Answer:
x = 16
Step-by-step explanation:
x
-- = 9-1 ...... first shift 1 and it will be -1
2
x = 8 ....... secondly 9-1 =8
--
2
x = 16 ..... criss cross and 2×8 = 16
there fore the value of x is equals to 16.
you can check it!
Answer:
Circumference: 37.68
Area: 113.04
Step-by-step explanation:
the formula to find the circumference is 2 x 3.14 x r
r is the radius so you plug in 6 for that
2 x 3.14 x 6 = 37.68
the formula to find the area of a circle is 3.14 x r ²
r is still the radius so you plug in 6 for that
3.14 x 6² = 113.04
Answer:
(-1/3, 3/4)
Step-by-step explanation:
9x + 8y = 3
6x - 12y = -11
Let's solve the system by eliminating x. We need the coefficients of x to be additive inverses, so they will add to zero eliminating x. The LCM of 9 and 6 is 18. Let's multiply both sides of the first by 2 and both sides of the second equation by -3.
18x + 16y = 6
-18x + 36y = 33
The coefficients of x are 18 and -18, which add to zero. Now we add these two equations.
52y = 39
y = 39/52
y = 3/4
Now we substitute y with 3/4 in the first equation and solve for x.
9x + 8y = 3
9x + 8(3/4) = 3
9x + 6 = 3
9x = -3
x = -3/9
x = -1/3
Solution: (-1/3, 3/4)
