Multiplying both sides of a rational equation by a variable expression introduces the possibility of extraneous solutions. Therefore, we must check the solutions against the set of restrictions. If a solution is a restriction, then it is not part of the domain and is extraneous.
C or d i think is the correct answer
3, 4, 5, 6 and 7
Q 1= (3+4)/2=3.5
Q 2= (4+5)/2=4.5
Q 3=(5+6)/2=5.5
Interquartile range =Q3-Q1
=5.5-3.5
=2
Answer:
1.6
Step-by-step explanation:
Lets count how many points are x and y away from each other since we dont have a graph.
X and Y points:
35-15=20
56-24=32
Use the formula:
32/20 = 1.6
Answer:
Her cousin used Yard to measure the wall.
Step-by-step explanation:
Firdaus measured the length of the wall and got 9 feet.
Her cousin measured the same distance and said that it was 3.
To find the answer, we have to use division.
Let "x" the divisor which divide 9 and gives the answer 3.
9 ÷ x = 3
3x = 9
To find x (divisor) we need to divide both sides by 3, we get
3x ÷ 3 = 9 ÷ 3
x = 3
So 1 unit cousin's measure = 3 feet Firdaus measure
We know that 1 yard = 3 feet.
Therefore, her cousin used Yard measure to measure the wall.
