Step-by-step explanation:

Angle 1: (I solved this one last) 69 degrees :) . Because Angle 2 is 37 and we know the other existing angle is 74 we can do 74+37 and subtract that from 180.

Angle 2: 37 degrees. Because Angle 2 and the 53 degree angle add up to a right triangle (90 degrees) you can subtract 90-53 and get 37.

Angle 3: 106 degrees. Because the line is a straight line, all angles should add up to 180 degrees, and 180-74=106.

Angle 4: 21 degrees. Because we know that Angle 3 is 106 degrees, we can do (106+53) and then subtract from 180 because all angles in a triangle should equal 180 degrees.

The product of 1 1/2 and 2 is

Over [174]

Method 1:

Convert the mixed number to the improper fraction:

$1\dfrac{1}{2}=\dfrac{1\cdot2+1}{2}=\dfrac{3}{2}$

Make the product:

$1\dfrac{1}{2}\cdot2=\dfrac{3}{2}\cdot2$

<em>canceled 2</em>

$=\dfrac{3}{\not2_1}\cdot\not2^1}=\boxed{3}$

Method 2:

$1\dfrac{1}{2}=1+\dfrac{1}{2}$

$1\dfrac{1}{2}\cdot2=\left(1+\dfrac{1}{2}\right)\cdot2$

<em>use the distributive property a(b + c) = ab + ac</em>

$(1)(2)+\left(\dfrac{1}{2}\right)(2)=2+1=\boxed{3}$

Simplify the expression to one number using order of operations:

geniusboy [140]

<h2><u>COMBINED OPERATIONS</u></h2><h3>Exercise</h3>

First, let's solve the subtraction (in parentheses):

$\mathsf{\dfrac{-8\left(2-6\right)}{2}}$

$\mathsf{\dfrac{-8(-4)}{2}}$

Now, let's solve the multiplication. Remember: in multiplication, two negative numbers will give a positive number:

$\mathsf{\dfrac{-8(-4)}{2}}$

$\mathsf{\dfrac{32}{2}}$

Finally, let's solve the division:

$\mathsf{\dfrac{32}{2} = 16}$

<h3><u>Answer</u>: 16</h3>
