Let x and y be the two numbers.
x = y - 4
2y = 5x - 10
solve the system of equations:
2y = 5(y - 4) - 10
2y = 5y - 20 - 10
-3y = -30
y = 10
x = 10 - 4 = 6
Answer:
Step-by-step explanation:
well, in the equation y = kx
the constant or proportionality is k.
So, what do you think?
Did u mean to write
6b² -13b +6=0
6b² -9b-4b +6 = 0
3b(2b-3) - 2(2b-3)=0
(3b-2)(2b-3)=0
b= 2/3 or 3/2
hope this helps
Answer:
1000
Step-by-step explanation:
Primo car rental agency charges $44 per day plus $0.10 per mile.
44+0.10m= 44.1
ultimo car rental: 26+0.55m=26.55
26 + 0.55m = 4 * (44 + 0.10m )
26 + 0.55m = 176 + 0.40m
26 + 0.55m - 0.40m = 176 + 0.40m - 0.40m
26 + 0.15m = 176
0.15m = 150
150/0.15m
m= 1000
Answer:
-8
Step-by-step explanation:
-3x+7x-8=34+9x-2
we move the x's to the left and the numbers to the right
4x-9x=32+8
-5x=40
x=-40/5
x=-8
