Answer:
m = 0
Step-by-step explanation:
The denominator of the rational expression cannot be zero as this would make the rational expression undefined. Equating the denominator to zero and solving gives the value that m cannot be.
4m² = 0 ⇒ m² = 0 ⇒ m = 0 ← excluded value
y=4/3-x/6
Step-by-step explanation:
6y/6+x/6=8/6
y+x/6=4/3
-x/6 -x/6
y=4/3-x/6
X = 6
11-3x=-7
Subtract 11 from both sides.
-3x = -18
Divide -3 on both sides.
X = 6
Petra can make 8 costumes with 12 yards of fabric
<h3><u>Solution:</u></h3>
Given that Petra was given 12 yards of fabric to make costumes for the school play
Each costume requires
yards
<em><u>To find: number of costume Petra can make</u></em>
The number of costume Petra can make is calculated by dividing the total fabric she has by fabric needed for one costume

Total fabric she has = 12 yards
Fabric needed for 1 costume =
yards
Therefore,

Thus petra can make 8 costumes with 12 yards of fabric
The mean of the number set is the average of the numbers
To find the average of the number set the numbers are to be added together and divided by the total amount of numbers in the set
