Answer:
This question needs rephrasing. It makes no sense.
Step-by-step explanation:
I dont understand the question?
to co.plete the square you have x2-10x+25+y2-14y+49=7+25+49 where 7+25+49 is the radius and -5,-7 is the center
3x-5y=4------eq1
4x+3y=15-------------eq2
multiply 3 to first eq and 5 to second eq.
9x-15y=12
20x+15y=75
subtract both eqs
29x=87 x=3 so put x in eq 1
3(3)-5y=4
5y=5
y=1
Answer:
.4
Step-by-step explanation:
you subtract the 3 from the left side and also the right leaving you with 10x=4. you then divide the 10 from both sides and you get x=4/10 which can simplify to 2/5 in decimal it is .4
The equatorial diameter of the earth is 7925 mi.
<u>Solution:
</u>
Given, The equatorial diameter of Jupiter is about 89,000 mi.
This is about 11.23 times the equatorial diameter of earth.
We have to find what is the equatorial diameter of earth? Round the nearest integer
Now, according to given information,
Equatorial Diameter of Jupiter = 11.23 equatorial diameter of earth
Hence, the equatorial diameter of the earth is 7925 mi.
