Answer:

Angle x = 120 degrees

Angle y = 60 degrees

Step-by-step explanation: Angle x has to be equivalent to the 120 degree angle that is already given since lines l and m are parallel as well as lines p and q. To find angle y, you must realize that angles x and y are supplementary angles, so their sum is 180 degrees. Since we now know that angle x is 120 degrees, you must subtract 120 from 180 in order to find the value of angle y: 180 - 120 = 60 degrees. I'm sure that there are other methods to figuring this question out, but this is how I did it.

In a college parking lot, the number of ordinary cars is larger than the number of sport utility vehicles by 77.3%. the differen

mezya [45]

Let x be the number of ordinary cars

Let y be the number of SUV's

The difference between the number of ordinary cars and the number of suvs is 17.

So x-y=17 ----> first equation

The number of ordinary cars is larger than the number of sport utility vehicles by 77.3%.

ordinary cars = SUV + 77.3% of SUV

x = y + 0.773y

x = 1.773y

Now we solve for y

We plug in x=1.773y in first equation

1.773y - y=17

0.773y = 17

y = 21.9922

Number of SUV's = 22

How many 1/8s are in 9 3/4<br><br><br> Pleaseeee help meee

Gnom [1K]

Answer:

Step-by-step explanation:

First we want 9 3/4 into an improper fraction.

(9 * 4) + 3 / 4 = 39 / 4

Then we want to change 39 / 4 into the same denominator as 1/8

39 / 4 * 2 = 78 / 8

And there is your answer, 78!

(hopefully this is correct, have a nice day!)

ryzh [129]

Answer:

$\dfrac{343}{71}$

Step-by-step explanation:

Given the equation

$(5x-y)^4+4y^3=2433$

Find the derivative:

$((5x-y)^4+4y^3)'=(2433)'\\ \\4(5x-y)^3\cdot (5x-y)'+4\cdot 3y^2\cdot y'=0\\ \\4(5x-y)^3\cdot (5-y')+12y^2y'=0$

Substitute

$x=-1\\ \\y=2,$

then

$4(5\cdot (-1)-2)^3\cdot (5-y')+12\cdot 2^2\cdot y'=0\\ \\4(-5-2)^3(5-y')+48y'=0\\ \\4\cdot (-7)^3\cdot (5-y')+48y'=0\\ \\-1,372(5-y')+48y'=0\\ \\-6,860+1,372y'+48y'=0\\ \\1,420y'=6,860\\ \\y'=\dfrac{6,860}{1,420}=\dfrac{686}{142}=\dfrac{343}{71}$
