Answer:
X will equal 10 x=10
Step-by-step explanation:
First subtract 100 from both sides to get x^2-20x=-100 then find c. (-b/2)^2 is the formula. then c=100 so add 100 to both sides. x^2-20x+100=200. Then Factor. (x-10)^2=0 is what you should get. then do square root. x-10=0. So now add 10 to both sides and you get x=10. Tada!
Answer:
7x+7 is obviously divisible by 7.
put in any value high enough and you can find the two three digit numbers.
Step-by-step explanation:
7p = 28....division property...divide both sides by 7
p = 28/7
p = 4 <== there are 4 players
Since x+y equals 5 that means x is 3 and y is 2 because 3+2=5. So now plug it in, 2(3)+3(2). Two multiplied by three is 6 and three times two is 6. So now it’s 6+6 which equals 12. So it’s 2(3)+3(2)=12
