Answer:
a1
Step-by-step explanation:
Just add the numerators if both fractions to get: a + 1 = a1
(3x3) -3- (3/3) -3
9-3-1-3
6-4
2
So, using our given information, we have a line of the equation
, or
. Plugging in our value 9 for
, we get
.
j=3
First let's get rid of the parenthesis:
12 - 4x + 3x = 4 + 10 + 2x
Now group the x's on the left and the numbers on the right
-4x + 3x - 2x = 4 + 10 - 12
...and simplify
-3x = 2
divide by -3 to isolate x
x = -2/3
Answer:
132 ft
Step-by-step explanation:
The radius is 21 ft
We want to find the circumference
C = 2 * pi *r
Letting pi = 22/7
C = 2 * 22/7 * 21
C = 132 ft
