Assume all items are Lipgloss
Total Cost -> $7 x 9 = $63
difference-> $63-$50.50= $12.50
Assume that all were Lipgloss except for one item
Total Cost-> ($7x8)+$4.50= $60.50
diff-> $63-$60.50=$2.50
Number of Nail Polishes-> $12.50 diveded by $2.50 = 5
Number of Lipglosses-> 9-5=4
ANSWER:
Lipglosses:4
Nail Polishes :5
Answer:
m =
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 4x + 7 is in this form with slope m = - 4
Given a line with slope m then the slope of a line perpendicular to it is
= - = - =
Hence the value of m =
Answer:
154 sweets
Step-by-step explanation:
Adrian, Ben and Charlie share some sweets in the ratio 5:2:7 and Charlie got 22 more sweets than Adrian.
Let the total number of sweets be x.
Then Adrian gets:
And Charlie gets:
It was given that Charlie got 22 more sweets than Adrian.
This implies that:

Argument
The only number he can't roll is the number one. There are 5 numbers that he can roll.
The probability of success therefore is 5/6.
Formula
Number of successful rolls = probability of success * total number of rolls.
Total number of rolls = 78
Probability = 5/6
Number of successful Rolls = 5/6 * 78
Number of successful Rolls = 390/6
Number of successful Rolls = 65
Answer
He should roll a number greater than one 65 times <<<<< answer
