He is 2km short of halfway:
⇒ 17 + 2 = 19 km
He is halfway:
19 x 2 = 38 km
Total distance for the hike = 38km
To figure out this question, look for the first number where both 25 and 9 are a factor of.
25*1 is 25 which isn't a factor of 9, so it won't be 25.
25*2 is 50, which isn't a factor of 9.
75 is not a factor of 9. (you know because you don't get a whole number when you divide 75 into 9.)
100 is not a factor of 9, nor is 125, 150, 175, or 200.
However, 225 is a factor of both 25 and 9. This makes sense because 25*9 is 225.
This means that the first package with both will be the 225th package.
Answer:
GCF is 2
Step-by-step explanation:
Factoring 34 leaves only 2 and 17.
90 is not divisible by 17 thus the GCF is 2.
D because the answer is 133
X^2 + 5x - 5 = 0
This is a quadratic equation that cannot be factored. It can be solved using the quadratic formula or by completing the square.
the quadratic formula is x = (-b +-sqrt(b^2 - 4ac))/2a
a is the coefficient of the x^2, b is the coefficient of the x, and c is the constant.
a = 1, b = 5, c = -5
x = (-5 +- sqrt(25+20))/2
x = (-5 +- sqrt(45))/2
x = (-5 + - 3 sqt 5))/2
x = (-5 + 3sqrt5)/2 and x = (-5 - 3sqrt5)/2
