Answer:
x = 18
Step-by-step explanation:
Subtract 5 on both sides:
-2x + 5 =- -31
-5 -5
-2x = -36
Divide by -2 on both sides:
-2x = -36
/-2 /-2
x = 18
First you find a common denominator, which is 12 ( as 4,3 and 6 all go into 12). So 2/4 becomes 6/12, as 4 multiplied by 3 is 12 and whatever you do to the denominator you must do to the numerator. Then 2/3 becomes 8/12. And 2/6 becomes 4/12. If you put these in order the answer is:
2/6, 2/4, 2/3
Answer:
-8
Step-by-step explanation:
first combine like terms 5x+5x=10x
then subtract 5 from -75= -80
divide -80 by 10= -8
you are left with -8=x
Answer:
78.54 m^2
Step-by-step explanation:
The computation of the area of the circle is shown below:
As we know that
Area of the circle = πr^2
Also
Diameter = 2r
10 = 2r
r = 5
So, the area of the circle is
= 3.14 × 5^2
= 78.54 m^2
