Answer:
x = 108
Step-by-step explanation:
The sum of a circle is 360
90 + x/2 + x+x = 360
Combine like terms
90 + 2x+x/2 = 360
90 + 5/2 x = 360
Subtract 90 from each side
5/2x = 270
Multiply each side by 2/5
5/2x * 2/5 = 270*2/5
x =108
(a) Carson's statement is always true.
For example: (-7.2)/(-2.4)= 3 >0
(-1.6)/(-0.8)= 2 >0
(b) When we divide two negative decimals, we divide the decimals and don't care about the sign, for the sign is always positive.

Answer:
Step-by-step explanation:
So we have direct proportions here.
So
715=11
845=x
845*11/715
x=13
To check our work.
715/11=65
65*13=845.
Basically, in this formula, you use cross multiplication. So A*B=B*A. B and B go together and A and A go together/
So we can use the formula x = b*b/a. Since A is one of the A's and the other value of A is missing, we can use this formula to find it.
Hope this helped, ask me if you have any questions.

Answer:
Step-by-step explanation:
The simple answer is just move the left semi-circle to the right end and fill in the missing semi-circle. So the answer just becomes the area of the full rectangle....
area of the newly formed rectangle is 4 times 6
Area = 24
