If the sum of a number and four is doubled, the result is one less than the number. Find the number.
diamong [38]

Answer:

Step-by-step explanation:

Equation

2(x + 4) = x - 1

Solution

2x + 8 = x - 1                Subtract x from both sides

2x-x + 8 = - 1                Combine the left

x + 8 = - 1                     Subtract 8 from both sides

x + 8-8 = - 1-8

x = - 9

Check

<em>LHS</em>

2(-9 + 4)

2(- 5)

-10

<em>RHS</em>

-9 - 1

- 10

C)<br> A bus drives for 3/2 hours at an average speed of 56 mph.<br> How far does the bus drive?
natta225 [31]

Answer:

The bus drives 84 miles

Step-by-step explanation:

The question relates to relationship between average speed and time

The given parameters are;

The time duration in which the bus drives = 3/2 hours = 1.5 hours

The average speed of the bus = 56 mph

The formula average speed is given as follows;

Average \ speed = \dfrac{The \ total \ distance \ driven}{The \ time \ duration \ of \ travel}

Therefore, we have;

The total distance driven = Average speed × The time duration of travel

The total distance driven = The distance the bus drives

Substituting the given values, gives;

The distance the bus drives = 56 miles/hour × 1.5 hours = 84 miles

The distance the bus drives = 84 miles.
