H/6-1=-3 so what does h equal
svet-max [94.6K]

Answer:

H=-12

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

h/6-1=-3

1/6h+-1=-3

1/6h-1=-3

Step 2: Add 1 to both sides.

1/6h+1=-3+1

1/6h=-2

Step 3: Multiply both sides by 6.

6*(1/6h)=6*(-2)

H=-12

Hope this helps

11111nata11111 [884]

Answer:

Wheel1 = 147inches , wheel 2 = 113inches

Wheel 1 will travel 147 revolutions.

Step-by-step explanation:

Finding the circumference of both wheels

Wheel 1 = 2 pi r = 2 × 3.142 × 23.4 = 147.05 inches. To the nearest inches = 147inches

Wheel 2 = 2 pi × r = 2 × 3.142 × 18 = 113.11inches . To the nearest inches = 113inches.

I rotation = 1 revolution

In 1 rotation, wheel 1 will travel= 147 × 1 = 147 revolutions.
