Jessica is making $300 less than four times what she was making when she started working. Let a represent her starting salary. Write an expression showing how much Jessica is making now.

Solution:

Given that,

Let "a" represent her starting salary

Jessica is making $300 less than four times what she was making when she started working

Therefore,

Jessica salary now = $300 less than four times the starting salary

Jessia salary now = 4 times the starting salary - 300

Jessia salary now = 4a - 300

Thus the above expression denotes how much Jessica is making now

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
