Lets just say the number is equal to x.
-1(2x+3)=2*(-4x-3)
Distribute on both sides
-2x-3=-8x-6
Add 3 to both sides
-2x=-8x-6
Add 8x to boths sides
6x=-6
Divide Both Sides by -1
x=-1
The numbers is -1.

Step-by-step explanation:
The data plots represent the hours students study each week in two different classrooms.
The mean number of hours a student in Mr. Hart’s class studies is <em>4.6</em> hours.
The mean number of hours a student in Ms. Perry’s class studies is <em>2.8</em> hours.
A typical student in Mr. Hart’s class studies <em>More Than</em> a typical student in Ms. Perry’s class.

Hi there, first divide 24 by 80: 24÷80=30, Therefore, 24 is 30% of 80
The number of buckets is directly proportional to the area and the thickness of the wall and inversely proportional to the amount of paint. Mathematically, we can write:
n = k · (a · t) / p
where k is the proportionality constant which we do not know.
We can calculate k with the given data: 5 2-gallon buckets, area of 100 square feet and thickness 3 inches:
k = (n · p) / (<span>a · t)
= (5 </span>· 2) / (100 · 3) = 0.0333
Now that we know the constant, we can calculate the area that can be painted with 8 2-gallon buckets if the thickness is 6 inches:
a = (n · p) / (k<span> · t)
= (8 </span>· 2) / (0.0333 · 6)
= 80 ft²
Please, note that we made sure to have the exact same units of measurements than the previous case.
Therefore, the correct answer is an area of 80 ft².
