Answer:
x = 3 sqrt(2)
Step-by-step explanation:
x -√2=√8
Add sqrt(2) to each side
x - sqrt(2) + sqrt(2) = sqrt(8)+ sqrt(2)
x = sqrt(8)+ sqrt(2)
Rewriting sqrt(8) as sqrt(4) sqrt(2) = 2 sqrt(2)
x = 2 sqrt(2)+ sqrt(2)
x = 3 sqrt(2)
Answer:
Postcards bought was 9
Step-by-step explanation:
<h3>
<u>P = 3D</u></h3>
where,
- P = total number of postcards
- D = days of vacation = 3 days
⟼ P = 3D
prince number of days of vacation is 3 therefore we multiply 3 by 3
⟼ P = 3(3)
multiply 3 by 3
⟼ P = 9

Answer:
Company B's offer is more cost effective
Step-by-step explanation:
Expected no. of repairs:
(0)(0.25) + (1)(0.32) + (2)(0.29) + (3)(0.14)
= 1.32
Cost A: 12.99 × 12 = $155.88
Cost B: 1.32 × 75 = $99
If the 3/5 was a whole number, it would all be simple. We would just put the number above 4 and divide. Easy, right?
Well, you do basically the same thing. Since having fractions over fractions confuse me, I'm going to put 3/5 into a decimal.
3/5=6/10=0.6
Now, I put that over 4, because there are 4 bottles.
0.6/4=6/40=3/20
She put 3/20 gallons into each bottle. Hope this helped!
