Answer: $312.5
Step-by-step explanation:
Lily spent one-fifth of her salary on a pair of shoes and then got $90 as a birthday present from her mom and was left with $340. To calculate the amount Lily had at first goes thus:
Since Lily spent 1/5 on shoes, that means she had (1 - 1/5) = 4/5 left.
Let the amount she had at first be y.
(4/5 of y) + 90 = 340
(4/5 × y) + 90 = 340
0.8y + 90 = 340
0.8y = 340 - 90
0.8y = 250
Divide both side by 0.8
0.8y/0.8 = 250/0.8
y= 312.5
She had $312.5 at first.
Answer:
5
Step-by-step explanation:
There are 6 numbers on a die, one of them is 5 so we expect to get a five one of six times
P (5) = 1/6
If we roll the die 30 times, we expect to get a five 30 * 1/6 = 5 times
The theorem is correct because of the fact that they all equal the same...
: 6
:
- i just plugged in every number in.
4 + 5 > 10
9 > 10? nope.
5+5 > 10
10 > 10 ? nope.
6+5 > 10
11 > 10? YES.
