storchak [24]

Answer:

Bob forgot to distribute 3 to 1.50 in the parentheses

Step-by-step explanation:

Bob made the mistake in his first step.

In the equation 3(x + 1.50) = 30, the 3 has to be distributed to both x and 1.50.

But, Bob only distributed it to x, which led him to get the wrong answer.

So, Bob's mistake when solving was that he forgot to distribute the 3 to 1.50

Simplify (3x - 2) - (3x + 6)

Naddika [18.5K]

(3x - 2) - (3x+ 6)=

3x - 5) + (3x + 6)

3x - 5 + 3x + 6

Combine the 'x'-terms: 3x + 3x = 6x
Combine the numbers: -5 + 6 = 1

The expression is equivalent to . . . . . 6x + 1

Sandra sets the cruise control in her car to 69 miles per hour when she goes on road trips. Which equation can be used to find h

jarptica [38.1K]

Answer: $h=\frac{m}{69}$

Step-by-step explanation:

For this exercise is necessary to remember the following formula:

$V=\frac{d}{t}$

Where "V" is the speed, "d" is the distance and "t" is the time.

In this case you must solve for the time, then:

$tV=d\\\\t=\frac{d}{V}$

Based on the information provided in the exercise, you can identify that:

$V=69\\\\t=h\\\\d=m$

Therefore, knowing this, you can make the substitution into the formula $t=\frac{d}{V}$ .

Through this procedure you get that the equation that can be used to find the amount of hours "h" that it will take Sandra to drive "m" miles at her constant speed, is:

$h=\frac{m}{69}$
