Step-by-step explanation:
-5×4=-20 put the x back
4×8=32
The length of his neck is longer than the length of his forearms by 44.86 %.
<h3>Calculations and Parameters:</h3>
Given:
Length of his neck = 14.72 inches
Length of his forearm = 25.81 cm
We know that:
1 inch = 2.54 cm
So, 14.72 inches = 14.72×2.54
=37.39 cm
So, the Length of his neck becomes 37.39 cm
So, the length of his neck is longer than the length of his forearms.
The difference between them is given by
37.39-25.81
=11.58 cm
so, the Percentage of change would be
11.58/25.81 * 100
=44.86%

Answer:
12 correct answers
Step-by-step explanation:
Since in the main part she scores 8.3 points for each question she answers correctly, we can assume that the number of questions she answers correctly=a
Therefor, the total number of points she achieved in the math test in the main part alone can be expressed as:
Total score(main part)=8.3×a=8.3a points
She also solved a bonus question worth=11 points
Consider expression 1 below
The total score in the whole test=Total score in the main part+Bonus points, where;
Total score in the whole test=110.6 points
Total score in the main part=8.3a points
Bonus points=11 points
Substituting the values in expression 1:
8.3a+11=110.6
8.3a=110.6-11
8.3a/8.3=99.6/8.3
a=12
Number of correct answers in the main part=a=12

the first step is to deal with the negative exponents, which causes numbers to go to the other side of the fraction
8x^{-9}+(-3x^{-3}y^{-2})(\frac{5}{x^6y^{-2}})
goes to

now we can simplify the multiplied terms

Now that we have common bases, we can add the 2 fractions together to get
