Michelle has decided to switch from her 24-inch tires to low-profile tires, which will decrease the diameter of her tires to 20 inches. How many rotations more, to the nearest whole
rotation, will the new tire make in order to travel one mile?

184

Step-by-step explanation:

Regular Tire:

Circumference = x d

= x 24

= 75.4 inches

1 Mile = 63360 Inches

Therefore 63360/75.4 = Number of time tires rotated

= 840 rotations

Low Profile Tire:

Circumference = x d

= x 20

= 62.83 inches

1 Mile = 63360 Inches

Therefore 63360/62.83 = Number of time tires rotated

= 1008 rotations

Increased Rotations:

1008 - 840 = 168

Therefore the new tires make 184 more rotations.

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
