0.43 =
3/100 = 0.03
+
4/10 = 0.4
0.03 + 0.4 = 0.43.
Hope this helped☺☺
0 = x + 2 + x^2
x^2 + x + 2 = 0
a = 1, b = 1, c = 2
discriminant = b^2 - 4ac = 1^2 - (4 x 1 x 2) = 1 - 8 = -7
An excluded value is one where the bottom of the fraction = 0.
In your case 1-3x=0
1=3x
x=1/3
At this point, the function does not exist. If you were to draw a graph of it, there wouldn't be a y-value corresponding to x=1/3.

original=100%
75% off means
100%-75%=25%
remaining is 25%
it was sold for 45
therfor
25%=45
find 100%
just multipl it by 4 since 25 times 4=100
100%=45 times 4=180
originl price=180
answer is A
7. simle interest
I=PRT
P=principal=1000
I=interest=300
T=time=5
R=rate in percent form=?
300=1000*?*5
300=5000?
divide both sides by 5000
0.06=?
aka
6%
answer is 6%
b is answer
6. A
7. B
