There are 10 lanes in the bowling alley where Harold bowls. He wants to make a scale drawing of the bowling alley using a scale of 3 cm to 15 ft. One lane,

including gutters, is 60 ft long and 5 ft wide. What will the width of all 10 lanes on

his drawing be?

please help this is urgent!! provide good for explanation✨

Step-by-step explanation:

Given that the scale of the drawing is  3 cm to 15 ft.

This means that, every 15ft in the drawing will be represented by 3cm.

also there are a total of 10 lanes

given that the width of one lane is 5ft, the ten will be 5*10= 50ft

Now how many 15ft are there in 50ft= 50/15= 3.33

now in cm = 3.33*3=10cm

therefore on the drawing the width will be 10cm

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1
