A group of friends ordered two pizzas, one with pepperoni and one with mushrooms and green peppers. A plain pizza costs 9 dollar

Xelga [282]

1 pizza = 9 dollars

1 topping = 1 dollar

1. Let's gather the information

2 Pizzas

One pizza is a pepperoni

The other is a mushroom and green pepper

2. Make an equation for the question

x9 + y1 = ?

x = number of pizzas

y = number of toppings

3. Multiply x and y by the number given

2 x 9 + 3 x 1 = ?

2 x 9 + 3 x 1 = 21

Which means, the two pizzas had costed 21 dollars.

Answer:

Step-by-step explanation:

a). $\frac{5\pm\sqrt{-4}}{3}$ = $\frac{5}{3}\pm \frac{\sqrt{-4}}{3}$

= $\frac{5}{3}\pm\frac{2\sqrt{(-1)} }{3}$

= $\frac{5}{3}\pm\frac{2i}{3}$ [Since, i = $\sqrt{(-1)}$ ]

b). $\frac{10\pm\sqrt{-16}}{2}$ = $\frac{10}{2}\pm \frac{\sqrt{-16}}{2}$

= $5\pm \frac{4\sqrt{-1}}{2}$

= 5 ± 2i [Since, i = $\sqrt{(-1)}$ ]

c). $\frac{-3\pm \sqrt{-144}}{6}$ = $-\frac{3}{6}\pm \frac{\sqrt{-144}}{6}$

= $-\frac{3}{6}\pm \frac{12\sqrt{-1}}{6}$

= $-\frac{1}{2}\pm 2\sqrt{-1}$

= $-\frac{1}{2}\pm 2i$ [Since, i = $\sqrt{(-1)}$ ]

The difference between the square roots of a number is 30. what is the answer?

Sveta_85 [38]

Since 30 is not a square root you would use the closest square roots √25 and √36 which makes your answer 5 and 6
