Pythagorean theorem: a^2 + b^2 = c^2
The hypotenuse is always the c in the equation.
If the two side lengths they gave you are not the hypotenuse, then enter
4.5^2 + 5.6^2 in the calculator, then find the square root of that. :-)
Kelly .7 > Mary .49
Because kelly is actually .70 away from school when Mary is .49.
So Kelly would be farther away from school then Mary.
Answer:
$25
Step-by-step explanation:
-James and two cousins (that's 3 people)
3x=30+(15x3)
x being the amount of money they had each
<u>3x</u>=<u>75</u>
3 3 (we divide by three to find the amount of money each person had)
x=25 (each person had 25 dollars)
CHECK:
3<em>x25</em>=30+(15x3)
75=75
<u><em>true</em></u>
FINAL ANSWER:
James and his two cousins each received 25 dollars.

Seems to be aritmetic
an=a1+d(n-1) is aritmetic
a1=fist term
d=comon difference
n=which term
a4-a2=2d where d is the common difference
26-14=12
12=2d
6=d
so
a2-6=a1
14-6=8
an=8+6(n-1)
expand
an=8+6n-6
an=6n+2
3rd option
5 / 7 i think because 5 divided by 7 would be 5/7 as a fraction and she has 5/7 done
