Emily practices piano for 2/3 of an hour on Monday and 1/2 hour on Wednesdays. How many hours does Emily spend practicing piano

Sergeu [11.5K]

Answer:

50 minutes

Step-by-step explanation:

Given:

$\bullet \ \ \text{Monday:} \ \dfrac{2}{3} \times \text{Hour}\\\\\bullet \ \text{Wednesday:} \ \dfrac{1}{2} \times \text{Hour}$

Since Emily only practiced on Monday and Wednesday, the sum of time on both days is the time Emily practiced on the piano for a week.

$\implies \text{Monday + Wednesday = Total time practiced on piano for a week}$

<u>Substitute the times in the equation</u>

$\implies (\dfrac{2}{3} \times \text{Hour}) + (\dfrac{1}{2} \times \text{Hour}) = \text{Total time practiced on piano for a week}$

<u>Simplify the equation</u>

$\implies (\dfrac{2}{3} \times 60 \ \text{minutes}) + (\dfrac{1}{2} \times 60 \ \text{minutes}) = \text{Total time practiced on piano for a week}$

$\implies (20 \ \text{minutes}) + (30 \ \text{minutes}) = \text{Total time practiced on piano for a week}$

$\implies \boxed{50 \ \text{minutes} = \text{Total time practiced on piano for a week}}$

Answer:

1. x =8

2. x=9

Step-by-step explanation:

Since these figures are parallelograms, the opposite sides are equal.

1. 6 = 2x-10

Add 10 to each side

6+10 = 2x-10+10

16 = 2x

Divide each side by 2

16/2 = 2x/2

8 =x

2. x+14 =23

Subtract 14 from each side

x+14-14 = 23-14

x = 9
