Answer:
4
Step-by-step explanation:
if the required number is 'x', then the sum of 2 times the number and 10 is 2x+10; the difference of the number and 1 is x-1. Using these two equation it is possible to make up the common one:
2x+10=6(x-1);
4x=16;
x=4.
Answer:
(a) Circle Q is 9.4 units to the center of circle P
(b) Circle Q has a smaller radius
Step-by-step explanation:
Given
Solving (a): The distance between both
The equation of a circle is:
Where
P and Q can be rewritten as:
So, for P:
For Q:
The distance between them is:
Where:
---
---
So:
Solving (b): The radius;
In (a), we have:
--- circle P
--- circle Q
By comparison
<em>Hence, circle Q has a smaller radius</em>
X% means X/100
To change percent to decimal divide it with 100.
Example 75% = 75/100 = 0.75
In order to know that, you need to divide 28 from 126
It would be:126/28 = 4.5
So, your final answer is 4.5
Hope this helps!
