Rent = 360
Groceries and hhold goods = 240
Given:
Weekly pay = 720
Groceries and household goods = 1/3 of weekly pay
Rent = 3/4 of money net from groceries.
720 * 1/3 = (720*1)/3 = 240 groceries and household goods
720 - 240 = 480 remaining money for rent
480 * 3/4 = (480*3)/4 = 1440/4 = 360 rental payment
480 - 360 = 120 remaining money.
Joanne spends 360 for rent and 240 for groceries and hhold goods.

Try this on for size.
Step-by-step explanation:
Let's solve your system by substitution.

y
=
x
+
19
Step: Solve
y
=

for y:
y
=

5
Step: Substitute
3
x
+
5
for
y
in
y
=

(Divide both sides by 2)
x
=

(Simplify both sides of the equation)
Answer:
x

and
y
=

Answer:
y = -2x + 4
Step-by-step explanation:
First find slope:
We know equation of a line is y = mx + b, where m = slope and b = y-intercept, so we can plug in the slope:
y = -2x + b
The y-intercept of the equation is 4 because the coordinate (0, 4) is given. Therefore, the equation is:
y = -2x + 4
