$\frac{z}{2} + 5 = 11 \ / \ simplify \\ \\ \frac{z}{2} = 11 - 5 \ / \ subtract \ 5 \ from \ each \ side \\ \\ \frac{z}{2} = 6 \ / \ simplify \\ \\ x = 6 \times 2 \ / \ multiply \ each \ side \ by \ 2 \\ \\ z = 12 \ / \ simplify \\ \\$

So, your answer to this problem is z = 12.

1/2z + 5 = 11
(1/2z) + 5 = 11
z/2 +5 = 11
z/2 = 11 - 5
z/2 = 6
z = 6 x 2
z = 12

Solve the following problem then write your answer before the number.

Triss [41]

Answer:

1) Rizza's average speed is 27 km/h.

2) The distance between Barretto and Pampanga is 294 km.

3) Aaron's journey was 3.5 hours long.

Step-by-step explanation:

1) Time taken to cove the distance = 20 minutes

60 minutes = 1 hour

So that, 20 minutes = $\frac{20}{60}$ hours

= $\frac{1}{3}$ hours

Distance covered = 9 km

But,

speed = $\frac{distance covered}{time taken}$

Rizza's average speed = 9 ÷ $\frac{1}{3}$

= 9 x 3

= 27 km/h

Rizza's average speed is 27 km/h.

2) Time taken = 3.5 h

the car's average speed = 84 km/h

Distance between Barretto and Pampanga = average speed x time taken

= 84 km/h x 3.5 h

= 294 km

The distance between Baretto and Pampanga is 294 km.

3) The uniform speed implies that Aaron did not accelerate during his journey.

Distance covered = 210 km

uniform speed = 60 km/h

time taken = $\frac{distance covered}{speed}$

= $\frac{210}{60}$

= 3.5 hours

Aaron's journey was 3.5 hours long.

Ifinity stones what are they

WINSTONCH [101]

Answer:

infinity stones are from the mcu franchise (marvel universe) and they are gems that represent different aspects of existence. There are 6 of them and they represent the Mind, Power, Reality, Soul, Space, and Time. These gems posses a lot of power (a lot is an understatement) and in the wrong hands, they are deadly to the existence of humans. I won't go into the details of infinity war/endgame since that is technically spoiling.

On average, sloths spend 16.5 hours per day sleeping. what percent of the day do sloths spend sleeping? round your answer to the

Oliga [24]

Unknown if you wanted to be clever
on average means typically so there is data called "outliers"
Moreover it doesn't say what average percent of the day and it doesn't mention the planet, namely Earth..
there could be sloths on other planets and those other planets are likely to have different hours in the day.
