Answer:
C.) 2 1/2
Step-by-step explanation:
X + 2 1/4 = 4 3/4
Change the fractions to improper fractions .
We have
X + 9/4 = 19/4
Subtract 9/4 from both sides
X + 9/4 - 9/4 = 19/4 - 9/4
X = 19/4 - 9/4
Look for the LCM of the denominators.
The LCM is 4
Divide the LCM by the denominators and multiply the results by the numerators, the lcm becomes the denominator of the results.
That’s
X = 19 - 9 /4
= 10/4
Divide both numerator and denominator by 2
= 5/2
= 2 1/2
If you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14. You can also work out the circumference of a circle if you know its radius.
He should have added 1 to both sides to make the -1 on the right go to 0.
Then it would be 0 + m = -16 + 1 = -15
You can check your work by adding -1 and -15, which does in fact equal -16.
