Answer:
9
Step-by-step explanation:
x-5+7=11
First think of what +7 = 11 then subtract by 5
check :)
Answer:
C=6π
Step-by-step explanation:
It is given that, two circles are identical. The radius of first circle is 2x and the diameter of other circle is 2x+3.
If identical, it means that the radius of both circles are same i.e.

Radius of both circles is 2(1.5)=3
The circumference of a circle is given by :

So, the circumference of each circle is 6π.
Answer:
Step-by-step explanation:All other quantities of physical objects can be expressed as combinations of these fundamental quantities. For example, density is volume per mass. It can be expressed as a combination of the fundamental quantities mass (M) and length (L), M/(L × L × L) = M/L3. Similarly, area is a function of length, L × L = L2.
Answer:
5 hours
Step-by-step explanation:
Electrician got 90 for the first hour from the total bill, thus we can say:
330 - 90 = 240 remaining for remaining hours
$60 per hour, so $240 for how many hours?? We divide:
240/60 = 4 hours
So, electrician works 4 hours for 60 per hour = 2 * 6 = 240
and 1 hour for 90 (first hour) = 1 * 90 = 90
Total Bill is 240 + 90 = 330 {exactly what we have}
So we have checked and back-worked our problem to get electrician's total hours of work:
1 + 4 = 5 hours
The question is an illustration of angles on a straight line
The value of x is 25.4
<h3>How to determine the value of x</h3>
In the figure, angles 1 and 2 are angles on a straight line
Where:
- Angle 1 = 4x - 8
- Angle 2 = 3x + 10
So, we have:

Collect like terms


Divide through by 7

Hence, the value of x is 25.4
