Answer:

Sierra studied 3 hours

William studied 2 hours

Step-by-step explanation:

jonah studied 6 hours.

He also studied 3 hours longer than sierra meanining sierra studied 3 hours less than 6 hours.

So, 6 hours minus 3 hours is equals to 3 hours.

With that being said, Sierra has studied 3 hours.

Sierra = 3 hours

The question then states that Jonah studied 3 times as many hours as William.

Reminder: Jonah studied 6 hours in total.

This means that jonahs' hours (6 hours) is equals to 3 times williams hours (3x)

6 hours= 3x                        

x= williams hours

we divide both sides by 3 to see what x is equals to

in other words, we divide Jonahs' hours to see what williams hours are

With that being said, William studied for 2 hours

2 hours = x

Completing the sqaure <br> x^2+14x+34
DiKsa [7]

Answer:

-7-√15

Step-by-step explanation:

First move the constant to the right hand side and change it's sign

x^2+14x=-34

Then add (14/2)^2 or 7^2 to both sides

x^2+14x+49=-34+49

Then factor the expression

(x+7)^2=-34+49

Then solve (x+7)^2=15

You should get:

x=-√15-7

or

x=√15-7

Please help me with this geometry question:((
Fudgin [204]

Answer:

x = 13

RQ = 160°

Step-by-step explanation:

Inscribed angles are half the intercepted arc angle.

5x + 15 = ½ (RQ)

RQ = 10x + 30

Arc angles add up to 360°.

10x + 30 + 9x + 17 + 6x − 12 = 360

25x + 35 = 360

25x = 325

x = 13

Therefore, RQ = 160°.

What is the percent of change from 35 to 62? round to the nearest percent.
Leona [35]

In order to change from 35 to 62, we have to add 27. So, the question becomes: which percentage of 35 is 27?

To answer this question, we set this simple equation

27 = 35\cdot\dfrac{x}{100}

And solving for x we have

x = \dfrac{2700}{35} \approx 77.14

So, if you change from 35 to 62, you have an increase of about 77%
