Bianca wrote the steps for her solution to the equation 2.3 + 8(1.3x – 4.75) = 629.9. She left out the description for the last

step. A table titled Bianca's Solution with 2 columns and 5 rows. The first row has the entries, blank, Steps, Resulting equations. The second row has the entries, 1, Use the distributive property to simplify, 2.3 plus 10.4 x minus 38 equals 629.9. The third row has the entries 2, Combine like terms, 10.4 x minus 35.7 equals 629.9. The fourth row has the entries, 3, Use the addition property of equality, 10.4 x equals 665.6. The fifth row has the entries, 4, blank, x equals 64. What is the missing step of her solution? Add 10.4 to both sides. Add negative 10.4 to both sides. Multiply both sides of the equation by 10.4. Divide both sides of the equation by 10.4.

The diameter of the wheels on your car is 25 inches. You are going to drive 458 miles today. Each of your wheels is going to tur
Kipish [7]

d = Diameter of wheels = 25 inches

s = Distance to be traveled by the wheels = 458 miles

Converting the miles to inches

s=458\times 5280\times 12=29018880\ \text{inches}

The distance traveled by the wheels in rotation is the circumference

D=\pi d\\\Rightarrow D=\pi\times 25

The number of rotations required to cover the distance would be

\dfrac{s}{D}\\ =\dfrac{29018880}{\pi\times 25}\\ =369479.855599

1 rotation is 360^{\circ} so

369479.855599\times 360=133012748.016^{\circ}

The number of rotations to cover the required distance is 133012748.016^{\circ}

What’s the inverse of 4x + 12
stiks02 [169]

Answer:

1/4x -3

Step-by-step explanation:

To find the inverse of a function, exchange x and y and then solve for y

y =4x+12

Exchange x and y

x = 4y+12

Solve for y

Subtract 12 from each side

x-12 = 4y+12-12

x-12 = 4y

Divide by 4

(x-12)/4 = 4y/4

The inverse is

1/4x -3
