Cameron earned $46 raking leaves. if he worked 1.5 hours yesterday and 4.25 hours today, how much did he earn per hour

$8

Step-by-step explanation:

1.5+4.25=5.75

5.75x=46

5.75x/5.75=46/5.75

x=8

8 dollars per hour

Step-by-step explanation:

1. 4.25 + 1.5= 5.75 which is the total hours

2. Then 46÷5.75 would be 8. so 8 dollars per hour.

Example: 8×2 hours=?

16$

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
