If you're talking about just the decimal, then yes it is.
If you're talking about 22/7, then it still is.
But if you're talking about pi, then it isn't rational.
Step-by-step explanation:
The Answer should be 10 as the diving board is the same distance above the surface which is 10
So, let's say the soft drink equals y and the sandwich equals x.
x + y = 9.9
The sandwich costs 3.5 times as much as the soft drink
x = 3.5y
Therefore, we can replace x with 3.5y since they're the same thing
3.5y + y = 9.9 <-- That's the equation :)
Answer:
Y=1 X=0
Step-by-step explanation:
Hi Brainiac
7/8 =?/48
Let's replace the unknown place by x
7/8 = x/48
Cross multiply
(7)(48)= (X)(8)
336 = 8x
Flip it
8x = 336
Divide both sides by 8
8x/8 = 336/8
x= 42
The answer is C
Now if you wanna see if the answer is good just replace 42 in blank space
7/8 = 42/48
Now didivde 7 by 8 and divide 42 by 48
7/8= 0.875
42/48= 0.875
The answer C is correct
I hope that's help:)
