Answer:

Step-by-step explanation:

You want to rewrite the equation

Ax +By=C A,B,C are integers

30(-3/2x) = 30(-2/5y-10/3)

-45x = -12y - 100

-45x + 12y = -100

Answer:

standard form is 45x -12y -100 = 0.

Step-by-step explanation:

Given the equation is -3/2x=-2/5y-10/3.

Finding common denominator, L.C.M.(2,5,3) = 30.

Multiplying both sides by 30.

30*(-3/2x) = 30*(-2/5y-10/3)

-45x = -12y -100

Moving all terms on left side, keeping right side equal to 0.

-45x +12y +100 = 0

Making x's coefficient positive by changing all signs.

45x -12y -100 = 0

Hence, standard form is 45x -12y -100 = 0.

Simplify: -|-15| please answer correctly i'll give brainliest and 5-star rating.

12345 [234]

Answer:

-15

Step-by-step explanation:

Definition of absolute value:

Distance from zero on a number line.

Imagine a number line with 0 in the middle of it. Now mark the number 3 on it. Also mark the opposite of 3, which is -3. What is the distance from zero to those 2 points? it's 3.

This is exactly like saying |3| = 3 and |-3| = 3

Even if the number inside absolute value is negative, it simplifies to the positive of the same number.

_______________________________

So let's talk about your problem.

-|-15|

> the absolute value simplifies to 15

-|-15| = - 15

So that ends up being your answer.

$-15$

[FIRST TO ANSWER GETS BRAINLIEST] Here is a rectangle ABCD. The length of the rectangle is increased by 10%. The width of the re

erastovalidia [21]

New length = 30x110% = 33cm
new width = 20x105% = 21cm

original perimeter = 30x2 + 20x2
= 60 + 40 = 100
new perimeter = 33x2 + 21x2
= 66 + 42 = 108

increase in perimeter = 108-100 = 8
percentage increase = 8/100 x 100% = 8%
