5) Last week a Pizza Hut sold 36 cheese pizzas, 64 pepperoni pizzas, and 20 veggie pizzas. Based on these data, which number is

Goshia [24]

Answer:

$P(Cheese) = 0.30$

Step-by-step explanation:

Given

$Cheese = 36$

$Pepperoni = 64$

$Veggie = 20$

Required

$P(Cheese)$

This is calculated as:

$P(Cheese) = \frac{Cheese}{Total}$

$P(Cheese) = \frac{36}{36+64+20}$

$P(Cheese) = \frac{36}{120}\\$

$P(Cheese) = 0.30$

If EFGH is a parallelogram, what is the value of x?

Leokris [45]

To be a parallogram the 2 angles shown need to equal 180 degrees

so we have: 34 + (4x-2) = 180

now we can solve for x

34 + 4x -2 = 180

simplify the left side by subtracting 2 from 34

32+4x =180

subtract 32 from each side:

4x = 148

divide both sides by 4 to get x

x = 148 / 4

x = 37

The answer is B

2x + 12 = -2(4-2x) X=10 X=-10 X=-5 X=5

Greeley [361]

Answer:

$\boxed{x = 10}$

Step-by-step explanation:

$= > 2x + 12 = - 2(4 - 2x) \\ \\ = > 2x + 12 = (( - 2) \times 4) - (( - 2) \times 2x) \\ \\ = > 2x + 12 = - 8 - ( - 4x) \\ \\ = > 2x + 12 = - 8 + 4x \\ \\ = > 2x - 4x + 12 = - 8 \\ \\ = > - 2x + 12 = - 8 \\ \\ = > - 2x = - 8 - 12 \\ \\ = > \cancel{-} 2x = \cancel{- }20 \\ \\ = > 2x = 20 \\ \\ = > x = \frac{20}{2} \\ \\ = > x = 10$
