Answer: they need to cover 0.25 miles.
Step-by-step explanation:
Let x represent the total distance that they have to cover to get to Bernie's house.
Beth and Billy are biking to their friend Bernie's house and after 1 mile, Beth and Billy have traveled 4/5 of the total distance to Bernie's house. This would be expressed as
4.5 × x = 1
4x/5 = 1
Multiplying the left hand side and the right hand side of the equation by 5, it becomes
4x/5 × 5 = 1 × 5
4x = 5
Dividing the left hand side and the right hand side of the equation by 4, it becomes
4x/4 = 5/4
x = 1.25
Therefore, the remaining distance that they need to cover to arrive at Bernie's is
1.25 - 1 = 0.25 miles
Answer:
x=1, y=2
Step-by-step explanation:
solve by substitution so substitute x= 6y-11 in the next equation
3 (6y-11) - 2y = -1
18y -33-2y = -1
16y = 33-1
y= 32/16 =2
x= 6y -11 = 6*2 -11 = 12 -11 = 1
Answer:
Step-by-step explanation:
Factor out 6
I assume you mean 6x^2+30x+36, because that makes far more sense
6(x^2+5x+6) = 6(x^2 + 2x +3x +6)
(To find that it is 2x and 3x: 2 +3 = 5, 2 * 3 = 6)
Factor by grouping:
6* x(x+2) +3(x+2) = 6(x+3)(x+2)
For binomials, it could be either (6x+18) (x+2) or (x+3) (6x+12), depending on where you multiply the 6.
