Answer:
Hence the simplification of is
Step-by-step explanation:
<em>" Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler (usually shorter), </em>
<em>for example</em><em>: Simplification of a fraction to an irreducible fraction ". </em>
Here we are given a fraction as:
As both the numerator and denominator are divisible by a factor of 3 hence we take out the common factor and obtain the reduced fraction which is further irreducible.
As 66=3×22 and 81=3×27
Hence
Hence the simplification of is
Answer:
D
Step-by-step explanation:
So first you would set your two numbers as variables. Let y be the greater number and x be the smaller number. This means that our equation for y will be x + 4. Now all we need to do is add x and y. INSTEAD of using y, we will SUBSTITUDE with the equation for y, x + 4. Now our equation looks like
x + (x + 4) = 56
Answer:
angle 2 is 99
angle 7 is 81
Step-by-step explanation:
Angle 2 and the angle we are given are congruent because they are vertical.
Angle 7 and the angle we are given form a line, so they add up to 180.
180-99 = 81
