-3(x + 4) + 15 = 6 - 4x......distribute the -3 thru the parenthesis
-3x - 12 + 15 = 6 - 4x....simplify
-3x + 3 = 6 - 4x...add 4x to both sides
-3x + 4x + 3 = 6....subtract 3 from both sides
-3x + 4x = 6 - 3....simplify
x = 3 <==

An angle measures 126° more than the measure of its supplementary angle. What is the measure of each angle?

Crazy boy [7]

Solution:

We know that:

A pair of supplementary angles always sum up to 180°

This means that:

$x + x + 126 = 180$

Step-by step calculations:

Combine like terms and simplify:

$x + x + 126 = 180$
=> $(x + x) + 126 = 180$
=> $2x + 126 = 180$

Subtract 126 both sides:

=> $2x + 126 - 126 = 180 - 126$
=> $2x = 54$

Divide 2 both sides:

=> $\frac{2x}{2} = \frac{54}{2}$
=> $x = 27$

This means that one angle is 27°. Let's find the other angle.

Finding the other angle:

$27 + 126 = Other \space\ angle$
=> $153 \space\ = Other \space\ angle$

Thus, the measure of the angles are 27° and 153°.

On,Saturday, Alexa babysat her neighbors kids for 180 minutes. Then, on Sunday she babysat her little brother for 2 hours.how ma

patriot [66]

Answer:

5 hours

Step-by-step explanation:

To change minutes to hours you will have to divide the total minutes by 60 (because 60 minutes is in one hour), in this situation it would look like this:

180/60 = 3

So, Alexa babysat for 3 hours on Saturday.

Now, just add the 3 hours from Saturday and 2 hours from Sunday and you get a total of 5 hours!

I hope this helps!!
