Answer:

The value of X in the equation 3X (-1) / 9Y equals 18 when Y equal 27 is 1458.33

Step-by-step explanation:

$\frac{3X - 1}{9 Y} = 18$ is a polinomial equation A

if the value of Y = 27

put this value of Y in the equation A

$\frac{3 X -1}{9 \times 27} = 18$

$\frac{3 X -1}{243} = 18$

243 will be taken to right hand side and as per rule will be multiplied by 18

$3X-1= 18\times 243\\$

$3X-1= 4374$

1 will be taken to right hand side and added as per rule

$3 X = 4374+1\\3X= 4375$

3 wil be taken on right hand side and divided as per rule

$X= \frac{4375}{3} \\X= 1458.33$

So the value of X if Y = 27 is 1458.33

Which choice is the solution to the inequality below?

Georgia [21]

<h3>hello!</h3>

In order to solve this inequality, we should divide both sides by 9:-

$\sf{9x < 72}$

Why 9? Because x is multiplied by 9, and we need to isolate x in order to find its value.

$\sf{x < 8}$

Hence, that's the solution to the inequality.

<em>It also means that the numbers less than 8 will satisfy the given inequality (make the inequality true)</em>

(Option C is correct :) )

Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I will comment and/or edit my answer :)

" A projectile is launched in the air according to the equation h(t)= -16t^2 + 125t + 5. At what time does the projectile land?"

Vlad1618 [11]

"according to the equation is a sloppy description, and announces that whoever said it or wrote it doesn't really have a clue to what the equation means or what it's good for.

h (t) is the HEIGHT of the projectile above the ground at any time 't'. When the projectile hits the ground, h (t) is zero. Write that ! Then you have a quadratic equation that you can easily solve for 't'.

If you were to move use the substitution method to solve the following system choose the new equation after the expression equiv

yanalaym [24]

Solve x+4y = 13 for x by subtracting 4y from both sides.

We end up with x = -4y+13.

Since x and -4y+13 are the same, we can replace every x in the first equation with -4y+13

2x-3y = -29

2( x ) - 3y = -29

2( -4y+13 ) - 3y = -29 ... x is replaced with -4y+13

The answer is choice B

Answer: $61.50

Step-by-step explanation:

To do this you need to first find 18% of 75 which is 13.5 or $13.50 and then subtract that from the original price being $75 and you get $61.50

HOPE THIS HELPS ^^
