If five slices of pizza costs 5.50 how much would two slices cost? ten slices? half a slice?
tensa zangetsu [6.8K]

Answer:

The first thing we must do for this case is to define variables.

We have then:

x: number of slices

y: total cost

We write the linear function that relates the variables.

We have then:

Then, we evaluate the number of slices to find the total cost.

-two slices cost:

We substitute x = 2 in the given equation:

Answer:

two slices = 2.2 $

-ten slices cost:

We substitute x = 10 in the given equation:

Answer:

ten slices = 11 $

-half a slice cost:

We substitute x = 1/2 in the given equation:

Answer:

half a slice = 0.55 $

Parallelograms don’t understand
djyliett [7]

Answer:-43 + 9x = 0

Step-by-step explanation:Simplifying

9x + -43 = 0

Reorder the terms:

-43 + 9x = 0

Solving

-43 + 9x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '43' to each side of the equation.

-43 + 43 + 9x = 0 + 43

Combine like terms: -43 + 43 = 0

0 + 9x = 0 + 43

9x = 0 + 43

Combine like terms: 0 + 43 = 43

9x = 43

Divide each side by '9'.

x = 4.777777778

Simplifying

x = 4.777777778

Transforme em π rad :<br>a)30°<br>b)40°<br>c)45°<br>d) 50°
Roman55 [17]

Answers:

a) \frac{1}{6} \pi rad

b) \frac{2}{9} \pi rad

c) \frac{1}{4} \pi rad

d) \frac{5}{18} \pi rad

Step-by-step explanation:

In this case we are dealing with angles, which can be expressed in degrees (\°) or radians (rad).

Now, before making the conversions we have to know the equivalence between degrees and radians:

180 \°=1 \pi rad

Taking this information into account, let's begin with the answers:

a) 30\° \frac{1 \pi rad}{180 \°}=\frac{1}{6} \pi rad

b) 40\° \frac{1 \pi rad}{180 \°}=\frac{2}{9} \pi rad

c) 40\° \frac{1 \pi rad}{180 \°}=\frac{1}{4} \pi rad

d) 50\° \frac{1 \pi rad}{180 \°}=\frac{5}{18} \pi rad
