For long division, you would put 700 in the middle, since the fraction would be 700/21. Then you would figure out how many times 21 goes into 700. Then you would subtract 700 by the amount it would be before it went above 700 by multiplying it by 21. Then, if it is not able to go into 700 fully, you would put a decimal and bring a 0 down.
Answer:
70 golf balls
Step-by-step explanation:
54+18+24-12-14=70
Answer:
Length is 38.7
Width is 19.3
4x length to 2x width
4+2=6
6x =116
x = 58/3
4 x 58/3 = 77.3
2 x 58/3 = 38.7
4:2
2:1
77.3/2 = 38.7
38.7/2 = 19.3
38.7 + 38.7 + 19.3 + 19.3 = 116
A)
The discriminant (radicand) is √(b^2-4ac), let us call this "d" for the discriminant.
If:
d<0, there are no real solutions (though there are two imaginary ones)
d=0, there is one real solution
d>0, there are two real solutions.
In this case, d=12^2-4(4)9
d=144-144
d=0
So there is one real solution.
B)
9x^2-30x+25=0
9x^2-15x-15x+25=0
3x(3x-5)-5(3x-5)=0
(3x-5)(3x-5)=0
(3x-5)^2=0
x=5/3
x=1 2/3
