Twice the sum of a number and 3 is the same as 24 less than 7 times the number
kakasveta [241]
2(x+3)=7x-24
2x+6=7x-24
(move 7x to the left by subtracting from both sides, and move the 6 to the right by subtracting from both sides)
-5x=-30
(divide -5 from both sides to get x by itself, and because the 30 and 5 are both negative, two negatives make a positive)
x=6

Coco needs 150mg of a medication that comes in tablets labelled 100mg each. How many tablets will you give her?
shtirl [24]

Answer:

1.5

Step-by-step explanation:

If 1 tablet is 100mg, and you need 150mg, we set up this equation:

Let x be the number of tablets Coco needs.

x = 150/100

x = 1.5

Therefore, you need 1.5 tablets for the medication.

There are 40 students at bail high who plat stringed instruments of these 1/4 play viola 1/5 play cello and the rest play violin
Ilia_Sergeevich [38]

Answer:

I'm not to sure but I think it's 39 11/20

Step-by-step explanation:

1/5 + 1/4 you have to get a common denominator which would be 20 and then you add the numerators to get 9. Then you would subtract 40 from 9/20 and have to get the common denominator again which would be 800/20 - 9/20 which is 751/20 simplified to 39 55/100 simplified even more to 39 11/20. I haven't done fractions for a while so it might be wrong. I hope I helped!
