Answer:
x=14
Step-by-step explanation:
to find x you have to isolate it so you divide 3 by both sides and that leaves you with the answer
Answer:
16/25 = 0.64
Step-by-step explanation:
18 rolls are ones, so 32 rolls are not ones.
The experimental probability is 32/50 = 16/25 = 0.64.
Answer: 
Step-by-step explanation:
Equilateral triangle has equal sides, let the side be 
, then the perimeter is 
Therefore:
To find the altitude , we will apply Pythagoras theorem , that is
Therefore:
take the square root of both sides
75% of medicine this person took, you do that by doing 420/560 and you get .75. Then you move the decimal over twice since it asks for a percent and you get 75%
3x^2 + 6x - 10 = 0
x = [-6 +/- sqrt(^2 - 3*3*-10)] / 2*3
= 1.08 and -3.08
Other x -intercept is (-3.08,0)
