Answer:
x = 6
Step-by-step explanation:
put '3' in where 'y' is :
7x + 2(3) = 48
7x + 6 = 48 subtract 6 from both sides of the equation
7x = 42 divide both sides by 7
x = 6
Let's translate this question into a formula:
Total cost = (unit price of the eraser) (number of erasers purchased)
Final total cost = (Total cost) * 1.08 = ?
Why? The Final Total Cost = Cost of the erasers + (Cost of the erasers)(sales tax rate)
Final total cost = 1.08 (Total Cost)
Final total cost = 1.08 ($0.50)(24) (since 1 dozen = 12, and 2 dozen = 24)
Multiplication would be the inverse operation of division. so it would be, 3 x 34 = 102
Answer:
1.48 m
Step-by-step explanation:
In a class of 32 students
the mean height of the 14 boys is 1.56 meters.
the mean height of all 32 students is 1.515 meters.
Total number of students = 32
Mean height of all students = 1.515
We can obtain the sum of all student's height :
Number if students * mean height
= 32 * 1.515
= 48.48
Number of boys = 14
Mean height of boys = 1.56m
We can obtain the sum of all boys height :
Number if students * mean height
= 14 * 1.56
= 21.84
Number of girls :
All students - Number of boys
32 - 14 = 18
Sum of girls height :
48.48 - 21.84 = 26.64
Mean height of girls :
Sum of girls height / Number of girls
26.64 / 18
= 1.48 m
