They bought 5
Step-by-step explanation:
65x+40y=765
65(5)+40(11)=765
Answer:
12-x
Step-by-step explanation:
11 hours = 3
1 = 3 hours 40 minutes
-2x + (1/2)y = 18
(1/2)y = 2x + 18
y/2 = 2x + 18
y = 2*(2x + 18)
y = 2*2x + 2*18
y = 4x + 36
The x intercept is the value of x, when the y value is 0.
0 = 4x + 36
0 - 4x = 36
-4x = 36
x = 36/-4
x = -9
The x intercept is -9
I hope this helps.
