Thats a trick question, but I know the answer. You are supposed to divide 20/30. but that doesn't connect with the number. So we move on to 200/30. You multiply 30 by how many will it take to get 200. The answer would be 6.666666666667(hope this will help)

V^2 = u^2 + 2as

make S the subject

Answers

$V^2=u^2+2as\n\n 2as=V^2-u^2\n\n s=(V^2-u^2)/(2a)$

Hey!
So if you are solving for S, then follow these steps!
First you wanna subtract u^2 from both sides because that's the easiest way to go first.
V^2 - u^2 = 2as
Now you want to get s alone, but 2a is multiplied to it so you want to do the opposite which is dividing.
(V^2 - u^2)/2a = s
There's your answer!
Hope this helps!

How to solve 3+5 (c+3)=-17

Answers

3 + 5(c + 3) = -17

First, subtract 3 from both sides. / Your problem should look like: $5(c + 3) = -17 - 3$
Second, simplify -17 - 3 to get -20. / Your problem should look like: $5(c + 3) = -20$
Third, divide both sides by 5. / Your problem should look like: $c + 3 = -(20)/(5)$
Fourth, simplify $(20)/(5)$ to 4. / Your problem should look like: $c + 3 = -4$
Fifth, subtract 3 from both sides. / Your problem should look like: $c = -4 - 3$
Sixth, simplify -4 - 3 to get -7. / Your problem should look like: $c = -7$

Answer: c = -7

3+5(c+3)=−17

3+(5)(c)+(5)(3)=−17(Distribute)

3+5c+15=−17

(5c)+(3+15)=−17(Combine Like Terms)

5c+18=−17

Subtract 18 from both sides.

5c+18−18=−17−18

5c=−35

Divide both sides by 5.

5c/5=−35/5

c=−7

Terrence and Lee were selling magazines for a charity. In the first week, Terrance sold 30% more than Lee. In the second week, Terrance sold 12 magazines, but Lee did not sell any. If Terrance sold 50% more than Lee by the end of the second week, how many magazines did Lee sell?Choose any model to solve the problem. Show your work to justify your answer.

Answers

Lee sold 60 magazine

Step-by-step explanation:

Terrence and Lee were selling magazines for a charity

In the first week, Terrance sold 30% more than Lee
In the second week, Terrance sold 12 magazines, but Lee did not sell any
Terrance sold 50% more than Lee by the end of the second week

We need to find how many magazines Lee sold

Assume that Lee sold x magazines

∵ Terrance sold 30% more than Lee in the first week

∵ Lee sold x magazines in the first week

- Find 30% of x and add it to x to find how many magazines

Terrance sold

∵ Terrance sold = 30% × x + x

∴ Terrance sold = $(30)/(100)$ × x + x = 0.3 x + x

∴ Terrance sold = 1.3 x magazines in the first week

∵ Terrance sold 12 magazines in the second week

- Add 1.3 x to 12 to find the number of magazines that Terrence

sold in the two weeks

∴ Terrence sold 1.3 x + 12 magazines in the two weeks

∵ Lee did not sell any in the next week

∴ Lee sold x magazines in the two weeks

∵ Terrance sold 50% more than Lee by the end of the 2nd week

- Equate 1.3 x + 12 by the sum of x and 50% of x

∴ 1.3 x + 12 = 50% × x + x

∵ 50% × x = $(50)/(100)$ × x = 0.5 x

∴ 1.3 x + 12 = 0.5 x + x

- Add the like terms in the right hand side

∴ 1.3 x + 12 = 1.5 x

- Subtract 1.3 x from both sides

∴ 12 = 0.2 x

- Divide both sides by 0.2

∴ 60 = x

Lee sold 60 magazine
