First you combine like terms which are 4b and -15b which turn into -11b and then you combine like terms again which are -7 and +3 which gets you to -4. So your final answer is -11b-4

find the elasped time from 10:11 to 5:34 pls show your work . A) 5hrs and 37mins , B) 4hrs , C) 5h 23mins , D) 4hr 37mins
Bingel [31]
The question as you wrote it doesn't fit the answers. However, one of the answers fits if you meant
"elapsed time from 5:34 to 10:11".

There are many ways to do this. Try first taking the time from 5:34 to 6:11, and after that finding the time from 6:11 to to 10:11.

In a way, 6:00 is the same thing as 5:60. Add 11 to that and you can see that 6:11 is the same as 5:71. Now that you have an easy way to find the time from 5:34 to 6:11.
6:11 - 5:34 isn't easy.
But 5:71 - 5:34 is quite easy. 71 - 34 is 37.

So, from 5:34 to 6:11 there are 37 minutes.

Now the easy part, finding the time from 6:11 to 10:11. Since the minutes are the same, just subtract the hours. 10 - 6 = 4 hours.

Now you have the hours and minutes, which number 4 hours and 37 minutes.

An account earns simple interest $600 at 5% for 2 years find the interest earned
iVinArrow [24]

Answer:

so your answer would be 60$

Step-by-step explanation:

I = P * r * t

Here, P = $600

r = 0.05 (decimal value for 5%)

t = 2 years

Part a)

The interest earned will be:

I = P * r * t

I = 600 * 0.05 * 2

I = $60  

Part b)  

The balance in the account will be $600 plus the interest earned or:

$600 + 60 = $660

Please help ASAP 40 PTS
umka21 [38]

Answer:

70

Step-by-step explanation:

The angle not marked in the top triangle is 40 degrees since it is an isosceles triangle.  That makes the angle opposite it in the other triangle 40 degrees since they are vertical angles and vertical angles are equal.

The bottom triangle has 3 angles that sum to 180 degrees,  The other angle not marked is also y since it is an isosceles triangle.

40 + y +y = 180

Subtract 40 from each side and combine like terms

40-40 +2y = 180-40

2y = 140

Divide by 2

2y/2 = 140/2

y = 70

Use the LCD to rewrite 34, 58, and 110 with the same denominator pls help
galben [10]

Answer: 30/40, 25/40, 4/40

Step-by-step explanation: Using the Least Common Denominator, I looked at each multiple of each number to determine 40 as the least common denominator, and since we did 4 x 10 to get 40 in the first one, we do 3 x 10 in the first one as well making it 30/40. The second one we did 8 x 5 to get 40, making the numerator (top number) the product of 5 x 5 which is 25 making it 25/40. For the last one, I used 10 x 4 to get 40 meaning I would have to do 1 x 4 to get the numerator (top number) making it 4/40
