Last Saturday, Jay spent 6 hours playing games, studying and talking with his friends. he spent 2/5 of the time playing games and 1/2 of the time studying. How many minutes did he spend talking with his friends?

Answers

Answer 1

Answer: (1 - (2/5 + 1/2)) x (6 x 60)
(1 - (4/10 + 5/10)) x 360
(10/10 - 9/10) x 360
1/10 x 360 = 36
so he spend 36 minutes talking with his friend

Answer 2

Answer:

Final answer:

Jay spent 36 minutes talking with his friends on Saturday after spending 2/5 of his time playing games and 1/2 of his time studying.

Explanation:

The total time Jay spent on all activities is 6 hours. He spent 2/5 of his time gaming, so that would be 0.4 * 6 hours = 2.4 hours, and he spent half of his time studying, that's 0.5 * 6 hours = 3 hours. To figure out how much time he spent talking with friends, we subtract the time spent gaming and studying from the total time. So, 6 hours – 2.4 hours – 3 hours = 0.6 hour. As there are 60 minutes in an hour, Jay spent 0.6 * 60 = 36 minutes talking with his friends.

9.64 rounded to the nearest tenth

Answers

Hello,

9.64 rounded to the nearest tenth is 9.6.

Have A Good Day.

Your answer would be 9.6

.6 is a six tenths.

To help you remember to round up or down remember this rhyme: 5 or more raise the score. 4 or less give it a rest.

9.64 is rounded to the nearest hundredth. To get to the nearest tenth you need to get rid of the four. Since it's less than 5, you just knock it away like it wasn't ever there. If it's 5 or above, you would have to round the number up. If you had to round up it'd be 9.7.

at a restaurant the ratio of kids meals sold to adults meal was 5:4. if there were 20 kids meals sold, what is the combined amount of kids and adults sold meals sold?

Answers

I would set up a proportion:

$(20)/(x)=(5)/(4)$

The proportion basically says, "if there are 5 kids meals for every 4 adult meals, that means 20 kids meals would mean x adult meals." Just cross multiply and then solve for x:

$(20)/(x)=(5)/(4)\n5x=80\nx=16$

That means there are 20 kids meals sold and 16 adult meals sold, so the result is:

36 meals in total.

$5x=20\ \ \ \ | divide\ by\ 5\n\nx=4\n\n5x+4x=9x=9*4=36\n\nCombine\ amount\ is\ 36.$

8x+4y=-20 and -4x-8y=-20 solve each system by substitution

Answers

8x + 4y = -20
4y = -20 - 8x
y = -5 -2x

-4x - 8y = -20
-4x - 8(-5-2x) = -20
-4x + 40 + 16x = -20
12x = -60
x = -5

8(-5) + 4y = -20
-40 + 4y = -20
4y = 20
y = 5
