Answer with Explanation:

Let total number of CD's = x

Then, number of CD kept by Julia $=\frac{C}{2}$

Number of CD's Ahmed have $=\frac{C}{2}+5$

Expressing the statement in terms of equation

Total number of CD's= Number of CD's possessed by Julia +Number of CD's Ahmed have

$x= \frac{C}{2}+\frac{C}{2}+5\\\\x=C+5$

So, In this situation, C+ 5 represent, total number of CD's.

Y_Kistochka [10]

R=5.4

4.2r-12.68=10
+12.68 +12.68
4.2r=22.68
4.2/4.2 22.68/4.2
22.68/4.2= 5.4

Hope this helps! Have a great day :)

Will give you BRAINLEST

____ [38]

Answer:

Both boxes have the same amount of work applied to them. The smaller box will get to the end first.

Step-by-step explanation:

For the 400 kg box, we can say,

force = 1 newton

force = mass*acceleration

1 = 400*acceleration

acceleration = 1/400 meters per second^2

acceleration = 0.0025 meters per second^2

Each second, the larger box's velocity is increasing by 0.0025 meters per second.

While the smaller box would have an acceleration of...

force = 1 newton

force = mass*acceleration

1 = 200*acceleration

acceleration = 1/200 meters per second^2

acceleration = 0.005 meters per second^2

Which is twice as much as the larger box.

Put simply: if the force applied is the same for the two boxes, then the smaller box will have larger acceleration. This is because more force is needed to push on the larger mass.

Because the smaller box has more acceleration, it will naturally travel faster compared to the larger box. Therefore, the smaller box reaches the goal line faster.

2k - 2j when j=4&k=6 replace the variable with the given amount and solve the problem

eimsori [14]

Answer:

Step-by-step explanation:

first, plug in 6 for k. (it doesn't matter which value you plug in first; you can start with j or k, but i'm just starting with k since that is the variable that comes first in the expression)

2k - 2j => 2(6) - 2j

then plug in 4 for j.

2(6) - 2j => 2(6) - 2(4)

now your expression is 2(6) - 2(4). simplify by multiplying 2(6) and then -2(4) (again, it doesn't matter which one you multiply first, as long as you make sure that the minus sign between 2(6) and 2(4) gets attached to the 2 in 2(4).)

2(6) - 2(4) => 12 - 2(4)

12 - 2(4) => 12 - 8

subtract 8 from 12.

12 - 8 = 4

your answer is 4, therefore when j = 4 and k = 6, 2k - 2j = 4.

i hope this helps! have a nice day <3
