Answer:
just plug in the x value into the equation and put it in ur calculator
Answer: B. 12=9+3x
Step-by-step explanation:
A. It is an equation, but you can’t really do anything with it, let alone solve it.
C. 30+6 does not equal to 62, so definitely not.
D. 3x-4y is something, but there is no equa sign.
So, your andswer is B. 12=9+3x
Before we try to solve anything, let's convert our fractions into decimals, this so if we use a calculator (or writing on paper), it will be much easier to put it.
131 1/4 = 131.25 (divide 100 by the denominator to know each 1/x value).
12 1/2 = 12.50
The formula for the area of a rectangle is L x W, or Length x Width.
Since we are looking for our width, w, we need to divide by the length.
131.25 / 12.5 = 10.5.
Our width is 10 1/2 ft.
I hope this helps!
It's not too difficult!! your absolute value expression is already isolated, so now you have to set it up like this:
5v + 3 > -9
and
5v + 3 < 9 (opposite of original, flip inequality symbol)
this is because absolute value only tells you how many units away a number/expression is from 0 on a number line. it could go to the left, or the right--negative, or positive. so you have to allow for both equations
from there, just solve them like normal inequalities
5v + 3 > -9 ... subtract 3
5v > -12 ... divide by 5
v > - 12/5
5v + 3 < 9 ... subtract 3
5v < 6 ... divide by 5
v < 6/5
so, v must be greater than -12/5, and less than 6/5
Answer:
arc ≈ 25.13 feet
Step-by-step explanation:
arc length = circumference × fraction of circle
= 2 πr × 
← cancel 2π
= 6 × 
= 8π ≈ 25.13 feet
