{5}$

Now we will convert our division problem into multiplication problem by flipping the 2nd fraction.

$\text{Number of pizzas}=\frac{15}{8}\times \frac{5}{1}$

$\text{Number of pizzas}=\frac{75}{8}$

$\text{Number of pizzas}=9\frac{3}{8}$

We are asked to find the number of full pizzas and we can see that Morgan can make 9 full and $\frac{3}{8}$ pizzas.

Since there are 9 full pizzas, therefore, Morgan can make 9 full pizzas with the amount of cheese she has.
