Answer:
-3/5
Step-by-step explanation:
First represent this with numbers. Less means subtraction -, times means multiplication *, is means equals =.
And let's represent "a number" with x.
63 - 15x = 72
Solve for x. First subtract 63 from both sides.
-15x = 72-63
-15x = 9
x = -9/15 = <u>-3/5</u>
Answer:

Step-by-step explanation:
The experimental probability of heads is
P( heads) = 28/50 = 14/25
The theoretical probability is
P (heads) =1/2
Getting a common denominator for the experimental
25/50
comparing the experimental and the theoretical
28/50 > 25/50
experimental > theoretical
Answer:
Step-by-step explanation:
LCM of 3 and 6 = 6
2/3 = (2×2) / (3×2) = 4/6
4/6 = (4×5) / (6×5) = 20/30
5/6 = (5×5) / (6×5) = 25/30
Hence, 21/30, 22/30, 23/30 and 24/30 are four rational numbers between 2/3 and 5/6.
Let x = number of hours required to fix the computer
$230 = $25x + $155
To solve for x, subtract $155 from both sides.
$75 = $25x
Divide each side by $25
3 = x
It took 3 hours to fix the computer
