Step-by-step explanation:
Conversion a mixed number 5 3/2
to an improper fraction: 5 3/2 = 5 3/2
= 5 · 2 + 3/2
= 10 + 3/2
= 13/2
To find a new numerator:
a) Multiply the whole number 5 by the denominator 2. Whole number 5 equally 5 * 2/2
= 10/2
b) Add the answer from previous step 10 to the numerator 3. New numerator is 10 + 3 = 13
c) Write a previous answer (new numerator 13) over the denominator 2.
Five and three halfs is thirteen halfs
Conversion a mixed number 3 6/7
to an improper fraction: 3 6/7 = 3 6/7
improper fraction: 3 6/7 = 3 6/7
3 · 7 + 6/7 = 21 + 6/7 =27/7
To find a new numerator:
a) Multiply the whole number 3 by the denominator 7. Whole number 3 equally 3 * 7/7
= 21/7
b) Add the answer from previous step 21 to the numerator 6. New numerator is 21 + 6 = 27
c) Write a previous answer (new numerator 27) over the denominator 7.
Three and six sevenths is twenty-seven sevenths
Multiple:
13/2 * 27/7 = 13/2 · 27/7 = 351/14
Jeremy's total monthly costs amount to
$1500 + 6000 = $7500
Jeremy gets revenue of
(12×$3)×(1 - 0.10) = $32.40
per box of chocolates sold.
In order to cover costs, Jeremy must sell each month
$7500/($32.40/box) = 232 boxes . . . . . . (rounded up so costs are covered)

Answer:
The coordinates of point E are (-19/4,8)
Step-by-step explanation:
To find this, we use the internal division formula;
The formula is as follows;
(x ,y) = mx2 + nx1/(m + n) , my2 + ny1/(m + n)
From the question;
m = 5 n = 3
x1 = -1 , y1 = -5
x2 = -7 , y2 = 11
Substitute these values;
(x ,y) = 5(-7) + 3(-1)/(3 + 5) , 5(11) + 3(-5)/(5 + 3)
(x , y) = (-35-3)/8, (55-15)/8
(x,y ) = -38/8, 40/8
(x,y) = -19/4, 5
Answer:
y>4
Step-by-step explanation:
3y>12
divide both sides by 3
y>4
