Answer:
Summary. If the equation ends with a false statement (ex: 0=3) then you know that there's no solution. If the equation ends with a true statement (ex: 2=2) then you know that there's infinitely many solutions or all real numbers
Step-by-step explanation:
-3(2b-2a)
multiply -3 with 2b and -2a
-6b+6a
ANSWER: -6b+2a
Number of students in Math136 = 480
We are given that the number of students in Math136 is 20% more than the number of students in Math123. Let the number of students in Math123 be x. So we can set up the equation as:
Number of students in Math136 = 20% more than number of students in Math123
Number of students in Math136 = 20% more than x
480 = 20% more than x
480 = 20% of x + x
480 = 0.20x + x
480 = 1.20(x)
x = 480/1.20 = 400
This means, there are 400 students in Math123.
A point is an exact position or location on a plane surface. It is important to understand that a point is not a thing, but a place. We indicate the position of a point by placing a dot with a pencil. This dot may have a diameter of, say, 0.2mm, but a point has no size. No matter how far you zoomed in, it would still have no width. Since a point is a place, not a thing, it has no dimensions. Points are usually named by using an upper-case single letter. Usually represented by a dot.
Answer:
<em>1 : 2</em>
Step-by-step explanation:
<u>First situation</u>
sides of triangle:-
a=x, b=2x, c=3x
then perimeter = a+b+c
perimeter = x + 2x + 3x
<em>Perimeter = 6x</em>
<u>Second situation(sides are doubled)</u>
sides of triangle:-
a=2x, b=4x, c=6x
then perimeter = a+b+c
perimeter = 2x + 4x + 6x
<em>Perimeter = 12x</em>
<u>Ratio of first situation to second </u>
Perimeter of first situation : Perimeter of second situation
6x : 12x
<em>1 : 2</em>
