Answer:
The numbers are 27 and 12
Step-by-step explanation:
Let the smaller number be x and the larger number be y.
If the difference between them is 15, then
Also , four times the larger number is nine times the smaller.
From equation (1),
We put the 3rd equation into the 2nd to get:
Expand to get:
Group similar terms
Therefore the larger number is
10/16, u just double 5/8 because 16 is double of 8.
The equation given in the question has one unknown variable in the form of "x" and only one equation is required to find the value of the unknown variable. So it is absolutely possible to find the exact value of "x".
6(-3 - x) - 2x = 14
-18 - 6x - 2x = 14
-18 - 8x = 14
Multiplying both sides of the equation by -1 we get
8x + 18 = - 14
Dividing both sides by 2 we get
4x + 9 = - 7
4x = - 7 - 9
4x = - 16
x = - 16/4
= - 4
So the value of "x" comes out to be equal to - 4. I hope the procedure is clear enough for you to understand.
Answer:
18.36
Step-by-step explanation:
To find the height you draw in a line from the vertex to the base and then you use cos(63)=x/9 so you do cos(63) multiplied by 9 to reach 18.36
You want x/n to be greater than x.
n must be between 0 and 1.
