An athlete completes a race in 55.72 seconds how many times greater is the digit in the tens place than the digit in the ones place

The value of digit in tens place is 10 times greater than the value of digit in ones place.

Step-by-step explanation:

Let the value of digit in tens place be x times the value of digit in ones place.

We are asked to find the value of the digit in the tenths place is how many times as much as the value of the digit in the thousandths place.

55.72

Ones: 5

Tens: 5

Therefore, the value of the digit in the tens place is 10 times greater than the value of the digit in the ones place.

(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
