Answer:

x=-1

y=2

Step-by-step explanation:

3x+2y=1

x-3y=-7

x=3y-7

3(3y-7)+2y=1

9y-21+2y=1

11y=1+21

11y=22

y=22/11=2

x=3(2)-7=6-7=-1

The diameter of a truck tire is 22inches Approximately how fat will the truck have traveled after 5 rotations of these tires

kvasek [131]

Answer:

The truck have travelled 345.5 inches after 5 rotations of the tires

Step-by-step explanation:

Given:

Diameter of the tyre= 22 inches

Number of rotations= 5

To find:

Distance travelled after 5 rotations=?

Solution:

We have given with diameter,

So let radius be r

r= $\frac{diameter}{2}$

$r=\frac{22}{2}$

r=11 inches

The distance covered by one rotation is given by circumference

Circumference = $2\pi r$

Substituting the values, we get

Circumference = $2\times\pi\times r$

Circumference = $2\times\pi\times 11$

Circumference = $2\times\3.14\times 11$

Circumference = $6.28\times 11$

Circumference = 69.11

Now for 5 rotation,

Distance travelled = $5\times(\text{circumference value})$

Distance travelled = $5\times(69.11)$

The truck will travel 345.5 inches.
