Answer:
u = 3.5 or (-7/2)
Step-by-step explanation:
8u - 7 = -40 + 5
8u - 7 = -35
8u = -28
u = 3.5
X=100°
y=180°-100°-50°
=30°

Answer:
Step-by-step explanation:
Let the number of hours driven by Maggie be x and that of Alan be y
If Maggie and Alan drive for a total of 32 hours, then;
x+y = 32 ..... 1
Also if Maggie drives three times the number of hours that Alan drives on their vacation, then x = 3y ...... 2
Substitute eqn 2 into 1;
x+y = 32
3y+y = 32
4y = 32
y = 32/4
y = 8 hours
Since x = 3x
x = 3(8)
x = 24 hours
Hence Maggie drives for 24 hours and Alan drives for 8 hours
