Answer:

20

Step-by-step explanation:

Substitute x in y = 4x for 5. So now the equations stands as y = (4)(5). 4 times 5 equals 20

Answer:

500 boxes

Step-by-step explanation:

<em>hey there,</em>

<em />

< Since "p" stands for profits, change "p" to 0 (since the question says 0 profits).

Here is how your equation would look like:

0 = -n^2 + 300n + 100000

Pretend like "n" is "x" since that is the variable we are trying to find here.

Solve for "n". Move all terms to the left side and set equal to zero. Then set each factor equal to zero.

"n" actually ends up equaling 500, -200.

Obviously, negative can't be the answer because you can't have a negative amount of boxes. So 500 boxes would be your answer. 200 CAN'T be your answer <em>either </em>because it is a negative!! >

Answer:

37.5

50+160=210.

210 is a 31.25% increase from 160

Multiply 120 by 1.3125 to get 157.5

subtract 120 from 157.5 to get a 37.5km increase or a 31.25% increase :)

What is x? where would i find it?는 무엇이고 내가 그것을 어떻게 찾을까?​
kvv77 [185]

If you are implying that the triangles are similar, then the short and long legs are in proportion:

3\div 2 = x\div 8

Solving for x, you have

x = \dfrac{8\cdot 3}{2} = 12
