Answer:
7 parts
Step-by-step explanation:
To get the answer to this, we only simply to know the number of times in which the division was made.
This means that the total ratio of the lines is 2 +5 = 7. Meaning we have 7 different divisions.
The first division carries 2/7 while the second division carrues 5/7
10 separated into 5 groups is 10/5
5 goes into 10 2 times.
10/5=2
Answer: 200
Step-by-step explanation:
since 10 is one part
10 x 20 = 200
The 3rd one
This is because in the graph it’s looking for numbers 70-79 but only with 2 numbers and the 3rd is the only one that fits in the description.
X^2/(x- 9 = 81/(x - 9)
This is the equation for which you want the solution.
Multiplying both sides of the equation by (x - 9) we get
x^2(x - 9)/(x - 9) = 81(x - 9)/(x - 9)
So the (x - 9) goes out from both the denominator and the numerator and then the simplified equation becomes
x^2 = 81
x ^2 = (9)^2
x = 9
So the value of the unknown variable x comes out to be 9.
