If y varies directly as x and y-21 when x<br> is 7, find x when y = -5.
klasskru [66]

Step-by-step explanation:

Since, y varies directly as x:

\therefore \: y = kx..(1) \\ (k = constant \: of \: proportionality) \\ at \: y = 21 \: and \: x = 7 \\ 21 = k \times 7 \\ k =  \frac{21}{7}  = 3 \\ plugging \: k = 3 \: in \: equation \: (1) \\ y = 3x..(2) \\ plugging \:  \: y =  - 5  \: in \: (2)\\  - 5 = 3x \\ x =  \frac{ - 5}{3}  \\   \:  \:  \:  \:  \:  \: \huge \red{ \boxed{x =  -  \frac{5}{3} }}

Jen ran 3/4 mile in 18 minutes at 9 am and 2 1/4 miles in 27 minutes at 6 pm. Is this proportional or non proportional?
VMariaS [17]

Answer:

It's non-proportional

Step-by-step explanation:

You could tell every 1/4 mile is 6 minutes, so every other number should be a multiple of 6 if it is a multiple of 1/4. 27 is not a multiple of 6.

Rearrange your equation to isolate a:(a+b/c)(d-e)=f
sukhopar [10]
To rearrange the equation given, we need to take note the rules in adding, subtracting, multiplying and dividing terms. We rearrange the equation as follows:

<span>((a+b/c)(d-e)=f) 1/(d-e)

</span>(a+b/c = f/(d-e))c

a+b = fc/(d-e)

a = [fc/(d-e)] - b

Hope this answers the question.

Answer:

  x = 8

Step-by-step explanation:

The marked angles are <em>alternate interior angles</em>, so are congruent.

  8x -4 = 60

  8x = 64 . . . . . . . . . . add 4 to both sides

  x = 64/8 = 8 . . . . . . divide both sides by 8

The value of x is 8.
