-----------------
To solve this all it takes is two simple steps
Simplify
1/2x =22
------------------------
Multiply both sides by 2
2 ·
= 2 · 22
x = 44
x=3, you can find this by using finding common bases for equation b because 243=3^5. Because of that you can get rid of three on both sides to get the equation 2x-1=5 and then just solve for x to get x=3. For the first equation 5^3=625 so that also proves x=3.
Sorry if my explanation is a little disorganized if you need more help feel free to ask
Answer:
(a x 4)+(a x 3)=7a
Step-by-step explanation:
(a x 4)+(a x 3)= 4a+3a
(a x 4)+(a x 3)=7a
or does your question means something else??
It would cost $132. 7+7+15+15X3=132
Look carefully at the diagram. The shaded region represents 3/4 of the total area of the circle, which, in turn, is pi*r^2, or pi*(8 cm)^2.
Thus, the area of the shaded region is (3/4)*pi*(64 cm^2), or 48 pi cm^2.
