Answer:
(-1, -6)
Step-by-step explanation:
2x-3y=16
2x-16=3y
13=5x-(2x-16)
13=5x-2x+16
-3=3x
-1=x
3y=2x-16
3y=-2-16
3y=-18
y=-6
Answer:
98.4 feets
Step-by-step explanation:
To obtain BC
we could make use of B as angle, the apply the trigonometric relation :
Tan B =adjacent / hypotenus
Tan B = DB / BC
Tan 26 = 48 / BC
0.4877325 = 48 / BC
BC = 48 / 0.4877325
BC = 98.4 feets
Answer:
its D 103°
Step-by-step explanation:
Sum of a pentagon=540
117+100+115+105+x=540
437+x=540
x=540-437
x=103°

Answer:
2.05 hours
Step-by-step explanation:
Using the given equation with the given time, we have ...
55x +35(2.5) = 200
55x = 112.5 . . . . . . . . subtract 87.5
x = 2.05 . . . . . . . . . . divide by 55
The car spends 2.05 hours at 55 mph.
