There are 10 digits 0 1 2 3 4 5 6 7 8 9 if we can't use 0 and 1 then there are only 8 choices for the first digit and only 2 choices for the second digit and 10 for the third so there are 8*2*10 =160 possibilities.
Answer:
There are 2 hours and 30 minutes in 150 minutes.
Step-by-step explanation:
<span>Simplifying
3(5 + -1e) + 2 = 10
(5 * 3 + -1e * 3) + 2 = 10
(15 + -3e) + 2 = 10
Reorder the terms:
15 + 2 + -3e = 10
Combine like terms: 15 + 2 = 17
17 + -3e = 10
Solving
17 + -3e = 10
Solving for variable 'e'.
Move all terms containing e to the left, all other terms to the right.
Add '-17' to each side of the equation.
17 + -17 + -3e = 10 + -17
Combine like terms: 17 + -17 = 0
0 + -3e = 10 + -17
-3e = 10 + -17
Combine like terms: 10 + -17 = -7
-3e = -7
Divide each side by '-3'.
e = 2.333333333
Simplifying
e = 2.333333333</span>
Answer:
Because the slope is going up and not down?
Step-by-step explanation:
We need to compute for the length of each trophy given that one trophy is 5 inches wider than the other.
Let x be the length of the first trophy.
Let x+5 be the length of the second trophy
The solution is shown below:
x + (x + 5) = 17
x + x + 5 =17
2x =17 -5
2x = 12
x = 12/2
x=6 (for the first trophy)
x + 5 = 6+5 = 11 (for the second trophy)
The first trophy is 6 inches wide while the second trophy is 11 inches wide.
