Answer to the observation is “ i noticed they’re all congruent “ and the rest are “ congruent “ for each line .
Answer: True, because if a number is a whole number, for instance, it must also be an integer and a rational.
Sqrt(x^2) = sqrt(20)
x = +2sqrt(5)
x = -2sqrt(5)
x1 = (- 0 + sqrt(0^2 - 4*1*(-20))) / (2*1)
X2 = (-0 - sqrt(0^2 - 4*1*(-20))) / (2*1)
Answer: D
Step-by-step explanation:Lets label hot dogs as 'h' and soft drinks as 's'
6h + 4s = 13 (Equation 1)
3h + 4s = 8.50 (Equation 2)
We can solve by process of elimination.
Subtract equation 1 from equation 2.
We get:
3h = 4.5
h = 1.5
So that means that the hot dog costs $1.50 which is answer choice D.
