Answer:
the mean is 4.2
Step-by-step explanation:
B. 4.5=2m+g
f. 9.25=3m+2g
1.25=m
sub
b. 4.5=2(1.25)+g
f. 9.25=3(1.25)+2g
b. 4.5=2.5+g
f. 9.25=3.75+2g
minus 2.5 from both sides on the b. equaion and minus 3.75 from both sides on the f. equation
b. 2=g
f. 5.5=2g
divide both sides of f. equation by 2
b. 2=g
f. 2.75=g
2.75-2=0.75

A set of numbers is said to be Pythagorean triple if the sum of the squares of the lesser numbers equal the square of the remaining number,
A. 28² + 45² = 2809 ; 53² = 2809 ; EQUAL
B. 16² + 63² = 4225 ; 65²= 4225 ; EQUAL
C. 13² + 84² = 7225 ; 85² = 7225 ; EQUAL
D. 11² + 61² = 3842 ; 62² = 3844 ; NOT EQUAL
The answer is letter D.
Answer: -4/15
Step-by-step explanation: To add these two fractions together,
we start by finding their <em>Least Common Denominator</em> (LCD).
Since our denominators of 5 and 3 have no factors in common,
our least common denominator is 5 · 3 or 15.
In order to get a denominator of 15 in each fraction,
we multiply top and bottom of the first fraction by 3
and top and bottom of the second fraction by 5.
That gives us -9/15 + 5/15 which simplifies to -4/15.
As your last step, make sure that the fraction
that you end up with doesn't reduce.
In this case, -4/15 does not reduce but watch out for this last step.
