Cassie has 30 marbles. Abdul has m marbles. If Cassie has 10 times as many marbles as Abdul, write an equation that shows how many marbles Abdul has.

30=10m

m=3

Step-by-step explanation:

On the other side should be an expression representing how many marbles Cassie has in terms of the number of marbles that Abdul has. Abdul has m marbles, and Cassie has ten times that many. Wouldn't that be 10m? That should be placed on the right-hand side of the equation. From there, it should be fairly simple to solve for m.

Hope this helps!!

(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

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)
