Answer:

1 hour and 5 minutes

Step-by-step explanation:

Between 4:22 pm and 3:17 pm, 1 hour has passed.

3:17 + 1 hour = 4:17

Between 4:17 pm and 4:22 pm, 5 minutes has passed.

4:17 + 5 minutes = 4:22

Therefore, Angela has studied for 1 hour and 5 minutes.

I hope this helps!

3/4x+5−1/2x=3 what is the value of x?
dimaraw [331]

Answer:

-1/8 is the answer

Step-by-step explanation:

1.) 1st we have to take 1/2x and make the bottom number 4. so we multiply by 2 and you should get 2/4.

2.) so now the equation should be 3/4x + 5 -2/4x = 3. now you take 3/4x and -2/4x and subtract them and you should get 1/4x.

3.) now the equation should look like 1/4x + 5 = 3. now we need to get all whole numbers to one side. so we will subtract 5 from 5 and that will cancel it out and we need to do that to both sides. so we will subtract 5 from 3 and you will get -2.

4.) now the equation should look like 1/4x = -2. now you put a 1 under the 2 to make it a fraction. it should look like 2/1 and then you are going to flip it because that is how you divide fractions. so now your equation should look like 1/4x = 1/2. now you multiply strait across both bottom and top. and you will get x = -1/8 and that is your answer.

hope this helped!

p.s it would be cool if you gave me brainliest.

stira [4]
X^2 - 8x-9=0
D = b^2- 4*a*c = 64- 4* (-9) = 64+36=100 =10^2
