Add 5 to 19 which is 24 then divide it by -6 and it’s x= -4
Area of a circle = πr^2
18 inches = 9 inches (radius)
A = π×9^2
A = 81π inches^2
Or...
A = 81×π
A = 254.5 inches^2 (1 dp)
Answer:
The second and third one.
Step-by-step explanation:
If you use a calculator and do 3 x 3 x 3 x 3 x 3 it equals 243. If you do 3 x 3 x 3 x 3 it equals 81 and then you do 81 x 3 it equals 243.
I hope this helps.
Multiply both sides by 3 and get 2x - 20 = 6x
Then subtract 2x from both sides and get
-20 = 4x. Divide both sides by 4 and then get x = -5
<span>Pru and Piper have apples is ratio 5:3
Let No. of apples with Pru = 5a
and no. of apples with Piper = 3a
and no. of apples with Phoebe = 4a
5a - 3a = 24
2a = 24
a=12
No. of apples with Phoebe = 4x12=48
Hence Phoebe has 48 apples.</span>
