<h2>Lesson: Adding or Sutracting Fractions</h2>
<em>Convert mixed number to improper fraction.</em>
<em>3 5/6=23/6</em>
<em>23/6+3/2</em>
<em>23/6+9/6</em>
<em>Denominators are equal, and it should be combine the. fractions.</em>
<em>23+9/6</em>
<em>Add the numbers from left to right.</em>
<em>23+9=32</em>
<em>32/6</em>
<em>Make sure to cancel by the common factor of 2.</em>

Answer:
x=6
Step-by-step explanation:
5x^2-136=44
add 136 to both sides

x^2= 36
take square root of both sides
x=6
Answer:
GCF(15a; 28b²) = 1
Equation 1. N+D=500
equation 2 5N+10D=3000
This is for equation 1
N=500-d
Substitute into equations 2 and solve for D
5N+10D=3000
5(500-D)+10D=3000
2500-5D+10D=3000
5D=500
D=100
Lets go back the equation 1
N=500-D
N=500-100
N=400
there are 400 Nickles and 100 Dimes
