For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
We now write the expression that models the problem:

From here, we clear the value of x.
We have then:




Answer:
4/9 divided by 1/27 equals 12
Answer: Think it is -3/5
Step-by-step explanation:
6-5(x)=9

6+3=9
9=9
Answer:
-21, -16, 4, 9
Step-by-step explanation:
-3: f(-3) = 5(-3)-6 = -15-6 = -21
-2: f(-2) = 5(-2)-6 = -10-6 = -16
2: f(2) = 5(2)-6 = 10 - 6 = 4
3: f(3) = 5(3)-6 = 15 - 6 = 9
Answer:
D. 10.91 square centimeters
Step-by-step explanation:
Area of a sector of a circle =


where 
radius (r) = half of diameter = 10/2 = 5 cm
Area = 
= 10.91 
Answer:
Take the starting point as the first natural number that is 1.
Step-by-step explanation:
To find: a starting point so that the first 5 numbers in the sequence are all positive
Solution:
Natural numbers are numbers that are used for counting.
Natural numbers are basically positive integers.
Take the starting point as the first natural number that is 1.
The next point as 2.
The next point as 3.
The next point as 4.
The next point as 5.
So, the sequence becomes
so that the first 5 numbers in the sequence are positive.
