Answer:
I dont k ow what the following set for your equation is...
X=hours of plan A
y=hours of plan B
wed: 5x+6y=12
thu: 3x+2y=6
so
5x+6y=12 and
3x+2y=6
we can eliminate y's by multiplying 2nd equation by -3 and adding to first equation
-9x-6y=-18
<u>5x+6y=12 +</u>
-4x+0y=-6
-4x=-6
divid both sides by -4
x=-6/-4
x=3/2
x=1.5
sub back
3x+2y=6
3(1.5)+2y=6
4.5+2y=6
2y=1.5
y=0.75
Plan A=1.5 hours
Plan B=0.75 hours

Answer:

Step-by-step explanation:
we know that
1 mile=63,360 inches
step 1
Find the circumference of the wheels

we have
-----> the radius is half the diameter
substitute


assume


Remember that
The circumference of the wheels represent one revolution
Convert 59 miles per hour to inches per minute

using proportion find the number of revolutions

therefore
substitute
