Solve for b. 3-2(b-2)=2-7b3−2(b−2)=2−7b

Mathematics

lyudmila [28]2 years ago
3 0

Step-by-step explanation:

3 - 2(b - 2) = 2 - 7b

To solve this first distribute -2 to (b - 2)

3 + (-2b + (-2) x -2) = 2 - 7b

when we simplify this it becomes:

3 + (-2b + 4) = 2 - 7b

We take (-2b + 4) out of the parenthesis:

3 - 2b + 4 = 2 - 7b

Now simplify again.

7 - 2b = 2 - 7b

Now send all the b's to one side and constants on the other.

7 - 2 = -7b +2b

5 = 5b

b = 1

It will take Adam four hours to drive to Disney Park, and 2.5 times less time if driving 45 mph faster. What is the distance Ada
Butoxors [25]
<h2>Hello!</h2>

The answer is:

The distance that Adam should cover to get to the park is 108 miles.

<h2>Why?</h2>

To solve the problem, we need to write two equations with the given information about the times and his speed.

So,

For the first equation we have: Going to Disney Park

time=4hours

Distance=v*4hours

For the second equation we have: Going back from Disnery Park

time=4hours-2.5hours=1.5hours

Speed=v+45mph

Distance=(v+45mph)*1.5hours

Now, if He covered the same distance going and coming back, we have:

v*4hours=(v+45mph)*1.5hours

v*4hours=v*1.5hours+45mph*1.5hours

v*4hours-v*1.5hours=45mph*1.5hours

v*2.5hours=67.5miles

v=\frac{67.5miles}{2.5hours}=27\frac{miles}{hour}=27mph

We have that the speed when Adam was going to Disney Park was 27 mph.

Therefore, to calculate the distance, we need to substitute the obtained speed in any of the two first equations.

Then, substituting the speed into the first equation, we have:

Distance=v*4hours\\Distance=27mph*4hours=108miles

Hence, we have that the distance that Adam should cover to get to the park is 108 miles.

Havea nice day!

Write an equation of a line that is perpendicular to the line 2x-3y+15=0
loris [4]

Answer:

y =- \frac{3}{2} x+1

Step-by-step explanation:

The equation of the given straight line is 2x - 3y + 15 = 0.

Now, we can express the equation as 3y = 2x + 15

⇒ y = \frac{2}{3} x+ 5 ..........(1)

The equation is in slope-intercept form and the slope is =\frac{2}{3}

Therefore, the equation of a straight line which is perpendicular to (1) is  

y = -\frac{3}{2} x+c {Where c is any constant}

{Since, the product of slopes of two perpendicular straight lines is -1}

Now, putting c = 1, we get the equation as y =- \frac{3}{2} x+1. (Answer)
