Please solve for c :3 3c - 2 = 5(c+2)

Viefleur [7K]

Hello.

First of all, solve 5(c+2) by applying the distributive property.

I mean, 5*c and 5*2

So rewrite:

3c - 2 = 5c + 10

Now, you have to solve for c and then move all the Cs to the left of equal and change them sign, same to all known terms but move them to the right instead!

3c - 5c = 10 + 2

-2c = 12

The c can't be negative so divide both terms for -1

2c = -12

divide both terms for 2

2c/2 = -12/2

c = -6

Write an equation (in slope-intercept form) that is parallel to 4x + 5y = 10 and has the same y-intercept as -3x - 4y = 24.

mart [117]

Answer:

y = -4/5 x - 6

Step-by-step explanation:

First turn both standard form equations to slope-intercept form.

4x + 5y = 10 -3x - 4y = 24

-4x -4x +3x +3x

5y = -4x + 10 -4y = 3x + 24

5 5 -4 -4

y = -4/5 x + 2. y = -3/4 x - 6

Now that you have each in slope-intercept form, we can begin the magic.

So we know that this line's y-intercept will be -6.

Not to mention since it's parallel, that means it will share the same slope as y = -4/5 x + 2, which the slope is -4/5. All together it will be

y = -4/5 x - 6. Now we can graph the line's to see if we we're right. (Look at graphs, attached above⤴⤴⤴) As you can see they are parallel.

Hope this helped :)

in 2015, there were approximately 33,600 firearm fatalities (homicides and suicides). Express this quantity in deaths per hour.

fomenos

The answer would be3.8356164375.This is because you have to divide 33,600 by 365 which gives you 92.0547945.The number 365 because of the amount days in a year.So that gave you the deaths per day.So then you divide it by 24.The number 24 because of 24 hours in a day.So, 92.0547945 by 24, this will give you the hourly rate of deaths.
