Answer:
I may be wrong but i think the answer is D
Step-by-step explanation:
We know that y=10, so if we were to multiply 10 by 7.50, it would be 75, not 63, so A and B wouldn't be correct. and we don't know the value of x, so I think D is the best answer.
12=5x-13x-44
combine like terms
12 = -8x -44
add 44 to each side
12+44 = -8x
56= -8x
divide by -8 on each side
56/-8 = x
-7 =x
I believe that when finding the radius of a circle you half the diameter, but when finding the circumference of a circle you need to multiply the diameter (14cm) by pi.
So 14xpi= 43.98229715
But it can be simplified/ rounded to 44cm.
Of course I might be incorrect so do please correct me if I am wrong.
