Answer:
-2
Step-by-step explanation:
If you substitute x for 4, you have -4+2 to get -2.
Answer:
42m/s
Step-by-step explanation:
acceleration = speed/time
7.0 = s/6.0
42.0m/s = speed
We'll represent the distance as d and the time as t.
d= 3(t+7) because Gilda is 7 minutes late when travelling 3 mph
d= 4(t-5) because Gilda is 5 minutes early at 4 mph
d= 3t + 21
d= 4t -20
3t +21 =4t -20
41=t
d= 3(41) +21= 144
The distance is 144 miles.
Answer:
46°
Step-by-step explanation:
Given that :
Angle, A = 66°
Angle B = 68°
The sum of angles in a triangle is given by :
A + B + C = 180° (sum if angles una triangle)
66° + 68° + C = 180°
134° + C = 180°
C = 180° - 134°
C = 46°
Hence, angle C is 46°
150x^5-60x^4-119x^3+5x-6/5x-1
